Can I get Component2 from Refplane?

I want to get Component2 object, which a Refplane directly belongs to, track from a RefPlane object,

is there any way to do it?

I could cast up RefPlane -> Entity, but IEntity.getComponent method doesn't work from a plane entity

and now I have no idea what to try next.

The purpose is,

I'm writing a macro to check parallel from 2 planes.

Succeeded if the two planes in a part,

but in Assembly I find that I have to consider part itself orientation if the target plane belongs to a part.

Any kind of advice appreciated, I'll try.
