I copied the K-series bar joist family that our engineer was using in Revit Structure on one of our projects, and modified it to allow separate instance joist extensions at each end of the joist. To make the joist slope, you can either use a sloping reference plane, or just change the Work Plane to Pick a Plane and choose the bottom of the roof when you're placing them. This is a 2-pick family, just like wide-flange beams, etc.
