I am new to Rhino and have been having fun digging into it. This one simple task has been haunting me. Building some cabinets. Extruding simple boxes is great but I can’t seem to join these lines to this square to extrude the section at different heights.
Hi Molly -
From that picture, it’s impossible to tell what you have and what you want the result to be.
Closed curves, such as a square, can’t be joined to anything else.

you need separate rectangles like so. you may have to split the curves and rejoin or simply draw a quick closed polyline over the existing lines, which is usually the fastest method.
I drew a square then added the 3 lines. I want to make a piece of wood with a miter. I want to extrude the center square up 3/4" then combine the three squares on the perimeter and extrude them up 1/4’. Coming from SketchUp where I would just pull it up.
Hi Molly -
If I understand that correctly, you are starting with this:
With what you now have, the easiest will be to use CurveBoolean twice to create two different curves:
Then select one of those and either use ExtrudeCrv or the Gumball to create the desired extrusion, and do the same for the other curve.
In Rhino 8 there is a test command (TestPushPull) that goes a little step into that direction. You’d need to turn the square (the black curve) into a surface (PlanarSrf), and that test command would then allow you to just pull up the center part of it. For the other bits, you’d either have to perform that operation 5 more times for the different areas, or start from something like this:
But, again, that’s only a test command in the Rhino 8 WIP.

You can extrude lines(CRV) But you’ll just end up with planes. You also need to select your lines to join them _join. You’d be better off turning on your end points and smart track to ensure your lines are connecting, then use _PlanarSrf to turn your middle rectangle into a surface and then _ExtrudeSrf to pull it up into a box.
Easiest way to create a box is _Box.
