# spiral ramp

## Recommended Posts

I am struggeling to create a spiraling ramp in whatever way I tried so far. The helix-spiral tool looked promising, but resulted in a completely twisted surface.

To explain what I am looking for: To start with, take a multi storey car park which has a spiral ramp connecting it's various levels.

I referred the "Doorstopper" Tutorial, thinking that it was quite similar to what I was looking for. It works fine to extrude the circle along the spiral path, however, when I replace the circle with a rectangular object it twists the object while extruding it.

Any suggestions as to how to solve this? To me it seems like a fairly standard operation, so I presume there should be a pretty straight forward way to do this.

(Working on VW 11.5.1)

Thanks,

Use a sweep.

Draw the profile of the ramp and place a locus at the center of the sweep.

Select both objects and then run the sweep command.

Pursuant to klinzey:

Thanks!

That made my life a whole lot easier...

Best wishes,

Islandmon, once again you amaze me. How did you achieve the variable colored surface and the center stripe?

As always, thank you.

How did you achieve the variable colored surface and the center stripe?

There are actually two nested profiles; one for concrete and the other for asphalt surface which has a texture with the centerlines:

Thanks Islandmon. I never would have guessed that VW could take that straight image and curve it to match. I know that I sometimes get frustrated at what this program cannot do. It is times like this that I need to step back and stand in awe at what it can do.

Thanks again.

Islandmon. I have tried to recreate your example but I am stumped. I can create sweeps all day long. But how did you put a texture on your sweep object?

It appears that your object has a texture already and that you swept that. Putting a texture on the finished sweep is not the answer.

A polygon cannot take a texture and a 3D polygon cannot be swept.

You are a magician. I only hope that you will reveal your secret :-).

Actually, yes - you can render a sweep just as you would any 3d object. Either through the class settings or in the oip.

Just as jeffroyer states:

Assign a texture via 'Class' for each of the sweeps.

1) Create concrete poly profile & vertex>assign Class/texture to poly>sweep

2) Group>Duplicate>edit > create asphalt poly>assign Class/texture >delete concrete poly

3) Render

Islandmon: Thank you so much. I never would have figured it out without your help. Your contributions to this Forum make this "job" of using VW fun.

Kevin, thanx for your positive comment ... you make a very good point ... using VW should be fun !

Over the years I've tried to keep "this ' job ' of using VW fun" whenever possible. Heres a link to a few of my albums. Most of this 'fun stuff' was created using VW :
