I'm having trouble coming up with a good and easy method for creating models for dual extruding. I want to take an existing part that I designed and cut it up into different sections. I've tried using the wrap feature, but for some reason I can't save just the part that I cut out. I have to save two separate body's as STL's for dual extrusion.
I've attached the part that I'm trying to make a design onto. So far the only successful way is extruding "cut" from front face to outer edge of cylinder, then saving as STL. Then, extruding boss to outer edge and deleting the rest of the cylinder and saving.
How would I model this?
