MaxScript: How to Extrude Along a Spline

Quickwits92 · May 2012

Hello,

I'm using MaxScript for a uni module and my idea to create a scene generator. I'm keeping it simple for now and sticking with just a hilly scene.

What I would like to know is how to create a road using maxscript. Ideally, I would like to be able to select a spline, then create a box at the start and have it extrude along the spline.

Thanks

Select a path or shape. ac.menuaro.gif

Create panel ac.menuaro.gif

(Geometry) ac.menuaro.gif

Compound Objects ac.menuaro.gif

Object Type rollout ac.menuaro.gif

Loft Select a path or shape. ac.menuaro.gif

Create menu ac.menuaro.gif

Loft

Or search in max reference compound loft.

Thanks but I'm looking to do this in maxscript so I need the code to automatically do this process

Don't you have to create the scene generator ? As in you ?

Yes, I'm writing code that automatically creates hills, trees, rocks, etc for the user. What I want is for the user to create a line on the plane that has been created and for them to press a button which will create a road along that line.

Does this help ? http://www.scriptspot.com/3ds-max/scripts/arrangement i haven't tried it or anything .

Thanks but I've managed to do that before but it struggles to work going round corners because it makes multiple boxes, it doesn't look smooth.

Back when I messed around with the Loft modifier, i ran into a brick wall because it's not exposed to scripting.. :-/

Yeah, you don't loft in MaxScript. That's why I want it to extrude along the spline. That I know you can do, I'm just not sure how.

So dude i recorded with the max listener and this is what i get.
$.EditablePoly.SetSelection #Face #{2}
macros.run "Editable Polygon Object" "EPoly_Extrude_Along_Spline"
$.extrudeAlongSplineNode = $Line001
$.EditablePoly.ExtrudeAlongSpline ()
Can you make it to get the face that forms the road section and the line that user wants and make the script ?
And yes you are right it uses the extrude along spline.

Ah, thanks a lot

I can use that, I just need a way to place the box on the end of the line to start off with...

getKnotPoint <shape> <spline_index_integer> <knot_index_integer> use this to get
the coord of the first vertex(knot) in the line and move your box to that point ?

Thank you!

Last thing to do now is to make my road mold to the plane...
