Yes. This is how the distance tool does it. This is the command harvested from the script editor.

distanceDimension -sp 0 0 0 -ep 0 0 0 ;

This results in a dd node with locators attached. Very slick.


Compared to:

distanceDimension -sp $locWp1[0] $locWp1[1] $locWp1[2] -ep $locWp2[0] $locWp2[1] $locWp2[2];

These commands appear to be identical but they do not result in the same dd configuration.
So I have to use one of my clumsy methods.
