Here's a great post from Brandon at BIMtionary. He's only done 6 blog posts, so maybe you can all visit his site and pressure him to make daily blog posts.
So the next logical step would be to use the Split-Face tool to split the wall face at the reveal location so you can have multpile faces to paint. After further investigation and frustration we see that when we select the wall face to split it, it automatically has the reveal edges assigned as a face border - so we can't split our faces along those lines. Now we could offset our split-face lines a teenie bit off the border lines but that would be cumbersome and annoying.
Well While going through this I discovered an long standing bug in the software, try this:
- Use your Split-Face tool and pick the wall face you would like to Paint.
- Split the face of the wall anywhere, I do it in a top or bottom corner and create a tiny 1/16"x1/16" wedge (Figure B). Select Finish Sketch.
- Now you will be able to pick the individual faces of the wall created by the reveal (Figure C).
