Can PushPull extend a tapered tube? Say a tube has a diameter of 10mm on one end, and 15mm on the other, and I’d like to extend the tube till the dia is 20mm. Is this something that can be done with PP?
You need the extend option in PushPull for that, and no, at present the side surfaces have to be planar for the extend option to be offered. So it works with a truncated pyramid, say, but not a truncated cone/tapered tube.
Note though, you can use _ExtendSrf to do what you want.
