Siemens NX 2007 - I can't believe why this is a CAD Secret - Sketch Solver - Half Diameter Dimension

what you see here is the brand new major release nx 2007. i haven't installed the miner yet which is available for a couple of days now but anyway still am able to show you a renewal about the new sketch solver i'm gonna talk about half diameter and a cat secret which maybe was not expected about the new sketch silver half diameter enhancement i'm also going to discuss another topic about sketch creation because there is a modification which i do not like compared to the possibilities we had before hey guys how are you doing this simon from biz learn hi and welcome to a brand new tutorial of my tutorial series annex cat secrets and what's new siemens nx 2007 in that case first of all before i'm going to start sketching i'm going to start the revolve as i mentioned before i'm going to be talking about half diameter which is a solution many people were waiting before because it's much easier to dimension a revolved sketch without calculating and i'm gonna be using the profile therefore and draw well i'm not gonna define length here i'm just gonna define some some width because half diameter cannot be defined from scratch it has to be defined afterwards and i'm just gonna move this point towards my x-axis here we are how can we create half diameters well it's pretty simple you really just have to select your first reference which is an axis and a point like this and what you see here is a typical perpendicular length dimension which i'm going to activate and i'm going to define a value as well and right now i am able to right click this and convert it to a half diameter which is documented well in the official documentary but anyway there is a cat secret which is not displayed in the official documentation of siemens and x because you can go on with the creation of half diameters without converting and there's something you have to regard it's the order of your selection whether you start selecting this one first or the point first so i'm just going to select the point and then the axis and now you see it's a typical perpendicular length but if you proceed with selecting the axis first and then the point you can see it's a half diameter that's the cat secret why is it a secret just because it's not written in the official documentation of siemens in x i'm just gonna demonstrate this again i'm just gonna undo my selection if you select the point first and then the axis it's a typical perpendicular length but if you select the axis first which is also referenced by this half diameter dimension and then select the point it's going to be half diameter i'm going to select the dimension define a value left click and position the dimension and i'm going to proceed here it's just two clicks required no convert required i'm going to select the dimension i'm going to define a value i'm going to left click and position the dimension and as you can see sketch is fully defined it's not required by the way to have active lines here or here you can of course i'm going to finish this the sketch is fully defined as you could see and a solid body is going to be created the profile don't need to be closed in terms of working with revolve another issue something which i don't like a in my opinion disadvantage i'd like to show you is sketch creation i'm going to create a pocket on on this side here and therefore i will need an extrude and of course no sketch has been created yet therefore i will have to use the sketch section dialog with the center mouse button click and now i can define a position which i'm just gonna do i'm just gonna click on this surface everything seems to be well defined as you can see the horizontal reference is my y-axis and the origin point is referenced to the circular edge here which seems to be fine but as you remember maybe you have experience with horizontal modeling already i have published a few videos concerning horizontal modeling i'd like to show you a problem which i think might be interesting i'm just gonna define some values here it's fully defined as well so i'm gonna finish sketch and create the extrude into this direction five millimeters um which maybe shall be subtracted however and now i'm gonna find some details but first of all define um the current feature here so the revolve is going to be my active current feature now i'm going to define an edge blend related to let's say face edges which is okay maybe this could have been a jumper instead it's not important important is the following fact that if i activate the extrude number three again an alert pops up and maybe you don't need to guess what the problem is for a long time maybe you have an idea already the edge which has been used as a for center definement of the internal sketch of the extrude there's no more exists at this time stamp because of the detail we've created here in a lot of videos i was mentioning this problem that if you create references that's what i actually did when creating the sketch for the extrude you should always select the possibly oldest object and that's what i'm gonna try so i'm gonna start the extrude again i've deleted the first result i'm going to start the sketch section while i center mouse button and now think about the problem so i'm first of all i'm going to select the face as usual you can see a horizontal reference is chosen from the datum coordinate system which i think is an enhancement this was not the case in the past and older versions and this is the possibly oldest object and i mean it's not a fixed axis so that's cool there is a relation but the origin point has been chosen from the revolve and it could have been chosen from the coordinate system as well i did a little mistake now so i'm just going to deselect this and select the point from the coordinate system just like this and now the horizontal reference and the origin is well linked to the datum coordinate system which is not display at the moment but that is the case i'm just gonna reproduce the problem with a little circle here and i'm just going to reverse this direction and subtract it and let's create a chamfer now let's use symmetry and five i'm gonna apply this and i'm gonna activate the extrude again and you can see it's not broken just because the internal sketch from the extrude is completely referenced to the datum coordinate system beside the face but the face has not changed yet so how can we avoid problems here how can we create a sketch or an internal sketch without the horizontal modeling problem or the relation problem however i showed you a solution already you just have to select the sketch plane and afterwards select a different origin point to avoid the selection of edges which is usually not necessary another opportunity you have is which i did in the past and this is something which i would call a disadvantage because in the past i have selected the plane and afterwards replaced the plane by the face just because if you select a plane from a datum coordinate system the horizontal reference and the origin point is always selected from this coordinate system and it still is but you cannot replace the face it's not possible in the past it was possible to replace a face and now it's not i think this is a programming issue which should be solved in the future especially when you are thinking about horizontal modeling relations which you want to keep however another opportunity of replacing the face is of course the reattach tool because reattach still uses the same layout as in the past maybe remember in the past reattach and create sketch we're using the same layout now it's different but reattach still allows you to just swap or to just replace the plane or face however and you can see the relations here is still maintained of course because i've just switched plane there's another opportunity within here which allows you to easily reattach the sketches in my opinion it makes sense to use infer again infrared is meaning that you select the plane from the coordinate system and afterwards replace the plane by selecting the face and after doing this two relations meaning the horizontal axis and the sketch origin are still referring to the datum coordinate system only the face and plane were replaced i'm just gonna demonstrate this again i'm just gonna reset this use insert maybe some of you are not on the latest release and still have the opportunity when creating sketches from scratch it's still the same layout use invert select your plane from the coordinate system and then afterwards replace the plane by selecting a face i'm gonna link a video on the upper right because i've already published a video about replace meaning reattach sketch exactly showing this kind of workflow and now we have horizontal relations meaning our sketch is independent from the detail and this is always my target my goal to keep things independent as much as possible i hope you learned something within this video i hope you enjoyed the video i'm looking forward your reactions in the comment section below and of course use the thumb up button if you like the video and don't forget to subscribe
