Material region: Is this a known bug or am I doing something wrong?

[GeneDavis]

I'm about ready to send in a ticket, but first, let me present it here.

 

On the outside of exterior walls, I am using the tool to do some board-and-batten accents on gables.  A view of the house is attached, plus a zipped up copy of the plan.

 

All worked well for the upper gable.  For each gable, the boards that surround the field and battens are done with p-line solids.  I used the material region tool to do the 1/4-inch thick field panels and the battens that face them.

 

The tool worked as expected for the upper gable, but for the one at the end of the extended eave shed, the tool would not produce the battens.  It is easy to reproduce the error I got.  One selects a batten, converts it back to a polyline, then tries to use the material region tool to get the effect.  You'll see the bug in action.

 

My workaround worked, 'cause that is what workarounds do.  But am I missing something about this tool, which I have used very little?

The Material Region for the Battens should not "Cut the Finish Layer" of the Wall.  For the Corners, use Corner Boards.
