Hmm, didn't find the answer I needed, so I called Tech support. Alex was very helpful....here's the trick;
I had a situation in which I was tying in the roof over an addition to the existing roofline.
I pulled back the eave at the area in which the addition was being tied in.
The gutter at the pulled back roof edge was no longer wanted....
I selected the roof edge and looked and looked until I figured out I was not going to find the answer.....
As Gene mentioned, there was a "no molding on selected edge" option that had been available here previously.
The gutter polyline is not accessed by selecting the roof edge, but the gutter itself. Once I had selected the gutter along the roof edge in question,
I simply opened the object and voila!...my little checkbox thingy was right there waiting for me.
Hope this helps somebody.
