[Closed] Outline spline

I really don`t make scripts but mostly use the macro recorder to make predefined editors for the project i am working on.
My problem now is i need to make a little script that makes:

1. You draw a spline
2. it makes a wall on the spline when you finish it.

It doesn`t need to make the wall just right away i can make it with a button. But my main problem is i want to make an outline of the spline that is selected.You know the outline tool under spline edit. I can get in the outline mode with

splineOps.startOutline

when the subobj level 3 selected. but i want it to be automatic in a predefined thickness. After that its really easy to make the wall extrudes.

Thank you

PS: max 5.1. And no “Game Level Builder2.2” doesnt work in my situtation because we have much smaller unit system and units and i dont think we need a complicated thing like that just a simple solution is good because its just for testing. I will build the real model later.
