I am new to Revit after using Autocad, Rhino, etc for years. When I create a wall or draw boundary lines for a floor, no matter what dimension I enter, revit enters it as 1 1/2" smaller. This happens even if it is the first object drawn and there are no other object it is constrained to. If I enter 50' 3-3/4" revit will change it to 50' 2-1/4". I is happening over and over again regardless of the actual number entered. I have searched online and in forums for an explanation but I cannot figure it out.
Thanks in advance for answers!
