Hi!
Trying to get the level curves from an Autocad file (3D), I have imported a .kmz file made from the .dxf. The import took a very look time, because each curve is made of… tens or hundreds of thousands of vertices. I have two questions:

How can I actually know the number of vertices of a selection? For example I did a loop selection (alt+B) of a whole level curve (it took 10 seconds on a G5 dualcore!) and I would like to know how many vertices it is made of.

How can I simplify the curve? The equivalent of a decimator, but for curves. Does such a tool exist? I guess I could use the random selection tool, but there is a risk ok removing some actually important vertices?
Blender is great by the way
