Extrusion fo Srf?


(Chris Kuether ) #1

I find the behavior of making extrusions annoying. I was expecting a ‘normal’ srf.

Is there a command to make the extrusion into a normal srf?

Hi Chris- use ConvertExtrusion, and to stop making extrusions altogether, run the UseExtrusions command.

Thanks Pascal. I knew it was there somewhere.

So much new to learn.

Is there a problem that extrusion objects cause for you? We worked hard to make them operate as if they were surfaces or solids - did we miss something?

Unimportant; learning curve items.

In Rh4 I would extrude a circle [it would not be capped] then turn on
points, select one end’s points, scale2d to make a tapered cylinder.
The extrusion differs: it’s capped, shows only 3 control points.

Learning curve progresses.

Thanks for your interest.

I’ll be back…

Well, you can extrude uncapped, just choose extrude curve from the surfaces menu or click on the command line switch solid=no… But no, you cannot play with the control points of an extrusion the way you describe. What you can do in this case is use Gumball and sub-object select (Ctrl+Shift+Pick) the edge (after extrusion), then scale with the Gumball handles or with Scale; or just use ExtrudeCrvTapered to make a tapered extrusion.

Proper meshing. http://discourse.mcneel.com/t/mesh-aspect-ratio-not-used-when-meshing-on-extrusion/
