why does model disappear when trying to add blends?

I am using Creo direct modeling 19.0 and have a model of the thermoform tray with several cavities.  When I try to add a blend to any one of the edges, the model disappears.  Sometimes, in the structure tree, several copies of the model show up, but the screen is blank.  I have tried using constant and variable radii.  I cannot using extrude cut with the corner fillets in the 2D, because that yields a cone, because the cavity walls have a draft angle.  Also, almost every modification I make on the model turns it into a face part.

Sharon,

I'm not sure how to advise without seeing the object. Can you please provide a few screenshot of the model or the file itself?

Sorry, but I cannot share a photo, since the model is proprietary.  But consider it something similar to a seedling tray for plants.  The depressions have sharp edges that need blends.

I guess HP is under Support.

If so, you can log a Case with PTC Support and mark it as NDA - then PTC will initiate a very strict process

which guarantees that your data is kept proprietary.

If you are in assembly mode try config option - dim_inactive_components - (ref Creo 3.0 )

Yes more info will help, are you 3D or 2D?

Good hunting,

Sharon is using Creo Elements Direct, NOT CREO.

Sometimes it helps to export such a part as IGS and then import it again with high repair level.

What is the resolution of this part?

Is the radius eventually bigger than the wall thickness?
