Re: contour type im****t

actually think I answered my own question.  I found a tool that will
convert the autocad contour plot to X, Y, Z data (for free) and this
resultant file is usable by the scan im****t tools.  these tools also
provide methods to map a surface through them.  So it looks like I am
able to get a 3D surface for my uses with just a few hours processing
time.  Hey I am working with half a million points.....so I wouldn't
expect it to be too fast.
