I am doing a a school project using Revit 2020 and I am having issues with dimensions when it comes to aligning straight walls with curved geometry. I am using the "Basic Wall Exterior - Wood Shingle on Wood Wall" aligned using core face exterior. I am trying to add a circle centered on one of the corners of the building, however I do not know how to do this without breaking the dimensions. When drawing a circle to a 6' radius using these settings, the radial dimensioning tool set to Faces of Core ends up dimensioning the circle to 6' - 0 5/8". I am unable to edit the radial dimension to change the actual radius of the circle also. Is there an easy fix for this?
