ISO 128 / ISO 129 / BS 8888. Arch dimensioning.
I’m trying to bring our designs in the office towards ISO standards. This is another request for help from the community. (Yes, I know I’m getting extreme into details. Just want to do things right. 😊 )
In ISO 129 the dimensioning of Arcs is defined as in the left of the image with the orientation like the RED extension lines and arrows. SE can do the one on the right by default.
Does anyone know how to make the extension lines of the dimension perpendicular to the arc's chord and not perpendicular to the arch?
