I've been doing some machining tests and realized there seems to be a visual bug when using a center line full-depth route. 

When a route is set to center tool compensation and full-depth, the 3D part shows the cut following the inside of the route, rather than the center. If it doesn't go full-depth, it shows correctly.

I created some identical routes set to left/right/center compensation and using offsets that should allow the output to be the same. You can see from the screenshot, the center line full-depth cut is not displaying correctly on the 3D part. These are all using the same 0.5" diameter tool.

Just wondering if anyone else can replicate this issue, or if there's something wrong with my settings/tool file.
