Default Re: Joining surfaces

Combining is for polygons. To make that shape, you'd use the top and bottom semicircles and join them to a rectangle (not lines). It's not the easiest way to make that shape. Before combining, you'd need to put all the surfaces in a single object with Object->Merge. You would also need to make the vertices shared/optimized.

The easiest way to make this shape would be to select what you have made and use Vertex->Create-Convex-surface-object. That will create a single surface in the outline of the shape of the selected vertices, which you can then drag out of the way (and delete the originals?).
