This post was inspired by this discussion. This issue is described in SPRs 687261 and 837334, the latter was created for me on 11/11/2014 (the other one I simply found on my own).
If I create an edge flange and dimension the length based of some other feature of the part, all is good. That's parametric modeling, right? Now, if I delete whatever feature is driving that edge flange, I see absolutely no indication that anything is wrong. The feature manager does not show any warnings, and only if I go into the sketch of the edge flange do I see the dangling dimension.
Anyone else experience this? If so, do you have an open SPR for it? If not, will you please vote on the two referenced above?
