My Plumbing-Pipes have a slope of 2%. Now how do I add a Vertical Dimension the Pipe and the Ground Floor?? The construcktion workers need to know in which hight above the ground the pipe needs to be installed... But sadly the Dimensions-tools only work with pipes which are parallel to the ground... So I draw a detail-line parallel to the ground at the measureing-point.... and I do this all the time. Please create an option to add a Dimension between unparallel elements.
