The Wall cross-section does not trim to match the roof slab angle?

Anonymous
Not applicable

I have extended the walls to match the roof line of the roof slab using the 'auto project' function. However the walls parallel to the ridge protrude through the roof as the walls have not been trimmed across their respective cross-sections. How can the walls be trimmed to match the roof angle?

Auto-projected Walls that run parallel to a Roof slope will be extended upward until the Justification line intersects the bottom of the Roof object.  The top of the Wall will not be sloped. 

 

Your image appears to show a very thick Wall with the Justification line at or near the interior face of the Wall, with a significant amount of Wall above the Roof.  One way to get the top of the Wall sloped would be to apply a subtractive Interference.  If the combination of Wall thickness, Wall Justification Line location, Roof thickness and Roof slope keeps the Wall above the underside of the Roof completely within the Roof, you could use the Roof as the Interference object.  In your case, you would need to create one or more objects (Mass Elements, perhaps) with a bottom plane at the underside of the Roof and sufficiently thick to fully engulf the parts of the Walls that project above the bottom of the Roof, and use that(those) as the Interference object(s).  Put those on a unique layer and freeze it.
