The danger of working for Autodesk is that everyone assumes you're an AutoCAD expert. Though long ago I worked on AutoCAD R14 with regard to DWF publishing, I am by no means, a Shaan Hurley nor Lynn Allen. Sometimes on a Throwback Thursday, I will wear my R14 shirt. People will approach me on the ferry and ask very detailed questions like: "I am using line style by color in an xref overlay, and my dash-dot pattern starts with dot-dash instead of dash-dot. Why?"
Well fear no more. You can get the answers. We're having AutoCAD Answer Day. Check it out.
Answers are alive in the lab.
