Sculpt box with square bottom and circular top

stuart_rubin — Sat, 12 Dec 2020 04:17:39 GMT

I am new to the "sculpting" environment. I am stuck on what should be a very simple thing. I would like to construct a box that has a square (or really a rounded rectangle) bottom and a circular top. I am sure that with a enough pushing and pulling the form I could get it, but I suspect there is a much more elegant way to do it.

How can I force the edges at the top of the box form to be a circle (or any arbitrary shape for that matter)?'

Thank you!

It's rather simple in solid modeling: Loft and Shell

@etfrench yeah, but to make ot resemble the look of a Sun-D or T-SPline model it'll take considerably more work than your attempt.

@stuart_rubin there might be a way to do this by extruding a subdivided cube andthen us eht "Match" command to try matching the top to a sketch circle, but I used Blender for the stuff below as it has specifica function for this in the Loop Tools.

Just add fillets to the original sketch😀

And a couple more lofts with rails:

It's fun to play with this type of shape. They would be easy to 3d print or make with a 4 axis CNC, but I still haven't figured out how to do it on my rose engine.

Thanks for everyone's help. I think the "match" command was what I was after.

Can you post your version? I'm curious to see the differences between the modeling styles.

Actually, the match command isn't needed at all. I don't know what I was thinking, but this is very easy to do.
