Hi,
I'm trying to import a CAD file with topography lines, (all closed entities), no xrefs, no images, very bare bones linework. I've gone thru the sandbox tools on "from contours", explode, etc. I also downloaded the "simplify contours" ruby script to minimize the eventual overload of my sketchup model. I cannot seem to get past the point of "from contours" before the whole program crashes and goes into the "not responding" mode. I just need to be able to push pull my elevations to the correct height and then stamp the villa floorplans on top. I need this model for a visual study model to determine view corridors, etc. Can someone please help me in any other troubleshooting scenarios. I am happy to send the CAD linework as well if someone is willing to work with it a little. (If so, let me know what version of CAD you accept, and i'll etransmit it to you). I fear that there's just too much information in the file that it continues to crash. I will try running it overnight to see if it just needs tons of time, but I've had this problem in the past and went thru several troubleshooting exercises, to the point i had to email it to one of the sketchup team members to figure out. Even then, the system just couldn't handle the data. I have a Dell Precision PWS690 with 2.75GB of RAM. I'm working in SketchUp Pro 6.0. Thanks.
