I noticed that currenly it is not possible to use a referenced dimention for defining other parameters. Let's say that I would like to adjust the diameter of an inner-circle to e.g.1/3 of the diameter of an outer-circle that is fully constraint with tangent inside some geometry. In this senario the outer circle can only have a reference dimention added but it can change in size if the rest of the geometry that is tangent to it, is modified. Right now I have to implement a complex function to find a relationship with other parts of the geometry so that it will correspond to the desired 1/3 (in this case) that i am trying to implement.
It would be simpler if I could use the reference parameter to directly calculate the desired 1/3.
