I have a fairly complex model that keeps generating multiple surfaces out of a single completely co-planar surface. I think it happens when I move parts of the geometry along a single axis. All geometry is on layer0.
I don’t see how to attach a screen shot, but basically a flat surface gets subdivided along a particular line. There is no line object between the surfaces, and everything is completely co-planar. All my objects are designed to be cut out of 1/2" plywood, so they are basically 2d objects 1/2" thick
If I try to repair by control-pushing the other side (which is technically identical) it will end up removing the surface I push (!!) but NOT the others.
It’s happening so consistently I’m getting very tired of the only workaround I have found, deleting all the surfaces on one side, (sometimes there are a dozen or so, along tongue and groove lines) and then ctl-pushing the other side to restore the object.
Sometimes I can reduce to 2D by pushing, and then the lines between surfaces get ‘called into existence’ and I can select and delete them and then repush back to 1/2" thickness, but other times the object just disappears. How does sketchup decide whether to remove geometry when you push an object down to 0 thickness?? It seems completely random.
Thanks for any suggestions.
