Here's what I've done to get those line extensions you see in SketchUp into a Revit view. It gives it a bit of a sketch-y look that may be more appealing to folks. Yes, this requires a pro version of SketchUp.
1. In Revit -- Export Revit view that you want to make sketchy to a .dwg
2. In SketchUP -- Import the .dwg into SketchUp
3. Still in SketchUp -- Export a 2D Graphic. In that dialogue box, select Options in the lower right corner. You can make adjustments to the line extensions here. I would suggest 2 to 3 inches at first, then you can adjust. Leave all the other options on the defaults.
4. In Revit -- Under the Insert tab on the ribbon, select Link CAD. Link in the .dwg you just exported out of SketchUp. Make the line colors black and white. All the other defaults are okay. Place this linked file on top of your Revit view, aligning the line work. This may take a little finessing with more that one view. At this point you should seen the line extensions.
5. In Revit -- Adjust the line weights using the Override Graphics in View -> By Element for the linked file. Select your line weight and adjust to suit.
You'll need to do this for every view that you want to give the look to. Hope this helps someone. I was pretty happy with the results and it only took a few minutes.
