My model that I uploaded from a step file is disappearing while I am trying to edit the check pattern. I'm adding a series of points along a curved radius and then making that into a constructed feature circle and then its just making the model disappears when I go to read a dimension from that constructed feature.
Don,
I've had this also today.
Editing a program and the CAD model disappears. I checked the CAD Assembly and CAD levels; nothing is showing.
Had to re-import the step file.
