Hi all-
Excuse me if this is a really naive question, but I havent figured out a way to extude an arc in 3d without getting it to turn into a large piece of pie shape. To explain-
The shape I am building is essentially a long thin box, but one half of it has an arc to it. So, there is a gentle rising arc (vertex is below) then straight across. That linear shape is the same on the bottom, and the endpoints are capped off with a straight line.
Now, this all draws out just fine. But if I got to do a 3d extrusion, instead of extruding just the arcs, it also extrudes lines not previously there, which connect the ends of the arc to the radius. So now my thin shape with a slight curve on one side has a large triangular shape hanging underneath it.
I am new to VW (being an autocad transferee) so I am positive I must be doing something silly. But I just cant figure out what. Shouldnt the arc just be... the arc itself? And not include geometry related only to its creation? (since I niether drew nor can even see the new lines it pops into the extrusion.)
TIA everyone, really.
BTW I am on a PC version 9.5.2
And looking to get up to ver11 soon as I can swing it...
