I've been searching for here and cannot find nothing about it.

I need to replicate this sentence with matrixes:
in coordsys $Node2 move $Node1 <point3>
This is the solution I get:
$Node1.transform = translate $Node1.transform (transMatrix <point3> * $Node2.transform).translationpart
I guess there will be a cleaner way...
Thanks

Is this what you are looking for?

$Node1.pos += <point3> * $Node2.transform - $Node2.pos

A better way:
$Node2.pos += <point3> * inverse $Node1.transform
