something odd happens when I extrude the end surfaces of the solid in this file. I would expect that I would end up with another solid of the same height and width. However I only get a four sided open polysurface. Also the end surface that I extruded loses its isocurves.
The original solid was the BoundingBox of a irregular solid.
@John_Brock I was using Extrude Face from the solid editing toolbar. As @BrianJ points out there is a Solid option which I missed, although I would have thought that in the solid editing toolbar Solid should be the default. But I should have checked the command line.
Here is a screen grab of the isocurve anomaly. It isn’t a problem, just strange. Thanks for your time!
Yes, @BrianJ, I should use Gumball more than I do. Trouble is that I’m an old dog, and it’s a new trick.
I was able to do it but perhaps I should ask about the steps:
-Ctrl+shift = sub-object selection?
-Move uses arrows? Actually that’s obvious!
-Alt = turns whatever operation you are performing into a copy? Not just move?
-Ctrl at the end of the operation = turns operation into a solid? From my experiments this only seems to work with move?

Correct, cmd + shift if you’re using Rhino on the Mac.
Correct
Yes, it makes an extrusion. This works when moving a surface but will also work when rotating or scaling a curve. I generally only use it when moving objects.
