Creo Parametric - Coordinate Systems

and creo parametric coordinate systems have a number of uses including creating other datum features importing points assembling components and for routed systems they're used as entry ports for cabling and start points for piping here I have an elbow corner model that I've imported it is from Clippard I got it from trace parts and if I want to create another default coordinate system you go to the datum overflow menu here we have default coordinate system and there we've created another coordinate system and the name is a CS 0 the a is because I created it at the Assembly level CS for coordinate system and 0 because numbering starts with 0 if I want to create other additional coordinate systems for example for my start points for piping I might just need to start off by creating some axes first let's create an axis through the center of this cylinder that's good and I'm going to deselect that one and then let's select this cylindrical surface and I'll create an axis from the mini toolbar now that I have both of those axes in there I can click on the command for creating a coordinate system and let's select this axis I will hold down the control key to select this flat surface and there you can see the coordinate system preview that I'm getting let's click over to the orientation tab right now it is using this surface to determine the X direction since I'm using this for piping I need Z to point in that direction so I will go to the drop-down list and change this to Z if Z was pointing in the wrong direction I could use the flip button in order to change it but that's good but that is not enough to orient my coordinate system that's why the ok button is currently grayed out and so for orienting this one I could use a datum plane if I had one but I'll just use this flat surface now I'll use that for determining the Y direction that is good let's go to the properties tab since this is going to be used for piping I'm gonna change the name to end zero hit the enter key so it takes the value in there here we have the option to display the coordinate system name I'm leaving that checked and here's another option that was added I think around creo parametric 4.0 or so to display zoom dependent in other words that way the size of it is going to be determined by how big you are zoomed in or not you'll notice that it's sort of like staying the same size regardless of how I'm assuming in or not usually I don't check that lets click the ok button and there I have my first coordinate system created and I can repeat the process for the other one and I can start off by selecting the axis here we have the command in the mini toolbar let's hold down the control key select this surface and then for the orientation right now again it's using that surface for X let's change this to Z and let's click in the other collector by the way you'll also have the ability to hold down the right mouse button to change which is the active collector so here's the second Direction collector I'll just use this other flat surface over here and that one is determining Y that is fine and for the name let's change this to end one and so in that way I've created a couple of start points for routing my piping let's take a look at some other different methods of creating coordinate systems and for this one I'm going to jump over to creo simulate for a moment so here I am in a simulation model if you go to the refine model tab you also have the ability to create datum features in creo simulate I'll click on the coordinate system command and let's select this surface over here I will hold down the control key and select that axis and there you can see the preview of the coordinate system and here is one of the difference between coordinate systems in creo parametric versus creo simulate I have a drop-down list to use a cylindrical or spherical coordinate system as opposed to just a Cartesian coordinate system and in this particular case I can choose I want to create a cylindrical coordinate system and right now to use mat surface to determine theta equals zero I actually want that to determine the z direction and then for using the other orientation let me use clicking this collector over here and I'll just grab one of the datum planes let's up them like that one let's choose top right now it's using the datum plane called top to determine theta equals 90 degrees I could use the drop down unless to change this to theta equals zero and you can see how the coordinate system is oriented and you have flip buttons if you want the Z Direction to be in the opposite direction and again from the properties tab you can change the name if you want to and since I'm creating this in a part the default name is CS followed by a number there's no a in there because I'm not in an assembly let's click the ok button and that there I have a new coordinate system created and again I could create a spherical coordinate system as well and the reason that you have this in creo simulate is sometimes when you're defining different constraints or loads you want to define them in a cylindrical or spherical system instead now there's one interesting thing about creating coordinate systems versus other kinds of datum features in creo simulate let's say I create a plane just gonna pick this surface I'll leave the other selections in there and click the ok button so here I have a datum plane DTM 3 and it's in this folder for simulation features when you're creating datum features in creo simulate they only exist inside of creo simulate they don't exist if I switch back over to part mode if you want datum features available in part mode you can promote them so for example I will select this datum plane and then again on the refine model tab if you go to the datum overflow here is the promotes command and now you'll notice that the datum plane no longer appears in the simulation features folder which you can collapse and expand but now appears in the regular part of the model tree but for coordinate systems if I select this one which again is a cylindrical coordinate system you'll notice that promote is greyed out so you can promote datum points datum axes datum planes but you can't promote datum coordinate systems because in part mode you only have those Cartesian coordinate systems now I am back over in creo parametric I created a text file containing a bunch of different points that I want to import here you can see that I've got one two three seven different points in here and you can see that the first column of values are all the same here in the second column is 0 60 120 180 240 300 and 360 and the final column are all zeros so again this is just a text file it is space delimited and I can use this for creating datum points in creo parametric let's create a brand new part and I'll leave the default name in here let's click the ok button and I've got my default coordinate system let's go to the point drop-down menu and here we have the ability to create points offset from a coordinate system so even though when I create coordinate systems they're