Inserting Wooden Dowels and having issues making a simple feature 'easy' to insert, pattern, and mirror as it is a very common compoent in our models.

With new CAD/CAM software being implemented (Router CIM), the old way we have been inserting dowels causes issues downstream. The dowels cannot be merged into the part or the CAM software wants to include the dowels.

I believe we have come up with a solution that works, but gets us to the 1-yard line.....ohhhhh so close! I have created a library feature part that allows me to easily insert the dowels w/holes in the part as a multibody part. The issue comes when I try to mirror the LFP and get the following errors:

SW can mirror in assemblies, create LFP with multi-bodies, but can't do the above? Any ideas would be greatly appreciated!
