Railing wall to exterior wall

[builtright3]

I'm having issues with railing walls and the way they effect other walls that they connect to. Does anyone understand these behaviors? In this case I want the post to be next to the existing wall but I want to connect or snap to it. I have to move them apart to make the siding come out right with color.

The different colors is because one is the default wall siding blue color and the others you have painted white.

 

Either paint the blue one white or change the default wall siding color to white.

You can select this part to change the wall color

If I move the post (railing wall) away from the wall it clears up

Think of it as an extrapolation error.  Chief doesn't see the intersection correctly and extends a wall material to hide it using the default siding color.  If the house was default blue you wouldn't know chief had cleaned it up.  Similar to some of the crazy attic walls shapes Chief sometimes draws.

Changed the default and it worked great. Thank You Sir!
