Shrinkwrap and derive? What's the difference? | Autodesk Inventor

welcome to deify cut tips wreaths I'm gonna start this tutorial off with a bit of a story but a background a little anecdote as to I am doing this tutorial might explain to a few people where you would use this why you would want to do this in the first place in case that's not clear so I was in the office earlier on this week and a guy came over to my desk called me over to his desk nice guy Hungarian chopped calm pronounce his name not going to trial and Barriss myself but he was like me I've got this assembly here it's been sent to me by it by a client or a supply em I wasn't this assembly here it was very similar one was a machine but it was similar in size in nature and he was like you've sent it as a step of opened it up and it's exploded that step filing the hundreds of parts and pieces and that's fair enough but I want to stick it in the fault it's not going in a fault and I was like dude I'm just gonna stop you there bro you're not putting that in my fault you are not putting those 100 and something pieces of crap in my vault he was like hmm okay so mmm what do I do I was like well why are you using this why do you have this what are you going to do with it and he was like well this is the customer's assembly they've give it to me and they want to see their machine on our factory layout so I need to put it in my assembly and just show it there that was all right fine that's not a problem I'll allow you to do that but you're not putting on written some of the pieces in my fault cuz why do you need a hundred-and-something pieces why don't you simplify the assembly down into one part and then just have one part instead of a hundred parts hmm yeah that would be better wouldn't it it would be how do I do that okay okay is that's where we are that's where we're at so we want to take an assembly that has hundreds of parts we want to simplify it down into one object because we don't need a bill of materials for it we don't need to have hundreds of parts if they can be represented as one piece instead and that's one of the reasons that you would use simplification where a thing where things get a little bit confusing is the the different methods that inventor has for simplifying assemblies this is there's at least three and that's where people get a bit confused because they've heard the word shrink-wrap being used Mooncraft that sounds sounds meaningful and purposeful I want to shrink wrap something it sounds like I know what I'm doing I want to shrink wrap it show me how to shrink wrap but but even someone's mentioned derive derive compote drive part do I derive or shrink wrap what's the difference between derive and shrink wrap oh my new inventor has this tab along the top simplify in sky can create simplified part I've heard shrink wrap simplify something why would I shrink wrap and then why would I do this one here so the purpose of this video is to explain what the different simplification methods are where you would use each one and the differences between them the two long didn't read the TLDR of it all is they all kind of do the same thing emphasis on the word kind it the end result is the same you're taking an assembly and after you've done either three options you're ending up with a single part and IPT which looks like the assembly but it's a part so you end up with the same result but there's three different ways of getting there that's that's that in a nutshell that's it so what we're going to do is we're going to look at the three different options and explain what they are so well what we'll start with shrink-wrap right we'll start with the shrink-wrap so with shrink wrap the whole point why not the whole point but one the main purpose of shrink wrap originally when it was first introduced didn't when men around about 2012 who cares doesn't matter it's not important one of the original purpose of shrink wrap was sending out your assemblies to somebody else not receiving them and using them but sending them out I want to send some say this's our assembly right we designed this sir this unit here and we want to send this to a to a client or a supplier and we want them to do they just need to use it in their assemblies but we don't want to give them our IP right we don't want to give them our intellectual property we don't want them to be able to reverse engineer it so we shrink wrap it down into a part and we remove detail whilst we're doing it that's the point of shrink wrap so you're still gonna end up with a single IP T but you're gonna remove some detail from it as you doing it how do you shrink wrap well there's a number of different ways of doing it one of the the most common way and the easiest way of doing that is to when you when you've got the assembly open you go to the component drop-down and you select the shrink wrap option there is a drop down here which has shrink wrap substitute in it but we're not going to use that one right we're just stick with a straightforward shrink wrap because we're going to be making a new part we're going to funnel this assembly into an IP T it's going to create a physical IP teapot so we need to give that a name so call this something that you recognize and that the recipient will recognize so my product simplified sometimes I'll do the template you can leave that as a standard IP T and then for the location just drop it somewhere where you're going to be finding it later on so my easy to find so you desktop something like that click Save and then for the BOM structure it's not that important but if if you know that the recipient uses inventor and they're going to be sticking this in their assemblies you might want to set it as reference so it doesn't it's not included in their builders materials and you know it's just that extra thing it's just an extra step you know what you're doing you've said is reference you've been courteous I know you don't want this it to be in your BOM so I'm gonna set as reference I'm going to take that work away from you because I'm a I'm a chump and they'll be they'll be appreciative of that if they know what they're doing then click OK