ceiling joists won't mitre to roof plane

[winterdd]

Hey Guys, I am designing a simple carport for a client. On this project they already have an existing slab, I am not sure what it once was, maybe a parking pad. The builder wants to to bury the posts on the outside of the slab and let me tell you right now CA doesn't like that. It is messing up my roof and ceiling joists. The LVL's are on the outer edge of the posts which makes the roof "baselines" messed up or something. I need to mitre my joists manually or something. Any suggestions, see below? I wish I could figure out how to ask this in a more understanding way but I can't.

 

My existing slab is built with railing walls by the way. Maybe try and erase those walls and build a simple "slab" with the slab toolbar?

That's what I would try Rob..  I'm not sure if that is why your ceiling joist are wacked, but if I don't need a room definition, then I usually do a slab then do the roof on top.  I model my own post and beams anyways, so it isn't to much of a bother.  Railing walls are some time finicky..

Yeah, the ceiling joists still aren't wanting to mitre even with a manual slab drawn with now definition. I gotta outsmart this I guess just to get the drawing done.

Howdy Rob,

 

It looks like your roof planes are too low. Maybe the roof planes were built before your LVLs placed. Post your plan.

 

Best,

that's strange. i just drew a railing around the perimeter and deleted the floor in the room definition. then made a polyline into a slab to fit inside. no problems.
