Welcome to the Revit Ideas Board! Before posting, please read the helpful tips here. Thank you for your Ideas!

Fascia and Roof

Fascias are located under the roof sheathing and set back from the bottom edge. The typical slopped residential roof is 5/8" thick sheathing covered with shingles about 3/8" thick making the roof about 1" thick. Below the roof is the roof structure. When I model I make the roof 1" thick because it is. 
Due to multiple roof pitches, the inflection point is where the fascia and roof meet. 
The dimension we use to locate the roof is the heel height. It is normally measured vertically on the same plane as the face of the studs from where the roof truss meets the studs to the underside of the roof sheathing. It is so much easier to do this in AutoCAD.
Please make the fascia tool able to locate the fascia in the correct place.
Please make the fascia tool able to locate the fascia based on the bottom of the roof instead of a variable location.  See attached images. The second image is not a truss.ROOF EDGE 1.jpgROOF EDGE 2.jpg

You can do this in Revit already, you can select whatever edge you want as your host for the fascia, same goes with gutters. If you have the 1" thick roof and structure modeled separately then you can just select the bottom edge of your roof sheathing as the host reference for the fascia.
