Question
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.
