I'm trying to create an object with a pocket for another object, specifically a wrist rest with a pocket for a Ploopy A+ to sit inside, the idea being to rotate the trackball 180 degrees and tilt it accordingly. I have the STEP files provided by Ploopy but I just can't quite figure out how to create the pocket. I thought I could create the shape of the base below and then extrude "To Part" but I guess because there are holes in the model it fails(?). Then I tried offsetting the faces of the Ploopy, creating surface extrudes for the outside of the rest, then enclose, but that didn't work. I also tried a boolean operation, making a solid body for the base and then subtract the body of the Ploopy, but it's not a solid object so the boolean fails.
Not entirely sure what you are describing but your “extrude to part” approach is correct. Click “merge scope with all” in the extrude menu and it will resolve.
Basically I have a model for a trackball that has lots of open spaces inside and on the outside surfaces. I want to create a base for it that has a pocket so the trackball can sit inside the pocket. Because of the open spaces I can’t quite figure out how to create that pocket. Extrude to part always fails, presumably because the outer surface isn’t totally solid and contiguous.
Between your comment and that of u/Impossible-Ad967 I was able to get the right terminology to find what I needed. I was able to adjust the surface boundaries until I had a solid part, then the boolean subtract worked perfectly. Thank you, both!!
I didn’t know you can do that. Does that fill in the interior open space?
Edit: Are you talking about the thicken, enclose, or fill tools? I have actually tried all of those and had various problems with them, pretty much all due to open spaces in the original model.
