I'm trying to make a low sloping roof with exposed rafters. The roof is a single layer of 5/8" plywood, and a beam system. The problem is when the roof is a 1/12 slope, I cannot set the Construction Rafter Cut, Two Cut - Square, Fascia Depth to less than 9/16", or Revit will delete the roof. If the slope of the roof is increased to anything steeper than a 1/12, this problem does not happen.
Therefore, I cannot get a true square cut at the low end of the roof.
If the fascia depth is set to something to get a square cut, Revit cries.
Am I missing something, or is this more Revit B? TIA. mpp
So your roof assembly is only 5/8" thick or 5/8" + the depth of the beam system?
In Roof Construction, Rafter Cut, there're 3 options. The first is Plumb Cut, and it has no setting for fascia depth. The end of the roof profile is simply cut plumb. Very nice and easy. Why the F can't Autodesk make a Square cut be as simple and easy, without having to add a fascia depth dimension that's greater than the fascia depth just to get a square edge profile. ARRRGGHHHHHH!!!!!
Can't . Revit does this:
If i increase the slope above 1/12, and/or increase the thickness of the roof to 1" or more, it works fine.
Then increase the thickness to 1". You are not going to have a bare layer of 5/8" plywood as the roof, are you?
There shouldn't have to be another work-around for yet another Revit tool that doesn't work properly. I've encountered this problem before, for example when modeling a curved roof by profile, where the high point of the curved roof is nearly flat. Given the nature of Revit building components vs how buildings are constructed IRL, I model 2 or 3 roofs for a whole assembly. Sometimes there is part of of the assembly that is that thin.
Neither example is a square cut, and you're roof slopes are greater than 1/12
That's exactly what doesn't work for me. I cannot set the fascia depth to 5/8", only up to 9/16", and it gives the horizontal cut. Anything greater than that, and Revit will throw an error and want to delete the roof.
