Awesome that was it. I had to change it to inches.

It is inherent in Sketchup (as I understand) not to tolerate an extreme number of points, which when connected become faces which are called poly's. A total station has no problem generating a large population of points. Sketchup has a problem if it has to make faces out of all the edges that the points potentially represent. Not that it can't, but big files become cumbersome.

I've been trying to use the same plugin, now located at http://rhin.crai.archi.fr/rubylibrarydepot/plugin_details.php?id=292 after correcting the spelling mistake calling delaunay2 when the file was called delauney2, it loaded correctly. however, after trying to triangulate points in SU8 Pro the following is printed in the log Error; #<NoMethodError; undefined method `position' for #<Sketchup;;Edge;0xa726168>> C;/Program Files (x86)/Google/Google SketchUp 8/Plugins/points_cloud_triangulation.rb;63;in `points_to_array' C;/Program Files (x86)/Google/Google SketchUp 8/Plugins/points_cloud_triangulation.rb;61;in `each' C;/Program Files (x86)/Google/Google SketchUp 8/Plugins/points_cloud_triangulation.rb;61;in `points_to_array' C;/Program Files (x86)/Google/Google SketchUp 8/Plugins/points_cloud_triangulation.rb;101;in `triangulate_points' C;/Program Files (x86)/Google/Google SketchUp 8/Plugins/points_cloud_triangulation.rb;133 can anyone help? thanks
