...maybe I should switch to "Direction" mode for the "Project" command.

But I wanted to use "ClosestPt" because it's more easy and requires less interaction with the user, less inputs from him.

I think if I switch to "Direction" for "Project", if I want to keep the code simple at least for this first upcoming official release of the script,
my command will work only for Top Plane.

Instead using "ClosestPt" I've seen that it works also for all standard planes (right, left....)

I don't know.

Also I'm writing this script to be placed in "Scripts" folder, non in "Commands" because I don't want for it any UI.
Just fire a shortcut and run it, both Lasso and "FindHoles" variants.

What do you think ?

Thanks.
