I just recently found out about Joint Push Pull from SketchUcation. It’s a free extension that adds thickness to faces. Select faces to joint push/pull, then click the blue icon with the J. Click the face, then type in the thickness.
OK, so I’ve watched the video and downloaded and i still cant get a uniform thickness with flat tops and bottoms. I’m ending up with an angled face at the top ??
Yep. When JPP offsets the faces, it “welds” the edges together. This can cause weirs, sharp angles at the edges. If you are looking for smooth, horizontal edges, you may have to move some points or use a plane with the Intersect command to get your final geometry.
when you open the fredo jpp tool you will need to click on the blue arrows (just above the green ones at the left)
This will expand the menu (that used to be present in earlier versions - per the video you saw) In here you can check the yellow “z” axis box which will constrain the push pull to that “plane” only. This should move all the geometry out wards on the x,y plane and NOT move the geometry in the direction of the sloping surfaces. select all the faces and do the move, you can type the amount in the VCB.
