Lighthouse Posted July 9, 2019 Share Posted July 9, 2019 I asked this years ago, but maybe there is now a way to do it. I've designed a roof with overhangs at the gable and rake. I want to create a tapered roof edge (angled soffit) so the roof gets thinner towards the outer edge of the overhang. I can create this tapered edge with a PS, or rafter tails, or a molding polyline, or a shadowboard on the gable end (soffit A in the attached drawing). But nothing seems to work on the rake edge (soffit B in the attached drawing). I would greatly appreciate any brilliant ideas. I have attached a simple test plan as well. Thanks!! soffit test.pdf soffit test.plan Link to comment Share on other sites More sharing options...
javatom Posted July 9, 2019 Share Posted July 9, 2019 Try using another roof plane for the soffit. Make it thin so it does not cut into the actual roof. The soffit would be the ceiling of the roof plane. Link to comment Share on other sites More sharing options...

I'll give it a try, thanks Link to comment Share on other sites More sharing options...

On soffit B, I want the slope to be perpendicular to the wall plan (starts low on the wall, ends high at the fascia (easier to see in the pdf). How do I make a roof plane that slopes in two directions- it has to slope to follow the roof, but also slope up towards the soffit Link to comment Share on other sites More sharing options...

How do I make a roof plane that slopes in two directions- it has to slope to follow the roof, but also slope up towards the soffit as I mentioned, you will need to adjust the baseline angle to match the slope of your roof which is 15 degrees. then set your slope of the "soffit" roof plane to the degree you want, like -12 etc. Link to comment Share on other sites More sharing options...

Can you do it on the attached plan and send it? I'm happy to pay for your time. I just want it to look like the picture. Once I see it on the plan I will understand what you did. Actually, unless you have X10 I won't be able to view it. Just to make sure we're on the same page, you are talking about Soffit B, right? Do I draw that roof parallel to the existing roof or perpendicular? Link to comment Share on other sites More sharing options...

I didn't realize that baseline angle is in the "z" direction, I thought it was "x" or "y". Link to comment Share on other sites More sharing options...
