Hi,

We are working on modifying a sheet metal tabletop to have holders for rollers.  Rather than create a pile of features and details, I decided to create the profile for one roller, and use a sketch-driven pattern to place the rest, like below:

However, Solidworks is having issues with this.It says "Cannot find matching edges/faces on the body to apply mirror/pattern of this Sheet Metal feature".

The feature tree is as follows:

Extruded Cut to make opening in top.

Edge Flange to make the tab.

Extruded Cut for hole through the flange.

Mirror @ Plane 1 to mirror flange on other side.

Does anyone have advice on how to make this work?
