XP Professional DP2 Precessor AMD 2.19 GHz 3.25 GB RAM I'm constantly getting Out of Memory errors when building up 3D drawings from IGES and step files. The computer has been checked and experts say that it must be CAD Process that is not handling memory efficiently as the computer has plenty of power. My 3d CAD process file has only reached 250mb in size before I get the memory errors, though it often loads 3d drawings of around 1GB vefore errors appear - it is not consistent, and if I exit CAD Process and start it again, it may load a drawing that gave an error before. A previous post mentioned a setting that can be applied somewhere, but no more was posted about this. Is this likely to be a solution and if so, can we have it please?
