3D topo from contour lines

[tim_m]

does anyone know an easy way to convert contour lines to a smooth 3D suface in rhino? I have all the lines drawn at the depths that they're supossed to be at, but I can't seem to generate a good surface thru them.

Have you tried the loft command?

[kfitz]

Better yet, how about patch?

[kfitz]

Here is Mt. Plywood done with three contour lines and the patch command.

And Mt. Water done with the same three contour lines, the patch command, and then drape.
6953

[tim_m]

I've done simple 3D contours using patch.
But the one I'm doing now has many steps. Maybe my sttings are wrong?

[kfitz]

What version of Rhino do you have?

[tim_m]

I'm working with 3.0

[kfitz]

Does it crash, or just fail? Any error messages? Do you have the latest release? There were some bugs with Patch in early 3.0.

I only have 2.0, so I may not be able to help much. Can you save as a 2.0 and send the file to me?

It just doesn't create the surface the way it should look. I've sent you a dxf to look at. thank you for trying to help

[kfitz]

Did you import the contours into Rhino as a dxf (or something else)? Or did you create them in Rhino?

Haven't received it yet. Try this email:
