Sudden change : Walls not joining properly

[Anton LH]

Hello everyone,

I know it's a pretty common subject but I can't seem to find the reason of this sudden change in my file.

I was changing my complex profile walls and I suddenly realised all the wall connections in my file don't join anymore, not only the complex profiles. The "clean wall intersection" is turned on on the view panel. walls are on the same layers, with same properties (junction orders etc). 

When opening another file everything seems fine. But when I copying and pasting the complex profile wall it doesnt join properly anymore as well (only the complex profile wall that time, other simple walls are joining properly).

I'm clueless with this one. Is there another option that I have turned on or off without realizing ? 

Thank you for your help !

Check the current Layer Combination. Any chance that the Layer Intersection Group of the Walls' layer is set to zero in that Layer Combination? If the Layer Intersection Group is 0, no intersection occurs.

Thank you Laszlo ! It effectively worked, didn't know that if the group is 0 no intersection can be done. 

Thanks again
