Be Consistent – Wall Location Line:

This is going to seem an obvious, but being consistent with the management of the wall Location Line constraint is essential when laying out walls in your project. When I dig around users projects, I often find inconsistent strategies, which “can” lead to issues with wall joins. You can set the wall location line parameter when you first place a wall, this is available from options bar.

New users often don’t know what all these different parameters are or what they even do. They merrily go away & place walls with different Location Lines set, only to find that walls are not cleaning up as expected. Let me show what each of these parameters are referring when you place a wall. The diagram below shows what each parameter alignment does.

The Core boundary is set in the wall type itself. All wall system families have a core Boundary, internal & external. Observe that its the “green” lines in the screen grab above.

Now whilst this might be a slight sweeping statement, but I advice users to be as consistent as they can. If you are placing your external facade walls, typically ensure they are all set to the same location line. Also, watch the location you choose. If you choose Wall Centreline & you have to flip the direction of the wall, there are no differences, as you are mirroring the wall around its centre line, on which you placed it. If on the other hand you choose Finish Face: Exterior, when you flip the wall, you are flipping the whole wall width, this can impact areas, so be mindful of this.But if you have to change the wall makeup, then Finish Face: Interior may be preferable as you might not want to impact areas within the building.

“Ok!'” What do you recommend then? To play safe, I either make all my external walls be Finish Face: Exterior or Finish Face Interior. What I choose very much depends on the project stage & whether I know the wall build up. As for internal walls, I try very hard to always make internal partition be wall centreline. This strategy has worked for me, I hope you have similar success. But do remember you can change the wall Location Line at any time if you need to, by selecting the wall & changing the Location Line parameter from the properties dialogue box.

Dave, when auditing a project (and trying to fix inconsistent location lines), do you have any tips on the most reliable way to do this?

If a wall is oriented incorrectly and needs to be flipped, do you recommend switching to 'Wall Centreline' and then using the flip control?
