I have a question or wish to organize dimensions according to active Cplanes (or current view).
For example, when detailing a building there are many sections and layouts, dimensions overlapping each other from floor to floor. That would be great if dimensions include a property that specify a NamedCplane or NamedView and it would be visible only in the specified viewport only. There would be a command that reveal all dimensions as well in terms of missing element if user fail.
That could be enhanced with lines and hatches for construction junctions during detailing them.
