About the "Intersections in Layer Combinations" Add-On

INTRODUCTION

With this Add-On you can assure that visible building elements do not interact with invisible building elements.

In ArchiCAD 8 and subsequent versions, intersection cleanup is linked to the Intersection Group Numbers assigned to layers. Elements which belong to layers having the same Intersection Group Number will intersect, regardless of layer visibility. Elements which belong to layers having different Intersection Group Number will not intersect. The Intersection Group Number of layers are stored with Layer Combination, so the same layer can have a different Intersection group Numbers in different Layer Combinations.

With this Add-On, you can automatically assign Group Number "1" to all visible layers and a Group Number "0" to all invisible layers registered in Layer Combinations.

Important:

Any Intersection Group Numbers you have already set up in this project will be overwritten.
Changing layers one by one may still result in visible elements without clean intersections.

HOW TO INSTALL "Intersections in Layer Combinations" ADD-ON

Start this installer and follow the instructions. The add-on will be automatically loaded the next time you start ArchiCAD.

The new command will appear in the "Options" menu by default.
