I've been using Draftsight for about a year and I've never had this problem before.  3 weeks ago, I re-installed Draftsight (computer problem) and now I can't print volumes / 3D parts correctly.

When I open the file everything looks fine but when I print or do print preview, multiple lines appear on my part, like facets, making it difficult to comprehend...

I know it must be a simple setting I'm not getting...  Can somebody please tell me where to change it?
