Currently I have encountered this issue several times when making Revit families when using void extrusions. If you look below at the second image when I am trying to extrude through other multiple extrusions if I have my extrusion start at 0' it will only go through 1 extrusion. But if I have it set to -1" it will go through both. This is the first interesting bug that I found. The other is when selecting a void extrusion inside of another void extrusion it will lead to the larger void extrusion to close up visibly like in the first image. I do not know if any other Revit users have encountered this, but I thought it could be something that could be fixed.