that then opens up the shrink wrap dialog box right you got if you got a different set of options in the shrink wrap dialog box then as if you were to go to the other options right but essentially you were going we're heading towards the same goal making an IP T so the first set of options along the top you get this style the style matters by default and the most common option is the option on the right-hand side which is a single composite feature the IP t will be a surface model of the original assembly that just means it's more like way to surfaces of thin walled structures a thin walled object it doesn't have any mass doesn't have any internal mass it makes it lightweight what you doing here you turn in an assembly into a part you're converting your crumb and hundreds of parts in a one so you want to make it as lightweight as possible and a surface model is the best we have gone about doing that if you want to go for the other options you can say make it a solid body and then make sure you keep the seams between the faces if you want to see you know gaps and edges and stuff between parts it look the same it will look the same even if you call for a surface it'll still keep the textures in the colors and the appearances so it doesn't really matter but the best option is to keep it with a surface right the simplification options right this is where things start to fall apart a little bit because it's not the best it's not the best if you want to make sure that you're retaining as much IP as possible and you're not given them more information than they need to see you can start to simplify it by removing geometry by visibility which is not the best explanation of what this does removing geometry vibe by visibility removes objects based on what you can see from the outside that's the saw the the most simplest way I can explain this however what happens is something completely different it just seems to be random so in the only option you've got as well as this slide bar you just slide it up and you be basing it on a percentage value which means nothing than nobody so remove 35% of parts and faces by visibility is essentially what's going on here then you click preview and it'll do its thing right and before I do that I'm gonna undo whole puchen because we only want to see the results of this I will get rid of that and that and then click preview so it's removing 35% of parts by visibility or parts and faces by visibility and then that happens and you're like ah that's not the desired effect I wanted to keep this how do I select this to keep this well you can't unfortunately you can't you just have to remove you have to just drag the slide bar down and hit preview until it starts adding bits again and you're like can I get away with this possibly I could possibly get away with Apple now I've got a bar here floating in space that's not brilliant that's not great this is no good to me at all so let's select whole parts only and click preview see if that makes difference well it does a little bit but there's still things sort of floating off here can I get away with that possibly you can see what I mean we're now randomly got a component missing here so it's not the Penn dog that the monitor is now floating one of the hinges is just the one of the arm lengths has gone off it's not brilliant at all so you can maybe uncheck that don't do that let's bring everything back on so everything's back let's remove part by size and then the size ratio is again just a percentage so what it does is essentially it puts a big box around the entire assembly and based on the size of that and higher bounding box or remove parts that are say 30% and below the size of that overall bounding box let's hit preview and you end up with this yeah no no that's no good to me at all that is no good seeing drop this down at maybe 10% and preview and this still is still not the best you see what I mean so shrink wrap isn't the best if you can if you're not bothered about IP you can just keep everything on and hopefully the part file that you end up with isn't going to be too big right hole puching fact this is something you could maybe use right hole patching will put a surface and blank up any gaps and holes that are in your model and that doesn't just mean circles it's not just drilled holes it means anything so like for example this box here this there's a lip that runs along the top of the box that's classed as a hole so if we say patch up all the holes it'll patch up the top of the box it'll patch up these circles here and you've blunt any faces that it sees it's it works quite well actually it works quite well so that might be the best option that you've got for retaining intellectual property so we'll keep with that we'll patch up all the holes right include other objects right you might want to include work geometry some sketches that they've got in there in most cases you don't you just want to uncheck all of these options here you want to go for reduce memory mode that means that if we if we remember the original assembly it had a browser tree you can see all the parts do you want people to see the browser nodes from the original assembly well if you don't select reduce memory mode it just there's just less detail in the part file remove all internal voids so what it'll try and do is so we've patched at the holes if you want to sort of fill that area as well you can ask it do that the results going to be completely different based on what assembly you've gone whether you've got any voids how big they are if there's anything in those voids so you can try the narrow that you can do at once with the ticked you can do it again with a ton ticked and see what the difference is and then make a decision based on that break link right this one's quite important it but that's not it is important but you can change your mind later if you select break link there'll be no link between you assembly and the part you've made if you don't break the link what can happen is if your original assembly changes so you might add some new parts and you might move some of the legs around make them increased height well you shrinkwrap update