Wall layer lines GONE!

Attached jpg says it all. My cavity wall is looking a bit dodgy!

Has someone maybe used the "invisible line" tool on this? You can try using the "by category" line to rule that out.

You may also want to check in VP that "clean up all wall joins" isn't selected.

look at the wall level constraints.

if the walls goes from level _ to level _, the change the upper constraint to 'unconstrained' with the proper height.

if the wall goes from level _ to unconstrained, choose a level for the top constraint and if necessary enter an offset.

this will most likely fix that graphical error.

i believe it is a glitch.

We saw this problem pop up in 2010. When you have a niche (void) that doesn't cut through the whole wall some of your wall layers (common edges) will disappear.
Moving the offending layers into the core itself solves the problem, but screws up your intersections.

OK, that's a bit annoying. Common edges was unticked in VG overides on the view template. Not a setting I ever change so who knows.

Funny thing is, I had a similar issue in the same project where a wall wasn't appearing correctly. If I switched on Reveal Hidden Elements, selected the wall (nothing more) and switched back, the wall would appear normally for a period.
