Use layers to prevent intersections

Intersecting elements that belong to the same Layer Intersection Group will connect to each other, provided they are drawn correctly.

Exception: Two elements that are both set to intersection group 0 will NOT intersect.

By default, every layer is set to Group 1, so all intersecting elements will be joined according to the regular connection rules for Archicad.

Prevent element connections: Assign different layer intersection groups

You may want to prevent element connections - for example, to show the details of composite walls. In this case, place the intersecting walls on different layers, and then give one of these a layers a different Layer Intersection Group number. Elements on different Layer Intersection Groups will not connect.

1.Open Layer Settings (Document > Layers > Layer Settings)

2.Select the layer of one of the intersection elements.

3.Edit the value under the intersection icon.

Wall Layers Have Different Intersection Group Numbers: No Connections

Note on intersection with hidden layer: Elements having identical intersection groups will intersect even if one of the layers is hidden. This may result in “missing” lines, indicating an intersection with an element on a hidden layer. To avoid this, go to Layer Settings, select one of the layers, and assign it any different intersection group.

Note: Layer Intersection numbers have nothing to do with element priorities; they serve merely as tags for grouping elements.
