Get node measurements

vision

Hi,

I'm realy new to DAZ-Scripting so sorry if this is a dumb question but I can't find what I need in the documentation.

I want to create a Script, that moves a node in a specific direction by his own length. For example to stack a group of similar object in a row. It's not the problem to move the object but how can I find out the x-, y- and z-length of an object.
