Changing the CAD model in an existing Project

[[Sc...]]

I am new to Zeiss Inspect, so feel free to educate me on how to find topics like this if they already exist.

What are the rules and procedure for changing a CAD model when you have and existing workflow built already?  

When I change CAD is there a way the software makes me aware of affected elements?

I don't have the knowledge for this case, but perhaps in some cases it can say something.

Problem to solve is to place new CAD model in same location as old one. Then you would need to edit selection for every nominal element taken from CAD ( select element and press F4, then make new selection on CAD face - patches or lasso )

If you are not sure or you have some ideas to test - just do it and try it yourself.

There is a function that should help you to adapt the elements to the new cad (Adapt Element to CAD). See here for the explanation in the Tech-Guide: ZEISS Quality Tech Guide. Of course it has limitation but maybe it solves a significant amount of elements that you can save some adaptation time.

I can tell you from a lot of experience, when you bring in a new CAD model even with a minor change in the CAD model you need to at LEAST edit the datum features and any other critical features.

I re-find all features, and some of our programs have 500+ features.  Our tolerances are extremely tight so it is mandatory I do so.  Needless to say, on a big program, if a CAD model radius or chamfer changes by .001", I don't import a new CAD model b/c it isn't enough of a deviation that the program is going to grab surfaces outside its intended area. The program is going to still measure the mesh and not the CAD model for outputing measurements, so all is good.  If there is a critical dimension that is changed by .001", or a non-critical that is changed by .005", I re-find all surfaces.  That is a general description for how I re-find features....I am very protective of bringing in new CAD models for established large programs.  If a program is small, I re-find every feature anytime I bring a new CAD model in.

 

When I say re-find...it I edit the feature and it the CAD model is still highlighted in the correct area I close the feature....it is good. But if it has extra surfaces or missing surfaces I correct them.
