Faking a Roundover in Sketchup

I continue to work on learning Sketchup as a tool for creating my woodworking plans. Last week I posted about the difficulty I'm having creating a roundover on the tensioner of my Inkle Loom plans. I've concluded that "Intersect with selected", while it works in theory, is not the easiest way to do this. Follow Me seems like should be easier, but I haven't learned to use the Follow Me well enough to achieve this.

While browsing Design. Click. Build., I discovered a trick that looks right, even though it isn't: edge softening. For many woodworking plans, this method is good enough for indicating a roundover, as seen in the picture above. Even though the edges on the white tensioner aren't rounded, they appear to be. The lack of rounding is only evident at the corners: notice the rounding of the back corners on the blue tensioner, and the squareness of the same corners on the white tensioner.

Here's how this fake roundover was accomplished:

1. I drew a new tensioner without the round edges. This was easier than trying to remove the rounded edges on the first tensioner.
2. On every face I wanted to look rounded I used the offset tool to add an offset 1/8" from the edge. This gave a stopping point for the softening effect I planned to use.
3. Using the Erase tool, I softened the edges. To do this I positioned the eraser over an edge that needed softening, pressed [Ctrl], and clicked the Eraser on the line. This hides the line and softens the edge
   
4. After all the edges were softened, I used the Select tool to select the offset lines, right click, and select Hide.

The results are good enough for my application, but I'm going to keep working on edge rounding until I can apply a real roundover if I ever need it. Many thanks to Dave Richards at Design. Click. Learn.!
