Hi guys, I started to test xGen a little while ago and I had some questions...

I modeled the structure, ceiling of a shed, but when it comes time to remove the volume of the rectangles and the wall to form the windows, it does not work. Apparently when I zoom in, you can see that the material inside the wall has been removed, I tried turning off the visibility of some operations, but so far I haven't found the solution. 

I would be very grateful if anyone has any tips to give me.
