I'm trying to draw a sloped window using Roof By Extrusion with Sloped Glazing. When I finish the sketch, the centerline of the entire sloped glazing assembly is offset 4 inches downward (parallel) from my original extrusion sketch line.
Does this have something to do with the grayed out "Thickness" instance parameter on the Sloped Glazing type, which for me is showing 4 inches? Normally this is the thickness of the roof assembly, but on Sloped Glazing I don't see a way to change that.
