Wall joins creating gaps, and roof to wall join issues (with material joins)

[Ksenia.Eic]

I have been going in circles with this problem and can't find anything that addresses it properly. I am simply trying to extend a wall up to a roof with the cladding extending past the "fascia" (or outside face) of the roof. In other words, I want the cladding of the wall to extend up to the flashing of the roof. 

First problem is joining the wall with the roof to get the materials to extend correctly

To do this I aligned the outline of the roof with the interior side of the furring (in the wall assembly), and then I first attached the top of the wall to the roof... and then extended the top of wall to  reference plane that aligns with the top of the roof (which makes the cladding extend up to this). In some places the cladding wasn't extending properly or was doing some weird gaps at the top left and right corners of the wall so I split it into parts and extended/fixed the cladding... The issue is one part of the roof is gabled so there are two reference planes that are sloped in opposite directions and you can, apparently, only extend a wall up to one reference line, not two... And then when I try to adjust the outline of the wall (edit profile) and extend to join with the other wall, it gives me an error "Cannot extend layer(s) of the highlighted vertically compound wall." Same thing happens when I try to draw a wall without editing the profile and extend top to the roof while also joining with the other wall... See attached

Second issue is wall joins and gaps in cladding/materials

After messing around with the wall and roof a bunch of times i've gotten it to be mostly what I want but then there are these gaps that form but I can't seem to break the wall into parts and fix it... UGH! Is there a way to resolve this as this happens ALL THE TIME

Last issue is how walls and roofs join - in terms of structure and other materials meeting properly

No matter what i do I can't get the walls and roofs to join correctly. The only way around this is to split the walls and roofs into structure and rest of envelope assembly.... this is problematic for a gabled roof, though, as doing this makes the parts of the roof not align (the slopes are the same but the ridge is offset). The structure of the roof keeps extending through the insulation of the wall no matter how I adjust the assemblies (what goes in the core). Either the structure of the roof penetrates the insulation of the wall or vice versa. See attached

1st issue:

- split the wall into 2 walls at the peak so that you can attach each to a ref plane

- or, create two roofs, one below extends to the inside face of furring, one above extends to the outside face of furring. attach the wall to these two roofs.

Splitting the wall could work, thanks. It's been problematic splitting the roof into two assemblies as it's an asymmetric gabled roof so I end up with gaps between assemblies (see attached).
