Hello SW user who are now in FORUM Hell! I am trying to figure out why in a Part that has multiple pieces or segments I can some time suppress a handle or knob or what ever and some time when I do the Whole part disappears? I am trying to break a model down into 3D print size parts. I want to suppress or hide the other sections of the model so I can save only one portion to 3D print. Right now sometime when I suppress something, the entire model disappears. Sometimes when I hide something the whole model disappears? Any suggestions and or point to a helpful tutorial will be appreciated.
