So I'm designing a building and I'm using the conceptual mass option. I'm now trying to draw an arc in for the top of my building that is not possible to draw 2d. The arc I am attempting to draw begins on the z axis forward, then climbs up and to the right while also finishing deeper on the z axis. It is kind of like the shape of a "Y" in that the it orginates at the intersection of said "Y" but forward. Then the arc moves away and up to finish at the top of the right arm of said "Y" all the while the arc needs to lean back.   Any help on this challenging line would be greatly appreciated! I have included some screen shots of what I'm working on.  I think if I could somehow rotate my reference line from the end. 45 deg.  then I could draw my arc at the correct angle but the rotate tool only wants to locate on one of the reference line planes...

Just a simple sketch. I have attached it. It's Just a general Idea that is still developing.. In the front view the arms of the "Y" are concave all the way up so the arcs lean back.
