I did a Sketchyphysics model of a 9mm Luger cartridge so I can simulate the functioning of various firearms which use it. The biggest problem is: None of the parts seem to recognize seem to notice the others and just pass through each other.
I MUST be missing something very basic.
I'm not typically importing anything in SU, so I'll give you some numbers based on a mechanical drawing I'm doing.
I'm running SketchUp 7.1 under Linux/Ubuntu/CodeWeavers-CrossOver. My machine has 4Gb of memory, of which I'm using about 1/3rd. Video is 512Mb, and I have no idea how much of that memory is being used.
The file in question is 4.7Mb and was created entirely inside SU. At this point it has started losing entire layers spontaneously. I have no ideas how many faces it has. There are no textures. There are in excess of 20 layers.
I'm using Sketchup to do mechanical drawings, and the size of my files is inconsequential compared to what you guys are doing. I currently have 2610 edges, and 1372 faces.
I have 22 layers in use at the moment, but that seems reasonable considering that I'm doing a mechanical drawing. If 22 layers is a problem, perhaps we need a fix.
