NX Cam Associativity for non native parts
NX Cam Associativity for non native parts
(OP)
Hello everyone,
I am relatively new to NX Cam at about 8 months with NX8 and 8.5. My background is 15 years of Pro/E & Pro/NC with about 3 years of SolidWorks and FeatureCam.
I work with non native step or parasolid files from Autodesk Inventor. I want to start programming a part that is still in the design phase. Does NX Cam allow me to program a non native part then replace my original part file with a revision and NX maintains or updates the tool path? Up to this point I have done this by importing the rev part and manually repicking all of my toolpath geometry.
Is there a better way?
I appreciate all of your help.
Scott

Response 1) I would use Master Model manufacturing assemblies and WAVE link the imported component up to the manufacturing assembly level. You should then be able to replace the component and regenerate tool paths. Operations that have the WAVE linked solid body will have the best chance of regenerating without any additional edits. Operations that use selection intent also should regnerate without edits. Use of boundaries will probably require redefining those boundaries before they regenerate properly.
Response 2) As Rob stated using the CAD model as a component will allow you to easily replace the component in the CAM assembly.
In addition the use of a linked body allows you to use the replace assistant to handle matching the old faces and edges to the new ones.
The match will also improve maintaining associativity of boundaries.

I get .stp files from v5. Then, once converted to .prt I bring it as a component and make a Wavelink. If the model does not change "too much", I get pretty good results with regenerating operations after revisions. That said, if the dude at the other end deletes features and recreates them rather than moves it, there is always work to do...
Btw, I wished our company got into this habit before I got here. We have cam files with 4-5 parts on different layers with toolpath assigned to all of them! Wavelink is the way.

Bill, can you give me detailed steps on your procedure? I have attempted this process and have experienced the following.
1)Output parasolid 'Toolpath Test Part.x_t' from Autodesk Inventor, for some reason Inventor outputs a metric part.
2)Open 'Toolpath Test Part.x_t' in NX 8.5 save part file which is automatically renamed 'Toolpath Test Part_x_t.prt'
3)Convert to inches
4)Start Manufacturing model using Master Model assembly technique.
5)Create Wavelink to Solid1 i.e. 'Toolpath Test Part_x_t.prt'
6)Build toolpath operations
7)Modify Inventor part and output new parasolid titled 'Toolpath Test Part_2.x_t'
8)Repeat steps 1 & 2 to create 'Toolpath Test Part_2_x_t.prt'
9)In NX select component 'Toolpath Test Part_x_t.prt' MB3 and select Replace Component with 'Toolpath Test Part_2.x_t'
10)Alert : Component is not a version of replacement part
If I assemble 'Toolpath Test Part_2.x_t' directly into the model and select Replace Component I get the folowing Alert: Following Links were broken, Linked body Solid1.
Similar to your experience if the designer in SW or Pro/E deleted and rebuilt references rather than modifying them toolpath regeneration failed and references needed to be reestablished.
Thanks again,
Scott

All parasolid files are metric.

To whom are you posing this question? I as the original poster am running NX 8.5.1.3 NX Cam only. I do not have modeling available to me on regularly. I can borrow it from the other user for short periods if I need to.
