Hi, long time no write,
As of now auto intersect check is (apparently) performed after each edit operation that can potentially create a topological connection (i.e. checks for vertices coinciding, with edges and vertices, edges with vertices, edges and faces etc, after each location change operation).
During 3D location change operations (move, resize, rotate, explode) I would like to be able to avoid Sketchup doing its automatic intersect operation. The check for vertices and edges and faces interacting with other similar objects is a computationally expensive operation, and it takes too much time for large mesh(es). Funny thing is Sketchup can not perform this operation properly anyway (it sometimes misses connections (one might argue it is impossible to do this perfectly)) and even create unintended connections (during a rotate when two meshes overlaps sometimes two vertices get too close and you get unintended connections).
Auto intersect "on" option would keep the current behavior of Sketchup, If the user is does not want/need new topological connections during a location change operation, this option would be turned "off" giving a faster and cleaner operation.
This issue came up during Tgi3D 64 bits port (which is now awailable), we were discussing what would give skethup a boost.... (we were expecting more from 64 bit Sketchup)
Thanks,
