Problem with wall corner joins

[adaf997367]

Hey there,
I have a serious and very time consuming problem with joining the corners of my perpenticular wall joins. If you take a look at the attached photos you'll see the problem. However some corners join neatly as shown in the 5th attachment.
Do you have any suggestions?

I hope one of you guys can help me out - it will be appriciated a lot!

Are you sure all your wall ends are set to allow joins? If so you could try pulling them apart and using the trim/extend to corner tool. Or you can click on the blue grips for each wall and they'll usually cycle through various wall join conditions.

Change your core boundary material to something like Wood Studs....its probably getting confused with all the Thermal/Air layers...

And check to see if your walls are the same height (base and top elevations), which can sometimes lead to clean-up weirdness.

Also check for any walls above or below those views (out of the view range) that may be intersecting that same location. That can cause issues, as well.

Thanks a lot for all the suggestions.
I tried them all with no luck. I did however find out that having room separation lines (on the exterior face of the exterior walls) and room bounding properties creates some inconsistensies. I had to use the seperation lines to get the area all the way to the outer face and somehow when splitting the walls that spand between the ground floor and top of the roof, gave the upper walls a tick in being room bounding even though the original walls were not.
Thanks again.
