CAD model display issue

[[To...]]

I have one program built from a STEP file, that whenever I open the program, the model flashes for split second and then goes away.  I go to CAD > View > Re-draw CAD model and I'm good for the rest of the session.  If I switch a window over to another measurement plan and come back, I have to repeat the re-draw process.  The icons along the bottom do nothing.  I've created a new MP with the same model and it happens again.  I've healed the model, no difference. The STEP file is 3,590KB so I'm not sure if it's a size thing.

Does it have to be a STEP file. Have you tried saving as a .SAB. Or try re-opening it in SolidWorks and re-saving.

Is it an assembly with multiple CAD entities inside the .stp file?  I agree with Clarke--try saving as .sat or .sab and then heal the model if feasible.

Perhaps this is a red herring, Tom, but
1. Did you save it after you re-draw it.

2. If you look in the CAD hierarchy (CAD>Modify CAD entities and then go to the Hierarchy tab), is the CAD model perhaps unchecked in there?

From Calypso, I saved the model as my model.sab.  Then, I deleted the model within program.  Loaded the new version of the model. Re-associated the features to the new model via CAD Comparison. Closed and restarted Calypso. Loaded MP and the model stayed active. 🙂

Thanks to all.
