Curve on surface?

Thanks Ambi, I'm glad that you like it!

In general, I don't think that there will be very much advanced surface tweaking functionality at least in the V1 release of MoI, it's more focused just on covering the basics right now.

For curves, you can add a crease in the curve by doing Edit/ Add pt, and checking the "Make corner pt" option. The point that you add will form a sharp crease in the curve if you move if around.

I don't think that there will be a lot of the types of tension/continuity type tools in the first release.

Also something that probably won't come about for a while. It's kind of a complex area - if I just do a simple one-point object snap to a surface, it could be a bit confusing since for example if you had a sphere and drew a line with just the endpoints snapped to the surface, the line would not flow along the surface of the sphere, it would pierce through it. Doing a full-out actual draw each type of curve (lines, circles, polygons, etc) on a surface where the curve flows along the surface will be quite a lot of work, so it will be a while for that.

This one I think I will have, maybe roughly within the next month or so?

> 4. How about the ability to refine curves and surfaces?

You can do local refinement of a curve using Edit/ Add pt right now. This doesn't work on surfaces currently, I'm not sure if this will be done for V1 or not, it's kind of up in the air right now.
