Walls on hidden layers interfering with walls on visible lay

[Anonymous]

I have been frustrated with this (glitch?/bug?/user problem?!) for some time now.

Sometimes walls on hidden layers will intersect/interfere with walls on visible layers (in 2D). The wall's fill will break at the point they intersect! If I move the culprit wall and then hide it's layer again, The break in the visible wall's fill will move too (and correspond exactly with the break) -thus proving it IS the (damn) hidden wall causing the problem.


What's going on?
thx!

It is a problem of priority of layer.

Thanks, that works... I should have searched the posts
But...
Why would you set the priority such that a hidden layer's wall interferes with a visible layer's walls?

As I see it...(correct me if I'm wrong) if a wall is not visible, it shouldn't be interfering with those that are visible. It is a bit of a hassle prioritising layers that are turned off everytime you want to set up layer combinations for different design solutions.

waste of time? If it is turned off... I don't want it there

I think it is a non desired effect of an useful function…

Hard to explain with my poor English…
This function makes it possible the visible walls not to interfere between them…
Before, two walls in the same height and altitude will obligatory interfere with bad design :
for example a wall structural with fill and a low wall of terrace without fill.

After you just set them in two layers with different number of priority…

You may also want that two walls of different "nature", "purpose" or "materials" don't interfere in plan…

I hope that I am clear in my explanation, but I am don't sure…

For me it is a good function with "little" disagreements…

very well put! i agree that the usefulness of the priority-based layers system far outweighs the little 'quirks' that you find from time to time.

two things spring to mind here:

1. there is a useful add-on called 'intersection in combos' that helps clean up your existing layer combinations in order to avoid this issue. it can be found in the 'goodies' folder and loaded, as usual, with add-on manager. from the 'read me':

Intersections wrote:
As a result of this ArchiCAD Add-On, layer combinations will emulate the visibility-based intersection cleanup logic of earlier ArchiCAD versions.

In ArchiCAD 8 and subsequent versions, intersection cleanup is linked to the Intersection Group Numbers assigned to layers. If the layers of visible elements have different Intersection Group Numbers, the connections of these elements will be not cleaned up.

With this Add-On, you can automatically assign a Group Number of 1 to all visible layers and a Group Number of 0 to all invisible layers registered in Layer Combinations. From then on, activating a Layer Combination will always deliver clean elements intersections. Layer combinations of old projects can then be used as before.

Important: Any Intersection Group Numbers you have already set up in this project will be overwritten.

2. when you do get little "disagreements" such as this, it helps to highlight areas of your template or methods that aren't quite working as well as they could be . . .

Where does one find this useful-sounding add-on?
