Attic wall changes with build roof command


Recommended Posts

Hi, I have done some manual changes to the roof. And I want to add a porch roof to the entry. When I choose to build roof and retain my manual changes, it then changes my attic wall over the garage by lowering the top of wall and changing its formation. I have attached before and after pics (PNG & PDF) and the CA file in X12. Please let me know if you have any question that may help you help me.


Thank you

Your image shows framing, not a wall. What is "formation"?


What's in the PDF? Could you post it as an image?

That's a tricky one.  I think Chief just sees that area as needing a roof plane for some odd reason.  So it builds an extra little plane which cuts your wall off.  You may have checked both Retain Manually Drawn Roof Planes and Retained Edited Automatic Roof Planes, but that is neither an edited auto roof nor a manually drawn plane.  Chief simply sees it as a missing plane.  I say just delete the extra little roof plane or draw the entry roof manually.  I would personally just do the latter.

Thank you everybody. It was the small roof plan that is circled in red that automatically continued pass that front wall. I was going to cute/paste after I re-build the roof but i was just able to delete the extra roof and that solved the problem.

Rectordesign7... lovely garage roof, but just a heads-up in case you're not aware, the shingles at the top of your curved roof will not meet the min. slope requirement for shingles (2:12 min).  You'll need to address that with some non-shingled sheet material at the top in a call-out or a detail.

Thank you for the comment. Interesting, I didn't think about that for a curved roof. Personally I don't like them. But I am going through one of CA online training tutorials to learn the program. I am seeing what areas I need to work on and what new things I can learn.

      I'm having an issue with how the roof layers populate in Chief Architect.
      I want the roof "surface layers" to all be above the "fascia top height".
      Right now it always starts the roof "Surface Layers" 7/16" below the "Roof Plane Line".
      When building we align the outside corner of the face-board with the top plane of the "roof structure", Trusses or Rafters which should be the roof plane line.
      The OSB, Underlayment, and Shingles rest on top & outside of the face-board / "fascia top height" that is aligned with the top of the roof structure.
      Chief Architect consistently lowers the roof structure 7/16" (in plane with the roof surface) from the "Fascia Top Height" no mater the pitch.
      In order to get things to work I have to add a 7/16" layer to the "Roof Surface" and Subtract 7/16" from the "Roof Structure" (e.g. rafters) in order for the cross section to show the layers correctly.
      This works for any pitch meaning that the roof is dropped 7/16" (in plane) with the roof surface.
      The reason this is important is because I need to show Fascia Top Height in Elevation Dimensions and if I have to shrink the framing members, they are not modeled / sized correctly.
      I'd like to know if there's any way to adjust this default "Fulcrum" without the hackey way I'm doing it.
      I want to be able to specify the fascia top height and have roof planes properly populate from that point.
      It's important to note that in this image both "Fascia Top Heights" are the same with the only difference between the two being the one on the left is a 7/12 and the one on the right is a 4/12.
      Where the green lines intersect represents the "Fulcrum" that the roof revolves around at the outside of the face-board by default and the red line shows the default top of the "Roof Structure".
      I have to add a 7/16" layer between these planes in-order to get the OSB to be above the green roof plane line & top of face-board.
      The roof "Structure" is always 7/16" in plane below the "Fascia Top Height" / "where the green lines intersect" by default from what I've been able to figure out.

      I'd like to know if I am missing some setting that could change the "Fulcrum" point in relation to the roof layers.
      I've spent allot of time figuring this out but have not found a setting to fix this yet.

      Made a video to describe what I'm wondering...
      I hope the behavior of building the roof using "auto rebuild" is normal Chief behavior - because I have to admit I've never noticed this before today.

      Hello, I am looking for some advise on how to improve the intersecting roofs which will overlap gable roof onto the hip roof so water avoid the corner on an addition project for myself. In the "elevation" picture, the hip roof to left is existing roof that will be extended to insect the new addition gable roof to the right.  We like floor plan layout and ceiling heights but having trouble getting the roof line correct. I have attached the plan file and some snapshots.
      Second question: How would I create the roofline extension like the attached "roof line" photo?   
      Thanks for help.

      Hello there!
      I'm new to chief as of a few weeks ago. I'm really loving how in-depth you can get with it. Hopefully this isn't to much of a newbie question that is easily answered somewhere else but I have seen anything on it. I'm trying to attach a shed roof to a gable. I have a feeling this is something similar to a porch roof, but after messing with it for a few hours I cant figure it out. 
      This is what I'm go
      Here is where I'm at. 
      I've attached my plan if that helps!
      I'm using x12

      I am having some problems with getting the garage roof to be an 11/12 pitch and the attached house being 8/12 pitch, one of the roof planes is part of the garage and apart of the house. I am new to this and can't draw the roof manually very well. I have been using the auto roof and just changing the settings. 
      Thank you!May- Lot 73.plan
