Hello Michael.

Ok. I will publish this first beta version of these two scripts in a new thread.

I'm doing some final test and I hope that in a couple of hours, starting now, I should be done.

Unfortunately, like you said, during the last tests the "ClosePt" method for the "Project" command is proving to be too unreliable in many cases.

But I want to close this first beta soon, so i think I should switch to "Direction" mode and calculate the direction based on the bounding box of the container curve.

This will take at least one hour to make some test.

@You : "...Are you sure you need to have it removed? Since there was some discussion there about possible strategies..."

I asked you to remove the other thread because I thought that all the most important things have been addressed here
and all the 5 posts there are only from you and me. No other users.

If you want you can remove it.

Now I go to make the final coding and test.

We'll catch up!
