This is my first time posting so I am not sure if this is in the right category. I am trying to create undefined ductwork in AutoCAD MEP 2013 with single line. Then convert it into double line using the Calculate Duct Sizes. It always converts my branches into Tee's with a 90 Degree Angle. Is there a way to have it use a wye or create a custom Tee that can use a 45 Degree Angle?
Thanks
