3 Unique Wall Intersection

Anonymous
Not applicable
I have an intersection of 3 walls and at point 4, I really want the purple to connect. It has higher priority, but it still won't work. Any pointers what I can read up on to tackle such a wall. I have quite a few such walls.

I also want the green to connect.

You just need to play with both priorities and wall reference lines. Here it is in action (the dashed lines are the wall reference lines):

Can you also do it like this?

I don't want to have 2 walls next to each other (parallel) , if it's really supposed to be 1 wall

Where are your reference lines?

So the reference line of wall 3 does not intersect with the reference lines of either of the other walls?

Auto-intersections will not occur unless the reference lines intersect, so you will have to change your reference lines to a option that allows for this. Once this is achieved, the skins of your wall should connect/clip each other based on their building material priority. The easiest way would be to change the reference line for wall 1 and wall 3 to the top surface. Depending on your composites, you could also reference to one of the bottom reference lines of wall 3 and one the of the top reference lines of wall 1.

You said: "The easiest way would be to change the reference line for wall 1 and wall 3 to the top surface". I did that to wall 1 and 3 and this happened.

Or this, which has identical outer layer

I do not get why your internal materials are not joining up now unless you inadvertently inversed the Intersection Priorities...
Material 6 has a lower IS then Material 5. You can just duplicate the material and adjust the new material to have an IS that is just lower than that of the original. Material 3 also needs to have a higher IS than Material 6 otherwise you will get a wedge from Wall 3 protruding into the wall intersection.

If Material 5 and Material 6 on the top edge of the wall are different materials, I'm not sure how you would join them without getting a chamfered corner from Wall 3...

So the BMs would be:
5 > 3 > 6