you might want that happen you might not if you've sent it to the client well it doesn't matter because it's not going to be able to update is it because it's over on a client site so in most cases you probably do want to break the link click OK and then what it's going to do is now funnel all of those assembly parts and blends them down shrink Rupp's them into a single part file and then the result well it's anyone's guess I haven't done this yet I haven't practiced this a tours you can probably tell because I'm just I'm just trying to fill type I'm just I'm just govern I'm ad-libbing is the purling that's the proper word isn't an odd living filling in tighten with waffle before the there we go there we go we now have it done so this is the IPT finished and i would say as far as IP goes we've filled in some holes we've blanked some plates and we've now ended up with a single pot that can't be reverse engineered because it doesn't have a browser tree because we've selected reduced memory mode and broke the link there's no tree structure here so the the recipient can't see what contributes towards this assembly so you would then do is save this that saves it to my desktop and we've now got a shrink-wrapped simplified single pot representation of the assembly the assembly itself is going to be quite large though so there it is it's 24 Meg IPT which it's not let's not like bar actually on most systems that should cope with it that should be fine and that is shrink wrap that's it does that make sense nope so oh so because it's it's relatively simple so that's what shrink wrap does you can then send that off to a client and then they have your assembly and they can use it if they want right that's the first option right the second option is derive write derive gives you a few more options right let's shut this down and let's shut that down and then let's let's start a new IP T right so derive component or derive part drive assembly works the complete opposite way around to ringwraith you start with an empty part file and then you're pulling the assembly into the part so you work on the other way around so to do this you go to the manage tab and then you select derive you browse to your assembly we'll stick with the same one for consistency and then we'll click open read the derive command gives you more flexibility for excluding components than shrink-wrap but you need to be a little bit careful because if your original assembly has any view reps any assembly view representations set that can restrict what you can do so the best option is to go to the representation tab and if it's set to default the default view rep is locked right if you're telling vendor I want to derive the default lock design view into a part file it's not gonna let you exclude any of the parts so what you need to do is either make a new view rep that's unlocked or use an existing one so you can see we've got one here called screen well I don't know what's in the representation screen so what can cancel this right well cancel this will do this properly and then we'll reopen the assembly we'll reopen the test station will go to representations view notice how the does the default view rep is locked it's got a little padlock next to it it's not much used to me so it can create a new view rep and then we will call this and what coolest Drive yeah we'll just call it four derived right well just call it four derive so we're know exactly what it is and that includes all the components everything's visible so we'll save this and then we'll shut it down we'll go back to our part and we'll read derive so we'll go back to derive pick the test station and then on the representation tab we'll make sure four derive is selected now if there's a ticket box here which means that the the derived part is associatively linked to the the view rep do we want that well it depends on your use case doesn't it if you're making if you're deriving this this part so that it always looks the same as the original assembly then you want that ticked but then that's gonna stop you from excluding the part because if you're excluding the part and it's not gonna look the same as it so you might want to uncheck this so it isn't associative he linked to the original assembly then you can come into the the component selection bit and you can say right well I'm giving this to a client I'm giving this to a client so I don't want them to see these two electrical boxes here so that's these two pieces here I can then click the yellow circle and that turns into a grey little slash which if you look up here hover over the grey slash it excludes the selected component so I want to exclude that I want to exclude that these boxes here that's these things here well I don't want them to have that that not all the reading is the they just need the frame they need the frame when the bits on top I'm saying the bits on top is a comic bother to exclude everything but they just need those and then we can make sure this comes in as a surface it's like just like they shrink wrap we're gonna say well we want to make this into a surface and then that's pretty much it the rest of them if you want to like for example the monitor screen the monitor screen if you didn't want them to see the actual monitor screen you can ask an vendor to convert it into a bounding box so you'd click the little yellow circle until it turns into a bounding box now I don't know which one of these parts that are right so we can we would have to then drill down into the tree structure to find that and then convert that into a box and it will convert the monitor screen in it just a green box yeah yeah you might not want to do that you might want to do that it's the entirely use case dependent isn't it really all right then so that's excluding parts and that's converting parts in the bounding boxes right there's a couple of other options there but that's the main things you'd want to do if you go to other well this is the way you can start including parameters and different bits of pieces work planes and sketches and stuff but and by default it just excludes everything I don't need any of that rubbish everything's