Altium Design Rule - How to apply to one named component?

Question

How can I build an Altium Designer rule that applies to only one component or reference designatorrefdes?

I tried selecting my component, S1, from the Query Helper, but that just puts the string 'S1' into the query. What else belongs there?

Answer 1

It's InComponent(), i.e.:

InComponent ('J2') OR InComponent('J3') OR InComponent ('J4') OR InComponent ('J5')

Likewise, if you end up making a ComponentClass, it's InComponentClass():

InComponentClass('WaivedClearance')

Remember that if you do a positional re-annotation or something similar at the end that changes reference designators, your rules and component classes won't update automatically.
