Rounded Box? (by Bill Richman)
First of all, I'd like to express how much I've enjoyed working with SolveSpace to make parts on my 3D printer, and offer my sincere gratitude to the people who created and maintain it. In a time when most new Windows programs are orders of magnitude larger than my first hard drive, doing this much in a single executable shows how it should be done!

My question: I'm trying to make a small control box with rounded edges, and I can't quite work out how to do it (if it is indeed possible in SS). I draw a rectangle, create tangential curves at the four corners, and extrude that. So far, so good. I have something that looks like a can of spam. Now I want to round off the top edges as well, and I just can't work it out.

I've tried creating a new workplane at one end of the extruded cube (both at the actual end (which isn't allowed, apparently because there's no actual "material" there) and at the level where the tangent lines meet the edges), drawing a rectangle on that plane, and then adding tangents and extruding it. My results have varied, but have all failed in one way or another to produce the desired shape. Any help would be appreciated!

There is currently no way to change an extrusion beyond editing the base sketch. You can create more parts, but there is no way to modify an extrusion other than doing boolean operation on it. You might try drawing the profile you want in sketch aligned with a different axis, then draw a rectangle around that, then extrude - difference to cut that shape around the part you already have. repeat for the 3rd axis. But this doesn't create spherical corners which you may want. An assembly may also be an option. Others may have better ideas, but you have run into the limits of what SS can easily do.

you can start with this ...
