Please help. trying to import cad topo. overload!
-
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. -
How big is the file? id imagine if its a lot of linework the problem is jsut SU doing lots of calculations, id see how leavign it running goes first, then try alternatives later.

Hi Collins,
What Remus says. Sometimes SU just seems to be hanging although it is working.
In another post I remember a guy who let it on for tens of hours until it finished the job.I'D gladly help but my rig is rather poor.

I've done this only a couple of times so I'm no expert. I think push-pull takes too long to calculate the face with that many edges.
What worked for me was to break the closed entities so that they are just lines. Import the Cad file as a flat drawing. Use control-select to select all the individual segments of one line then the move tool to move each contour line vertically to the correct elevation. (I don't know if topography from contours will work if each contour line is made a group, but grouping them makes them easy to move and select. You could make them each a group, move them then ungroup them I guess.) In any case, "from contours" will work from open lines once they are at the right elevations.

there is also a ruby called Simplify contours available here
I have found it very useful.
