wjmdes Posted February 25, 2018 Share Posted February 25, 2018 I am trying to figure out how to automatically set the roof plane so it bears on a 2X on the floor joists when I draw it rather than keep changing the roof plane height until I get lucky. The roof plane above actually should be moved up some more and I manually added the 2X, however I know in the past if I fiddle with it long enough, CA will place that 2x when I do wall framing.

Kbird1 Posted February 25, 2018 Share Posted February 25, 2018 Did you try the Ignore 2nd floor setting in the Build Roof DBX? ( or 3rd floor etc depending which floor you need ? ) https://www.chiefarchitect.com/support/article/KB-00653/building-a-cape-cod-roof-that-bears-on-the-1st-floor-walls.html Link to comment Share on other sites More sharing options...
wjmdes Posted February 25, 2018 Author Share Posted February 25, 2018 Yes, that puts the rafters on the double top plate of the second floor and correctly ignores the third floor. I tried setting the baseline height at top of subfloor, but I apparently made a wrong assumption as to what and where the base line is located. To the manual I go.

Well, I assumed it was at the bearing point.....I just read the manual and am corrected. Anyway, I draw most of my roofs manually out of habit. What I did was measure the distance from where it was to where I wanted it and manually raised it, wallah! Link to comment Share on other sites More sharing options...

Sorry should of mentioned to put the Floor Depth (joist + ply) plus the 2x Plate height ( 1 1/2") into the Raise Setting in the Roof Build DBX, in your Case , still need to add the 2x Plate Manually I think ? as Chief has a Default of 3" above Floor before it builds plates automatically.

chief58 Posted February 27, 2018 Share Posted February 27, 2018 You can make the ceiling height of the second floor to 1 1/2" do your roofs once the roof is on change your ceiling height back to what you want it to be and you should see the plate once framed 1 Link to comment Share on other sites More sharing options...
