Thanks, I'll give that a go as I have another set of these to create. For the one I was working on I did create another SketchUp file and as I made the pieces I copied them into the original drawing and deleted them from the one I was using to create the pieces. This was much more stable. I'm sure that there are some small spaces that are causing the issue. Thanks again! This tool is amazing!

Thanks for an absolutely amazing plugin. I've just started using it and am in awe.

I am having one problem though... I'm trying to create a rather complex shape and have found that the only way to do this is by using EEby RailsByLattice bit by bit to create the shape (a kind of circular undulating canopy, if that makes any sense). My Profile is a straight line divided into 14 equal pieces and combined into a polyline. My rails are both polylines with 5 equal sized segments in a curve (they are not identical, one rail is shorter and creates a taper for the circular shape). The melding profile is another straight line, 14 equal segments and combined into a polyline. At first I had no problems. Then making the third one my computer made it through the entire process with no problems and then SketchUp crashed immediately after clicking "no" to "erase original curves." No biggie, I save often. Problem is that it is happening more and more. I've made 10 of these shapes (though no two are identical) and now it crashes multiple times for each one that I do. Always at the same point. I'm afraid to click "no." Do I have too many faces for SketchUp, or am I doing something wrong?

Any help on this would be great. Thanks!