all going to be Cartesian when I create points offset from a coordinate system I can choose how I'm using that coordinate system so let's click on the command and here in the datum point dialog box the first thing that I want to know is what reference I want to use in order to locate those points and that reference is going to be a coordinate system I'll select the default coordinate system you can pick it out of the model tree or the graphics area and here we have the drop-down list for a Cartesian cylindrical or spherical for bringing in those points I'm going to click on the import button and here I have the points file and it's just a text file with a dot TTS extension let's click the import button so there I have those different points and so the X values and the Z values are the same the Y values though are increasing you can see that relative to this coordinate system let's click the ok button and there I have my points and with the points still selected if I go to the datum overflow menu and go to curve I can create a curve through those points and it's going to be a straight line so there you can see that point file imported offset from the coordinate system let's repeat that process again if I go to the drop down menu offset coordinate system pick the same default coordinate system but this time instead of importing them in Cartesian coordinates I'm going to import them in cylindrical coordinates let's click the import button and select my points file and click import and you'll notice now R is going to be the first column the second column is theta and that last value of 360 automatically got changed to 0 and here we have the Z value which is all 0 when I click the ok button let's zoom in over here essentially I have the points going in a circle with a radius of 10 and once again if I go to the datum overflow menu and then curve and then curve through points well now I'm essentially going to end up getting a circle through here and lastly I can create point offset from a coordinate system and do spiracle instead let's select our reference coordinate system and then import those points once more put the import button and this case here the points are going to end up on top of each other because of the our Phi and sy I believe it is or is that a theta that they use here click the ok button and the points are in there and for something a little more interesting if I go to the points offset from a coordinate system unless you spherical pick the reference coordinate system instead and then click import I'm gonna do a slightly different file over here and click okay and that way we have the points not co-located and once again datum curve curve through points you can see that funky curve over there that's created and hit the check mark and turn off some of these different datums in here so you can see that how you're using a coordinate system has a vastly different effect on the geometry that's going to end up being generated now let's take a look at a couple other uses and ways of creating coordinate systems and here I have a molex connector downloaded right from molex com and one thing I really appreciate about molex is that they give you these fully featured models here they have creo parametric models and I've got all the different features inside of here that is really really nice of them to provide so let's take a look at how I would use this so this is a connector that's going to be used for cabling and so one thing that I'm going to want inside of here is some entry ports to use and for these different entry ports I think to do the wires are going to be routed on through this surface so I'd like to create a single entry coordinate system case I just want to route all the wires into one coordinate system and you can also create individual coordinate systems if you want to do pin to pin routing so the way that I will do that let me turn on some other display of one other datum plane in here I will create a coordinate system and I'll select the surface and hold down the control key and essentially gonna pick enough references until you are able to locate a point in this case here the intersection of three planes gave me a point and now for the orientation we know that we want the Z Direction going out so this surface I want it to determine Z and Z is pointing out that's good and right now to use them a datum plane called side to determine Y now let's I like to use geometry let's use this flat surface to determine okay actually that's how I want to use it using Y for that one that's good and then for properties let's change the name here to entry if I can spell and that's good for my single entry coordinate system and right now I am not seeing it because I need to turn on my coordinate system display so there we have the entry coordinate system let's now take a look at another method of creating coordinate systems and that's with using a sketch so for my individual pin to pin routing that I want to do I'm going to create a sketch I'll just pick this surface over here and for the orientation let's use this surface to face actually let me use this surface to face the top of the screen because I want to select oops something that I'm going to use as a sketch reference later on so let's click the sketch button and now here I am in sketch mode and I'm just gonna create a couple normally I would create all eight of them inside of here but that'll be a little tedious for this demonstration and so let me hold down the right mouse button and get to references and I'm gonna pick a couple additional surfaces inside of there that'll help me locate my coordinate systems and there again I'm just going to do two in here just for the sake of this demonstration as opposed to doing all eight let me go to my sketch view and I'm gonna create some construction geometry let's go to construction mode and I'm just gonna sketch in a line that goes from this intersection over here down to that intersection and also from just make sure I'm snapping to the right place down - over there and right now it's hard to see them so let me change from a shaded mode into a no hidden line mode and so there you can see the construction geometry that I've created and for the geometry that's gonna be inside of here I'm gonna go to the datum group and create a coordinate system so you can create coordinate systems inside of sketch mode and the reason I create that construction geometry it's just so I could snap right to the middle there and you'll notice when you are creating them inside of here let me go back to a shaded mode shaded with edges and deselect them the z-axis is pointing out in the direction of the routing and for cabling X&Y it doesn't really matter I have a couple of weak dimensions inside of here if you want to make them strong you can just swipe a box over all the different dimensions and then from the mini toolbar up I'm seeing the strong which one of these is strong oh there it is that one is for creating strong but it's also the keyboard shortcut of ctrl T so that way I have strong dimensions but a lot of times I don't bother