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.
To install "Intersections in Layer Combinations" Add-On, copy "Intersections in Layer Combinations" file into your designated Add-Ons folder (typically the Add-Ons folder in the ArchiCAD 11 folder). In this case, the add-on will be automatically loaded the next time you start ArchiCAD. Alternatively, you can save the Add-On anywhere on your hard disk, and load it through the Add-On Manager (Options menu).
