What is the best way to bring TIN-ground to level with buildings? I tried to draw extra TIN-lines and move up, but the results are not good. I've also tried thomtoms vertives tools, but I can't get it to work.

Hmm, maybe I didn't say it correctly..

Ok! And which plugin can make slopes on both sides of the road? Ground elevation I mean.

What is the best way to create faces/triangulate from edges.

Hello,

Is there a plugin which enables selection by drawed line?

I mean that can I draw the selection which chooses groups, components, edges or faces. Just like lasso tool in Photoshop? This would help me a lot, thank you!

A question about road intersection with ramps.

What would be the best/easiest way to make faces for the ramps?
I managed to get face with sandbox contours, but what about any plugins?
See the picture.

Slope down, for example for some area. So all the vertices could be on same level on that area.
