Rafter Size Issue

[OrinCrowder]

Trying to use lumber rafters beyond trusses for a roof over a patio. No matter what depth I make the rafters they will only show at the same depth of the top chord of the truss. In this image the rafter is a 2X10 extending from a 2X6 truss top chord. If I extend the rafter farther into the building, alongside the truss, that portion will show as a 2X10 but beyond the truss it will only show as a 2X6. Any ideas what's going on?

Forgot to update info - now using X15.

Do you actually have a roof plane in place or are you extending the rafters beyond the roof plane.  Trim to soffit may be the reason you are getting 2x6.  Just a guess though without seeing the plan file.

You'll get the best help if you post the plan file.

Draw a roof just for the patio with its own needed framing spec.

Thanks everyone - much appreciated. Turning off trim to soffit did show the rafters as 2X10s but also added a trim cut where the rafters meet the truss top chord (image attached) - guessing that's because one roof plane can't have both truss and rafter framing method. Drawing the separate roof plane seems to be the answer.

Chief’s roof framing is not always as it would actually be done on site. 
 

Is such a 3D framing image a requirement for your permit office?