excluded the representations well we start from the the derived design view but when over that were fine with that if you had certain or certain positional representations you know you might have you might be driving a crane which has got an up in a down position you might want to derive the down position for example so you could pick that here options well this is where that gives you some of the shrink-wrap options but if you were gonna use those you just use shrink wrap wouldn't you soon mmm no will not go here will not use any of these but you can also patch holes if you want to by default all the options are deselected if you want to patch the holes you can say well yeah that's patched the holes whilst we're doing it that gives us that little extra level of safety so we'll patch those holes scale they're right you don't get this option with fair with shrink wrap that's what I'm saying we're doing the same thing you get the same end result but you got a few more options a few different options based on which method you go with so derive assembly lets you scale the model up or down now this is quite handy when people get given assemblies which are in a different unit set so you might be given something that was modeled in inches but you want to end millimeters so you can maybe scale it up by 25.4 and it'll change the scale factor or you can maybe just say well it's a little bit too big I want to scale it down by 0.1 and you'll get a smaller IPT or if you just know if you have no no interest whatsoever in changing the scale factor you can just leave it as one mirrored assembly this is another good option you might be wanting to create a left in a right hand part so you might be say an aeroplane wing you've modeled the entire right wing you want the exact same thing for the left hand side well you can derive that right assembly into the the left hand side select mirror and I want to mirror it across a certain museu your planes is sent lines Bush so you can do that you can mirror it as you deriving it use the color override from the source component well yes if is if you just as long as you don't have any need to change the colors and the textures on the drive part just leave this ticked and it will use the original colors and textures from the original assembly in the part you're making reduce memory mode of being over that we want that ticked and then remove all internal voids well we've seen that as well and then you click OK and then what it does is it funnels that assembly into this part very similar in the way shrink-wrap work but we're going the other way round and we've given it a few extra commands we've given it a few extra instructions take away those boxes at the bottom get rid of these electrical components here and then blank up this this monitor face here and we end up with that looking tasty and crispy creamy and then you would say save that to the desktop and then this is going to be the derived version of my product save that yes I know it's not Newsom is not in the project and then that's it done right in terms of file size this one is - that one there I don't know what the sizes let's have a look it's gonna pop off it's only nine megabytes that's a lot smaller blasts cuz it's got less detail in it doesn't have these boxes in so yeah that's a but a better version of it exactly the same thing it's still an IP T it's still simplified down from the same assembly but we just got to the end result in a different way now there's another use case for derive part right that this isn't the only way or the only reason why you use derive part another way is sort of like skeletal modeling almost but not really you might have an assembly which is going to be the start point of a new design it's going to be you might have like a base plate which you've modeled up and you want that base plate to be the start of all your future parts well what you can do is you can say right I want to start a new IP T and then the start point I want this I want this block to be a start point and I've already modeled it so what you would do is you've got to manage you got a derive and you'd say right well you say let's pick something random that we can use that looks a bit too ugly that's this thing here right this is going to be the start point of a new design so you can derive that part into this pot and it just drops it in and you can just say okay fine everything's fine everything's tickety-boo and that is now the start point of a new design you can now start sketching stuff on in say on a sketch here I want to create a new geometry off here and that's now the start point of every new model and if you decide well okay well there's going to be a revision at this original start point you can code the original model change that it'll cut a hole through it increase the length of this of this thread and then anything that you've created and derived this in it will update that's another use of derive pot very useful actually is really really useful if you've got a need to do that so that's another reason you'd use to write pot right the final the final god this is a long video I know if you've stuck with me this long well done because because because I don't script these videos at all right I literally just start them up and I just walk I have no I have no idea for making any sense or whether this is actually good information I have no idea right but the third option the third option is the most recent one it's the simplified one this does exactly the same thing a shrink wrap and drive part right it does exactly the same thing but it's more user friendly right it's more newbie friendly what it allows you to do is just say I want to make a simplified part right you just click it it gives you the same box a shrink wrap and drive pop we're making a new IPT right and this is going to be the simplified part using the ribbon tab and we'll save this to the desktop as well alongside the other two yes and then you just click OK and that is it it just derives the entire assembly into a part file no options no messing about no tacky boxes no circles no nothing it just does it and it's newbie friendly it doesn't give