doing that for creating coordinate systems for routing so that's good I will hit the check mark and now I have the coordinate systems in the sketch there you don't have them individually listed in the model tree sometimes if I really want to change the names of the entry ports I will create a coordinate system on top of one of the coordinate systems and here you'll notice that when I'm referencing an existing coordinate system you can choose the offset from that original coordinate system and here you have Cartesian cylindrical spherical or from file I've never used that one but we'll leave it cartesian it does matter because i'm going to create it right on top of where it is now when i go to orientation since i reference a coordinate system you're able to change the orientation so you can rotate about X Y or Z in order to get the direction that way that you want but this is fine for what I want except I'm going to name this entry 1 and then click the ok' button and so now I've got a coordinate system on top of the original coordinate system and I can take that entry coordinate system and pattern it and for the type of pattern instead of using a dimension pattern I'll use a point pattern and here's one of the secrets about a point pattern a point pattern can accept a sketch of points or a sketch of coordinate systems and so that way if I had all eight of my sketch or coordinate systems created I'd be able to create all of them in here and then I can go to this individual feature and change the name to what I want to call it in this case here entry 2 and that's good and I have the original sketch that is automatically hidden so that is a way that you can create coordinate systems from a sketch and in this case I'm using it for my entry ports for cabling now let's take a look at another very important use of our coordinate systems and I use them for assembling components especially imported geometry like this so for example let's say that I have an assembly let me switch over to an assembly in another window here I have it's essentially going to be a circuit board here a bunch of other molex connectors and again thank you more let's know in this case this particular one just has an import feature it's not fully featured like the other ones but inside of these individual parts I'm gonna open this up I created another coordinate system that will be used for placing those components and so I know that I have my Z Direction going in this particular direction when I want to use this for component interfaces are to make sure that the other part that's going to use this is going to use it in the exact same way and you'll notice that this part from molex they actually provided three core interfaces for me to use but I created my own custom one for having components assembled to this one so let me go back to that molex connector and so the way that it's going to be assembled in here I need to create a new coordinate system so let's create the coordinate system I'm going to select this flat surface and hold down the control key and select the datum plane called side and then hold down the control key to select this surface so there I have my three references that are necessary let's go to the orientation tab and I actually have Z pointing in the right direction that's using let's see this surface let me check here I want this surface to determine Z I'm just gonna select explicitly but I need Z to point in the other direction that is good and let's choose to use this surface to determine Y so that is the orientation that I want to use for this and for the property since I'm using it to place this component I'm going to call this place and hit the ok button and now let's create a core component interface that uses that coordinate system so let's select it as the reference and coincident and from the placement tab I'm going to make sure that I'm gonna change name I always like to change the names of my feature so I'm gonna call this locate and since it's my only component interface it's automatically going to be used as the default so that is good let me hit the check mark and so now I have a coordinate system and be aware that you don't have to create a component interface in order to use a coordinate system for assembling a component but I like to do that now let's hop back over to that particular assembly alright Here I am back in the assembly and you can see my pattern of connectors over here first off I just want to show you if you go to file options and then assembly inside of here if I scroll down there are a bunch of different options that you have and so for example component placement interface control for automatic component placement use this interface you could choose default here I can change it to from list and we have the place default component interface using I like multiple locations and I'll show you why in a moment there are some other options in here for component interfaces let's click the ok button I actually like that change to the settings I made let's click the yes button to save it to my default config dot profile and now when I am ready to assemble those components let's click the assemble button and let me go to in session and find that molex connector that I am using I'll click the Open button and right now it's using interface to geometry this is the button that allows you to place using component interfaces if you wanted to assemble manually you would use this button over here and instead I want to use interface to interface and when I click that right now it doesn't show me any preview dots there's a little trick if you're using coordinate systems for a coordinate system to coordinate system placements with component interfaces you have to go to the options tab over here and uncheck this option to check in our face interference of matches so let's uncheck that and also now I have the preview dots and so I can select my receiving interface there you can see the preview let's turn off our datum display uncluttered and there that just looks beautiful house being placed in there oops accidentally hit the middle mouse button when I was trying to rotate let's do that again for placing more components I'll hit the assemble button and let's grab that particular component and click the Open button and change this to interface to interface and I'll select this one over here that's good now I can hold down the right mouse button choose new location and the one that I placed turns purple let's click on the other location the one that's active is going to be an orange and again I can right mouse click again cold and choose new location again and then pick the other component interface and that's good I'll hit the checkmark or middle mouse button and in that way I was able to assemble those additional connectors in my assembly using those component interfaces based off of a coordinate system so I'll bet you didn't think that there is this much to know about coordinate systems in creo parametric or maybe you did anyhow I hope you enjoyed this video for more information please visit WWE when show com if you learn
