Salt box or Gull wing roof

Recommended Posts

I have a very simple small house design, but even after watching all the roof training videos I'm still not sure how to handle this.

 

I've included the file.

 

The cabin is 16 x 34 with an 8' porch with roof. The upper pitch is 6/12, but I can't get the lower roof to change pitch to 3/12.

 

I tried to control it at the porch "wall" and then the house wall. neither worked.

 

I also have something weird going on with the porch beams.

 

I want the pitch to flatten out over the porch obviously.

 

Thanks!

Make it two different roof plans and set the pitch manually.

Dudley, I've repaired the plan (I believe) maybe before the guru's got to it. Any way, I copied the facia height of the house, used that for the ridge height of the porch roof, then copied pasted into the roof dba.  Added the end roof by manual roof tool, used the facia height and top of ridge for it as well.  Also, your deck rail and beams weren't generating correctly because you had our steps pulled up to far. Once I backed them off rails and post generator properly.

I attempted to attach the CA X8 plan but for some reason it won't attach.  I've zipped it up and attached.  After I upload the response I will attempt it again.

Well, thank you everyone.

 

Before posting this I had created two roof planes and matched them. It wasn't too bad, but I said to myself, If CA can do mansards and Gull wings, by golly, I want to learn how to do it using the tools for double pitches.

 

For educational purposes I'd still like to attempt to use a single roof plane.

 

I am very appreciative of the help.

 

Any roof gurus out there who want to give it a shot?

Open your deck railing dbx and go to the Roof panel.

Pitch Options...check Upper Pitch and enter the parameters.

Make sure the other roof settings are correct in the other external wall dbx's.

Auto build the roofs

One question. The two side walls are part house wall and part deck. Do you set all to gable ends?

Meaning open 4 walls for gables and one wall at the edge of the deck?

Making progress. I got the roof to break and at the right place, but the fascia height became higher at the porch and thereby made the center of the roof over the house go off center.

..... 

In Railing Specification, Roof, Pitch Options, check the
"In From Baseline" number, and adjust that to keep upper
roof plane from going either up or down.
I believe the number should be the same as the depth of
the porch.

Roof still not right. The ridge needs to be in the center of the house. Can't find way to force fascias to be same height and still get porch roof at different slope.

 

This has got to be something simple I'm overlooking. It seems auto generating the roof should work if all the settings are right.

 

THX!

The best way forward is to do both the roof planes, just like you did in the first picture. So they are centered on the house and windows. Then simply move back the front door side of the roof, and add a new roof over porch. Change its pitch to say 2 and then connect it to the house roof. As my awesome wife would say, "Va Va Va Voom Baby..!"

Dudley, I've attached my attempt at helping.  IF you would please check the attachment to see if this is more like what you're after.  Also as I was working on the plan, I noted on the end deck at what would be the plan north end there is an attic wall (I didn't build it) and I couldn't get rid of it.  I opened the rail / wall dbx and checked on the attic level and it shows up as an attic wall if though there is no gable wall etc., checked there, and I unchecked the attic wall def but it won't go away. Maybe I'm the only one that had it show up?

I looked at your plan Bob and your porch roof is not 3/12 pitch nor does not auto build roofs. OP wanted 3/12

      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.

      A lot of my work involves trussed roofs.  After building the trusses, I frame the roof for the facia and varge rafters.  Problem with this is that CA adds ridge boards that don't exist in trussed roofs.  There doesn't seem to be a way to frame without ridge boards or to set the ridge board dimensions at 0.  If there is a work around, I'd love to hear it.
       
      Also....  Is there a way to frame a roof where one roof California or over frames over another roof.  In my previous CAD, I could trim the bottom of one roof to the top of another and the framing acted accordingly.  This program even added a valley plate on top of the lower roof and below the rafters of the upper roof.  That may be too much to ask for, but one can only  hope.
       
      Love to hear what y'all have to say.
       
      Thanks in advance.
