walls not joining

[Gus]

I can't for the life of me get these two exterior walls to join without a void in 3d. In plan view they unite but not in 3d. I have eyedropped the walls so they have the exact same parameters as one another. Anyone have a clue as to why this might be happening?

Have you used the Intersect command with both walls on either side of a corner selected to be sure that the reference lines do in fact join?

Is there a hidden column in the corner?

Off topic - it looks like your floor slabs are 'proud' of the face of your exterior walls. If that is intentional to get a massing for a belly band, I can understand.... but you have the edge showing wall siding, so I'm guessing not...

This makes me wonder if your exterior wall reference line is not on the outside of the wall. (or you have an offset specificed) If it were, the walls would have snapped / aligned with the slabs.

Some other possibilities:
Duplicate walls at the same location in plan
Walls not on same story...

I think You made extra little walls to make faces for Your ceiling - they maybe make the troubles..

Two walls in the same place - even when thy are different in hights can cause such trouble.

Another criticism (sorry). You said "two walls", but I see 4 walls, two on the first floor and two on the 2nd. Or you made only two but crossing the slab in the middle?
Did you try dragging the walls (or a copy of them) aside, and watch if standing alone they connect correctly?

Thanks guys,
Somehow I fixed it.
I honestly can't say how for sure.
I think it might have been the fact that I had an existing wall that was the same as the modified wall. Since I am doing an addition I have existing plans then another set of plans over that showing the modifications.
I'm having trouble figuring out a good way to have an "existing" model in the same file as the "modified" model without weird overlap things happening. I am wondering what other people do in similar situations because it's important to have exiting plans and not to mess with them. It's also good to have a demo plan which has the same "duplicate walls" effect it seems.

Ah, so Hmooslechner was correct in his guess.

Well, AC now has a renovation feature that allows elements to be tagged as existing, demo, new and to generate uniquely displayed drawings for each type of plan.

Since you are still on 14, the only method there is with multiple layers - but you need to make sure that hidden elements do not interact with visible ones. So, for your existing plan, where new elements are hidden, or your proposed plan where demo elements are hidden, those elements must have different intersection priorities in the corresponding layer combinations so that they do not interact with the visible elements. There is a lot of old discussion about ways of managing renovation / remodeling work with screenshots if you search the forum.

Besides reducing the number of layers for a renovation project by about 1/3, the new renovation feature provides custom model view options - changing fills, pens, etc - for demo elements in a demo plan, vs how they appear in an existing plan, etc. Along with Morph and many new features, worth considering an upgrade to 16, or some time time year, to 17.
