You can show the draft in a Colored Line Mode using the Model Colors of the 3D objects:
So if You already have defined Your wanted colors in 3D document, You can show them
Thanks, I've never used that tool. It's ok but like you said, doesn't apply color to edges. Edge painter will work but is too laborious having to select every line segment. I wish there was a color option in the properties/display tab that would let you color the whole part in one setting.
We used to have to do this regularly for certain customers. I finally broke down and wrote a macro to do this. I called it DraftPainter. It turned out to be pretty handy. You select the color from the dialog, set how you want the utility to process the views, then just pick an edge of the part to be updated. This was written many years ago (Pre-ST) so use at your own risk. Hope it still works...
