Ceiling joist through roof plane

Recommended Posts

Does anyone have any idea why this is happening?

 

The roof plane cuts through the ceiling plane so that near the exterior wall the ceiling is the bottoms of the roof rafters.

It could be a previous auto frame and then you changed some walls, ceilings etc.  Try rebuilding the ceiling framing.

Was just thinking the same thing.....

Check your room definitions.  You have a layer of drywall within the structure tab AND  a finished layer of drywall.  The doubling up of ceilings is confusing the framing.  Delete the one under the structure tab and rebuild the framing and you will be fine.

Doug,  You also have a bunch of rooms set to "Use Soffit Surface For Ceiling" which is seriously weakening your rafter spans.

Thank you gentlemen. Both of the observations and suggestions were very helpful and have solved the problem.

      The red arrows point to the problem area.
      The outside wall and interior wall at the closet intersect with the valley where the two roof planes intersect.
      The interior of the room creates an attic wall (with exterior siding) above the closet (NOTE: Ceiling was removed to get image)
      The plan view shows where the roof planes intersect at the valley. I have the same problem on the other side of the house because it is symmetrical.
      The plan is too large (65MB) but here is the model (https://3d-viewer.chiefarchitect.com/go?share=543146417714334).
       
      Any suggestion on how to fix this would be greatly appreciated.

      Civil engineer asked for roof plan. Currently. I have been able to display roof plains by floor level with slope markers. However, being it is a two level home...how do I display a complete roof for a layout plan? Along with dimensions for roof rain displacement calculation?

      Hey all,
       
      Sorry for the slight tongue-twister of a title. I'm here with another novice question.
       
      When creating roof plans to send to layout, I'm running into an issue. After I choose to display all of my roof planes on the same level, they appear as though the program is deliberately displaying the lower roof planes on top of those that should be above. I've attached a couple snips showing an example of how one of my roof plans is drafted and another two with what that plan looks like in plan view. It's in the roof plan view but it looks the same regardless of the layer set I use.
