Wall join Guru needed

[Andre Baros]

Why oh why does Revit choose to make the same wall join 2 different ways for 2 different conditions and for each say that there is no other option available.

See attached. On the left end of the low wall the walls clean up correctly, on the right the outside wall is notched to meet the courtyard wall. If you pull apart all the walls and then pull them back together both corners always end up the same way. If you use the wall-join tool is says that there is no other option available. What recourse do we have.

The walls by the way are pre-cast panels using a ruled curtain grid to create the module and regular walls as the panels. More time has been spent trying to fix this corner than to draw all the walls on the project (not that that took long)

How about pulling the low wall away, right-clicking the end, and disabling the join? I've been disabling joins a lot for a long time :-)

[Andre Baros]

When you have a wall in a curtain wall, which wall do you disable joins for? BTW, when you disjoin the low wall, both corners look wrong, go figure.

Wes, I was hoping you would answer, I was afraid your answer wouldn't work... aargh.

[Andre Baros]

Ok, I figured it out. One of the couryard wall was was drawn "toward" the exterior wall and one was drawn "away" from the exterior wall. When the "start" points of both walls was on the outside both behaved the same way.

Question, is there a way to identify or change the "start" and "end" points of a wall (or line).

Thanks again.

When you click on a wall, the double control arrows indicate the exterior side of the wall. I've never been aware of a start and end point to a wall... except that by default, going clockwise around a building orients the walls properly... all I've known is the outside face and inside face of a wall.

Revit does not note the start and stop, but through the positioning of the "drag wall end" blue square, you can tell whether the wall was drawn at centerline or edges.

[Andre Baros]

I don't understand. Changing the "drag wall end" condition did not make the wall's join correctly, we tried every permutation of the ends intersecting and butting (manually pulling them apart and pushing them together) with no results. Deleting the wall and drawing it in a different direction solved the problem instantly (and since these are curtain walls, there is no center or edge control). I don't know of any official recognition of start and stop points, but the behavior indicates that it it relevant.
