Hello,
I am a fairly new Revit user and am running into a potential problem. I have created a two story home with a floor and ceiling plan added to the second level, I found a wall that had been readjusted for some reason and tried to use the align tool but it gave me an error saying "can't make extrusion" when I expanded out the reason errors it said for 1 and 2 the problem had to do with my ceiling and also says my ceiling sketch is invalid in error 3. I deleted the elements it gave me errors on and the wall adjusted, I cannot see any difference in the ceiling plan so I wonder if that is going to create problems later? Sorry for being such a noob.
