I'm sure you had to do a lot if work to get that macro to work properly. Mine is adequate for me even if I have to manually enter the overhang amount. I draw a polyline to get the total length even though it will not work in all cases. Thanks for your input.

OK Thanks

There are a few here: https://3dwarehouse.sketchup.com/search/models?q=lion

I tried this in a text object without success: "Projected Overhang Area: #{projected_overhang_area}"

Is the open or closed cell spray foam any cheaper in your are?

Thanks Joe. BTW what insulation type & R value are you using for roof plane?

Is there a ruby variable that would return the default roof overhang value? I'm using this in a roof ventilation calculation text object. I used 1.4' as a constant in the version. Ventilation Requirement Calculation Attic %$attic_area.round(0)% sq ft / 150 = %($attic_area/150).round(1)% sq ft. required ventilation area %$soffit_Length% lineal feet of soffit x 1.4' width vented area = %($soffit_Length*1.4).round(2)% sq ft vented soffit x 0.08153 (11.74 sq.in. vent per sq ft / 144) Soffit Vents Total %($soffit_Vent=$soffit_Length*1.4*0.08153).round(2)% sq ft Off ridge Vents 3 ea 4' = 414sq in / 144 = %$ridge_Vent = 2.9% sq ft %($ridge_Vent.to_f + $soffit_Vent.to_f ).round(2)% sq ft vent area provided (%$soffit_Vent.round(2)%+%$ridge_Vent.round(2)%)

I was able to get it by changing the base line slope & the pitch.

I did a few of these 10 years ago but forgot how I did it. The new ceiling addition on the rear is [9'] one foot higher than the existing house [8']. I want a sloped plane between the two roof sections. Any ideas?

Thanks for confirming Robert.

Main roof is cantilevered trusses with 24" overhang. One 10' section needs to be a shed roof over a pop-out. How do you mix flat soffits & sloped soffits in the same roof plane? Or do I need to create another roof plane over that section? I built the framing in that area manually.

Clever solution. I suppose you could capture that with CAD Detail from View & make cad block. Then close the wall again. That way it would not show up on Electrical & HVAC plan views. Just a thought.

Thanks JK. Most of the work involved the framing. Just wish the Match Properties tool was more versatile, more properties, & would work in elevation view. All done now.

I did that for the exterior. Moving on to the interior now. Just wish I could select based on "absolute" elevation reference.

I have a situation where a 6000 sq ft 3 story house plan is near complete and the owner wants to raise the 1st floor ceiling by 3 feet. Easy enough to add 3 feet to the ceiling height. But all items that are absolute heights do not go up. So I want to go to 2nd and 3rd floor and roof & group select these items. There seems to be no way to select by elevation reference. Any suggestions?