you any options and I'm still filling time I'm thinking when's this green bar gonna reach the end and just do it but that's what it does that's what it does it just skips all the crap it skips all the junk you're not interested in all these to keep oxygen I just want to confirm my assembly in your part file don't hassle me with any nonsense just go and do it and it'll do it the problem with this option is that it's going to result in the largest assembly because it doesn't give you the option to convert it into a surface it's only giving you the option of picking solid models so it's gonna be larger than the other two and it's gonna have more detail in it than the other two which is in some cases that might be fine you might not care but there it is click Save and that's it done so you get the same browser tree you get the same node so this little note here is a link back to the original assembly exactly the same node as you get with derived part and shrink wrap so if we expand that because we didn't get the option of reduced memory mode we got all the nodes in here if you right-click on the node you get the same options as you do in the other two you can edit the drive to cemani so if you think oh well actually I do want to change some stuff well you now get the option because you can edit it and start excluding stuff and you can break the link as well if you right-click on that node I didn't show you this near the two examples cuz I was in tension and leaving it until the end but if you do retain a link between the original assembly and the part that you've created you can break that link afterwards I would always recommend that you suppress the link because I've lost count of the amount of times people have broken the link and then the one I need that link back I need to update it well you can't you've broken it it can't be done if you suppress it it just may be that it severs the link temporarily and you can re-enable it later on it's always the best option unless you are setting it out or client right so that's the simplified option now if we go to the desktop and look at the the file size of this one which is using the ribbon tab this one is 36 megabytes in size so it's it's much bigger than the other two 36 24 and nine megabytes in size so this option gives you the simplest way of doing it but it's the largest file size and with the with the less options during transit right the other option that you've got as well is you can you can you can play around with this a little bit right you've got two other options here include components right what this will do this will allow you to manually select the objects in the assembly that you want to simplify right but you have to do that before you do this but so you say right I want it include components I want to create a simplified assembly of this this this this may be these bits here at the top of the bench that there and that there want the uprights and then I want the cross members right just give me an assembly with those in please that's all I want so you pick those right click and okay what it does is it creates a view rep with just those bits in that you clicked and then you just click simplify part for this less parts drop it on the desktop again save it there yes I know you've mentioned and then click OK and then you got a much much smaller assembly with just those bits in that you ticked and that's it you've got the desktop again and when I'm safely and over you know we need to save it first okay and then open and then there it is and then this one will be even smaller again this one should only be a couple of Meg marks yep two Meg 1.92 so that's what simplify does it's exactly the same thing as shrink wrap and derive but it just gets there in a different way it's more user-friendly in the bits that I want to simplify then simplify it now the third option here which is defined envelopes but we've seen that an action and derive part this allows you to pick some bits and it will convert them into a bounding box so it just converts them into a solid so maybe you do want to simplify these models as he pushing them into two other programs you might be sending these assemblies over to something I rev it and rev it doesn't need to say all the grooves and all the the profiles of all the frames you just Rev it just needs to know that there's something there well you can simplify them down into enveloped pieces and then simplify it and then click test station simplified come on the screen is quite far away right there we go and then we can put that on the desktop so this is the same as the other one but the the uprights are simplified down into boxes and okay and then that creates us the assembly with the parts uprights as the bounding boxes there we go and you can then got your desktop and then you can say right where I can saved it again I might save it okay and then you can go to your desktop pick up that one there which I don't know if it's gonna be smaller again I'm gonna Majan and run about the same size oh no it's smaller again 1.65 megabytes and you can take that and then send it in an email or you'll send it to an email or do whatever you want to it put on a network drive give it to somebody else and that's your assembly simplified again all right if you've made it to the end of this I genuinely commend you I bow before you with respect and admiration because honestly my lips are numb from talking so much but I think I've covered all the the simplification options where you would use them why you'd use them and what the different benefits are to the different simplification methods hopefully it made sense if it didn't let me let me know in the comments and I could either redo this with a bit more structure this is this is just typical TFI it's like well I know what I want to do I'll just open up and I'll open up and then I'll just do it but obvious ence if it did press like on the video if you haven't subscribed already do subscribe obviously more these type of things coming in the future as I think I'm up and his issues happen in the office and gives me ideas for videos and stuff and yeah thanks very much and I'll see it later on
