Issue:
How to create an arc length dimension constraint in AutoCAD.
Solution:
It is not possible to constrain the length of an arc to be a specified value using
dimension constraint.
However, it is possible to apply a combination of Angular and Radius constraints as shown in the following video.
The formula used for the Angular constraint is:
([Arc length]/[Arc radius])/(360*(2*Pi))
