Hi OSTexo.

Well... if I understand correctly, you're trying to do the same thing that I discussed some month ago with my thread
"Lightweight Modelling. A case study." (http://moi3d.com/forum/index.php?webtag=MOI&msg=8135.1)

Here I post now a complex and slow, but good solution to achieve one of that tasks, that is :
construct an offsetted control point curve in a lightweight way, to get almost the same topology of the source curve.

I hope that this material may be useful for someone.

A great think could be to write some sort of script that should do automatically all that manual steps.

Here's the video tutorial I created. It's 155 Mb so if you have a slow connection maybe it's better to download it first.

And this is the script I wrote some time ago, ExtractCurvesControlPoints.js:

(it's based on one Max's script).

Place the .js file into the "C:\Program Files (x86)\MoI 3.0\commands" (for windows users).

Please, let me know what do you think about my tutorial.

See you.
