Hi, I'm trying to import a large IGES file. The problem is that it takes SWX 30 minutes to read in the file. And when it does it consists of thousands of separate surfaces and slows my machine to an unacceptable level. I have used Pro/E for similar tasks in the past and it only took a minute or so. In Pro the file comes in nice and clean as a single solid. How can I do this in SWX 2006? TIA MT
