Walls not intersecting

[onestoreyllc]

These walls all intersected properly and I changed the strength of the drywall and this happened.  I returned the drywall strength back to it's previous number but the walls still don't intersect. 

help?

I think it’s a saved view in the view map? if yes go back to the source view in project map and you will find it well intersected then from navigator go to view map again and right click on that saved view and choose redefine view based on current settings, it may be fixed.

Unfortunately this is happening in the source view

Try to change reference line location to be at core center it may help,

changing reference line location via Edit menu then Edit wall reference line location.

Can it be that the "clean wall & beam intersections" is turned off under the "On-screen view options" menu?
