Call up the context menu command New rule on the attachment point of the dummy start part (cp_dummy_traeger).

-> The Rule properties dialog box opens.

Select the support (din_1025_s) as the connection part and IP1 as the connection point.

Activate Reverse direction and Exclusive, select Allow automatic assembly [Permit automatic build] in the list field.

Insert the carrier in the docking window Structure [Assembly].

At the moment, an error message still appears because it is not defined which characteristic of the carrier should be selected for which table line in the dummy start part. The assignment between the two tables is missing.

No valid table row selected [No valid table line selected] - MIDENT

The problem is solved by inserting a corresponding condition. See next section.
