I have yet to find a clean easy way to use a DWG 2-D layout drawing as a reference for creating a layout. I design processing equipment for the biotech and pharmaceutical industry. Our equipment is getting bigger and more complicated and we need to integrate with more existing equipment in facilities. The issue that we run into is that we receive facility layouts in DWG/DXF format. The way that I have been working with them for the past couple of years is to import the DWG as a new sketch in a new part. Then I use that part as my layout reference. The sketch that is created usually has 1000's of points and lines. Seems to be much more cluttered and disjointed than when if is viewed in Draftsight. This sketch/part usually brings my system to a halt and is very hard to work with. Is there a simpler way that I can use a DWG/DXF as reference layout that will not crash my system or take hours to work with.
