For the "Pipe clamp" (RS) component, click on the context menu command Insert condition under Conditions.

-> The Condition properties dialog box opens.

In above area select that part for which the condition shall apply (here KP1).

Enter name and conditions.

T@B = RS@NR

That means: The width (B) of T-beam (TB) shall meet the value of variable NR of the pipe clip, where NR has a unique value for each row and thus codes all possible further attributes such as type of the pipe clip, bore, pipe diameter, etc.

Confirm with OK.

-> The condition is displayed with the name assigned in dialog and if-icon.

-> The 3D view currently looks like this.
