GeneDavis Posted Wednesday at 01:38 PM Share Posted Wednesday at 01:38 PM (edited) I've a complex roof due to a cathedral ceiling below that is making for an overframe config. See pic here. You can see the 4:12 rafters of the overframed part. They are specified as 2x10s, the roof plan strucure is set to that, but the rafters are 2x6 in 3D. Select any one of them and open for spec and you see that it is a 2x10, example here. Section views are worthless, in that they are displaying the rafters as 2x6. What is going on here? Is this the bug that occurs in overframing, in which the rafters somehow default to the soffit size tails? What is the workaround? Over on the other side of the 4:12 overlay roof that is coming onto the house from the attached barn, there is a segment that is over the cathedral roof below framed by the 2x12 rafters of the 10:12 pitch of the main house gable. The section is seen in this view, and I highlighted the perimeter. This is done in 2x8 rafters and they are represented properly in 3D and section views (which are 3D). The difference between this plane and the one with the bust is that there is no bearing wall and overhang with soffit to this one.

robdyck Posted Wednesday at 06:51 PM Share Posted Wednesday at 06:51 PM The roof structure over that area has a structure depth of 3.5". Change that to 9.25 and uncheck soffits. Then, select all the rafters and open-close the dialog box. Link to comment Share on other sites More sharing options...
GeneDavis Posted Wednesday at 08:41 PM Author Share Posted Wednesday at 08:41 PM Thanks @robdyckMy file (did I not sent the right one?) has that roof plane specified as structure depth 9.25. When I uncheck soffits (and why would this work checking a box in the roof layers sub-panel?) I am able to generate a 3D proper view of a 2x10, but now I have uncut rafter tails? Why can't I have both proper depth display and cut tails to match up to my 2x6 subfascia? Link to comment Share on other sites More sharing options...

My mistake. I has accidentally selected the roof plane over the garage. Link to comment Share on other sites More sharing options...
ChristianA Posted Friday at 04:26 PM Share Posted Friday at 04:26 PM I think I may have figured out why your overlay roof is not framing at 2x10. There is no gable wall that goes to the underside of roof to define the break between soffit and attic cavity. I checked "roof cuts wall at bottom" for your attic wall between the trusses and overlays and it brought it up to the roof plane, which fixes the framing. I would imagine another way to fix it is to change your gable sub-fascia to 2x10. Link to comment Share on other sites More sharing options...
