I am working on detail component families for different bend conditions. It is basically a series of families for hooks so we can match Revit's *ahem* awesome looking white filled 3d rebar. The hook lengths are all dependent on the bar diameter and I had no problem getting the 90 and 180 degree bends to work the way i wanted but I am having a difficult time getting my 135 degree hooks to work right. I have been drawing everything at #4 bar because the 1/2" diameter is easy to work with and then I'll just make new types when I get everything working right, but on my 135 degree bends whenever i switch views to a different type I keep getting error messages saying my constraints are invalid or it cant draw my filled region. I suspect it has something to do with dimensions going to an arc and I wanted to see if anyone else has run into this. I can't post a screen shot until Monday but was hoping someone might be able to answer this off the top of their head. If I don't get any response I will put up a few images of the various reference plane and dimension locations i have tried so far.
