How do you extrude a shape along a path?

[Anonymous]

Hello.

I'm very new to 3DS Max. In the past I've used Google Sketchup & Blender but I have moved to 3DS Max because it seems to be superior.

I'm supposed to design a Race Track in 3DS Max, however there is one issue I'm running into.

I have created a Spline, which represents the course layout. Now the problem is I don't know how to extrude the unique road shape along it. (Basically the Odd road shape needs to move along the path to create the main route)

Could somebody explain how I do that exactly?

I cut my shape out with the mesh editor, and I have my path (Spline) ready, and now I need to extrude it along the path.

Anybody know?

you can use the sweep modifier.

I've already tried the sweep modifier.

It automatically generates geometry shaped like the path, not anything like I need.

Is there some step I'm missing perhaps? I need to extrude my special shape along the path to create my Race Track.

Sweep defaults to a built-in shape (cross section). Click "Use Custom Section", click Pick and select the shape you want in the Viewport.
