I have designer drawings coming from Adobe Illustrator. I need to open those drawings in AutoCAD to make technical drawings. Then designers need to open them in Adobe Illustrator to make adjustments. How can I make these transition smoothly? Because now when I open ai files in AutoCAD, the lines are terrible. I have to redraw every lines. When designers open pdf file I saved from CAD in Adobe Illustrator, there are too many anchor points to edit. Anyone can help? Really appreciated!
