The connection point needs to point into the direction of a Revit reference plane (orientation of the Z-Axis). The exact placement (intersection of 3 reference planes in the Revit Family Template) is defined in the interface configuration.

In order for a component / assembly to be able to be placed in Revit, at a certain position in the family, an eCATALOGsolutions connection point with adequate orientation has to be created in the project geometry and to be published via CNS classification -> class Placement Coordinatesystem (CNS_CP). See Section 3.5.4.2.2.4, “Classify placement connection point”.

In the case of geometrical variants the connection point must always hold a fixed position / orientation.

In the case of independent 3db files (for different LOG variants), the connection point has always to be at the identical, logical position within the geometry / the assembly.

For assemblies it is important that the part which contains the placement connection point is always available.

In assemblies, the placement connection point may not be in the "dummy starter part", as it is normally not exported into the CAD (dialog Part properties -> No export), thus not available within the assembly.

Only ONE Family Template may be assigned per eCATALOGsolutions project and only ONE placement connection point per 3DB (in the case of multiple 3dbs in a project).

If multiple 3db files have to be assigned to a project, please make sure that there are not more "CNS_CP" assignments than 3db files.
