# Spiral with a shape

Hi, need help with projecting a shape onto a spiral.

that does not describe it well enough for me at least, can you try to elaborate a bit more?
it looks like you are trying to sweep it rather then projecting, but i can not say for sure.

Are you wanting to spin that down the length of the spiral? If so rail revolve may get you there

It does - assuming you do want the wave to get shorter as it goes down:

Sweep2 works as well, and seems to calculate a little more quickly:

Sweep1 with the Roadlike option allows you to keep the wave a constant length all the way down, the bottom then looking like this:

Whatever you want to do here, Iâ€™d recommend using Rebuild on the spiral to cut down the number of points and simplify it before manipulating the wave against it.

What I need it the â€śsnailâ€ť shape to be the spiral. Sweep and Flow donâ€™t work.

I donâ€™t really need it to be solid. Imagine it as a metal spring, but in a shape of a snail, doing down.

Sorry, I have no idea what you mean by that.

This maybe?

Or this?

Or?

Edit: Hmm. I like @laurent_delrieuâ€™s suggestion. Hope that is what you mean. Fingers crossed.

This is exactly what I need! Do you mind sharing the commend you used?

my guess is he made a very long wavy curve and a spiral, then used flow

pro tip, you can use DimCurveLength to get the actual length of your spiral, then make you wavy curve the same length before you flow, that will avoid any distortion youâ€™d get by having the flow option stretch set to yes.

Sorry, you will need to tell me which oneâ€¦

that one should do either, less to type

The first one Jeremy. Thank you!

As @theoutside surmised, I used flow along curve (_Flow). Just to clarify one thing he said: making the length of the wavy curve the same as the length of the spiral means making the baseline length (ie the straight line length from one end to the other) the same as the spiral, not the curve length of the wave.
