Defining surfaces and other new questions....

Ah, got ya! Ok. Finally just clicked what I think you're trying to build.

You've almost got it. Here's what you need to do:

- Do as you are presently, and make your four-point polygon
- Subdivide three times
- Make sure your curve is as you want it, then click Object > Commit Subdivision
- Under surface type, click Poly

That should give you a tear-drop shape that's filled in... since it was a polyline not a polygon, you don't need to use create convex object because the surface already exists.

[EDIT: little clarification since I know we've been talking about creating surfaces all along... if it's just a polyline, not extruded, it's effectively a 2D shape. AC3D allows any number of sides in a surface, so practically any 2D shape can be treated as a surface. If your shape was 3D, you'd like need to use convex shape or ordered surface to fill in the surfaces. I hope that makes sense, I don't think I'm explaining it very well.]
