How to extrude a core wall

Rhino Rhino for Windows

I have drawn two 2D walls from Autocad and imported into Rhino as attached.

How can I extrude the more complicated one into a solid wall.
Thanks

Ken, Check out the Gumball functionality as well. Note that extruding a surface and polyline via gumball give different results (closed vs open)

Hi Pascal,
One more question please, how can I transform the smaller 2d wall to a surface and then extrude to a solid wall.
Thanks

first run SelDup in the command line and remove the overlapping curves.

Then select the curves and Join, you should get a closed polyline.

Then run PlanarSrf command. (available on the Surface>Planar Curves as well)

I want to draw a door opening at the smaller wall. I have extruded a solid to intercept it to the wall.

How can I make a door opening in this way?
Thanks

Hi Ken - your extrusions are all open -

Rhino does not care - that is perfectly valid but I suspect you want them closed. The more complex shape will be closed if you extrude the base (red) surface , the other one can be closed with `Cap’

Then, a BooleanDifference or WireCut can make your opening:

Cap is very good to form a close surface. However, I want to extrude to a solid wall. Can I do it?
In Rhino, is a close surface equal to a solid?

Hi Pascal, thanks a lot indeed.
Now I have drawn a wall system and one slab polysurface. I have created a wall layer and a slab layer.
I want to change the slab to green color as the setting of of the slab layer but unsuccessful. What should I do?
Thanks a lot.

Hi Ken -

Yes.

With simple shapes such as walls, you can sub-object select a single surface in a polysurface and move that.

With the slab selected, in the Properties panel, change the Display Color setting in the drop-down from “Yellow” to “By Layer”.
