Question on custom Eves and Exterior Trim

[Camatt]

Hi! 

 

I am trying to draw as-builts for my home. Below is wall section I made using a simple draw program.

I am looking for assist on the following assist:   (I use CA-x14)

 

1) How do I build the roof overhang to have these partially boxed eves?

2) On the bottom of my stucco walls there is 2" foam with a 45 degree cut corner. a) I tried to make a pony wall section with the correct layers. This worked, but it lacks the 45 degree cut. b) I made a poly-line moulding, but I cannot figure out where to add exterior trim to walls.  Any ideas on the best way to do this?

1.  I'm not sure you can build the exterior soffit automatically but you might be able to get close with a molding polyline.

2.  You can use a molding polyline for this skirt molding.  For both, draw it in elevation as you have.  Convert each to a separate molding so you have better control for each.  Next, go to plan and right click just outside of the exterior walls.  You'll see the building outline as selected.  On the popup edit toolbar, choose make molding.  Assign your molding and set the height to where you need it.  You can add both molding to the same line or use separate ones.  It'll be more difficult if you heights vary per building section, but this should get you headed in the right direction.

HERE'S AN AUTOMATIC ROOF METHOD.

• Use an invisible exterior wall to define the 38" exterior space, like you would for a porch (if you want concrete floor below it) or open below (if you want terrain below it.)  Use same exterior wall to ensure same exterior material thicknesses, then make them invisible.
• Specify the exterior room to be either "porch" (if you want concrete below) or "open below" if you want terrain.
• Specify the exterior room to have your net 18" overhang  (56-38) - Actually it should be 16 13/16"  (56" - 39 3/8") based on your drawing dimensions, but this is just a demonstration.
• Make the room's rough ceiling to be 13.5" below your interior room ceilings.  (107.5" - 94") based on your drawing dimensions shown and assuming same thickness of material.) 
• I don't know about the rest of your structure, but on my model, I specified all trusses with roof automatically drawn and 6-1/4" heel height initially.  Chief raised the open below areas to 8-9/16" automatically and left the rest of my model at 6-1/4" heel height.
• Elevation camera with framing layer set turned on doesn't show the lower soffit finish material.
• 
• However elevation camera with section view layer set turned on and within that layer set turn on framing for roof & walls and it now shows. 
• I found best was backclipped cross section camera, which isolates the truss without showing gable end of my model, with same section view layer set w/ framing for roof/walls turned on, I'm getting a extra 1/8" on the overhang, but everything else matches your drawings.
• 
• Note:  Chief adjusted heel height here to 8 9/16" above top plates.  I forgot to dimension this.

UNFORTUNATELY, manually modifying the trusses was a problem I couldn't readily solve. 

1. Again, with heel height = 8 9/16.
2. No invisible wall outside the building.  Just 56" overhang.
3. Break the truss outside the room and drop 13.5" to match above.
4. Unfortunately the under soffit and exterior materials continue to extend to the top wall plates intersection point.
5. Even creating a zero pitch flat ceiling plane at the correct soffit height doesn't change #4

.  

 

I use the automatic method most all the time.  I've tried this using soffits but can't seem to get the framing automatically right. 

Here's the plan view of the automatic method.  Remember overhang is specified from the Invisible Open Below walls.

 

 

I hope this helps.  Let me know if you have any questions or concerns.
