When designing parametric models, often I need to reference a dimension which is fully defined by other parameters while calculating a new parameter. For instance, I might have a angle for a riser coming out of some footer, and I need to know it's complement; or I have a pair of lengths and an angle, and I want to reference the third leg of the triangle that creates in one of my sketches. In Solidworks, I can name this dimension and reference it elsewhere, it would be nice to have this functionality in Fusion.
