# How to create helix around cylinder or cone

Hi,

I would like to create an helix around a cylinder or cone. I saw it was possible to create directly an helix spline around the cylinder surface but don’t find how to do it, is somebody could explain it to me ?

@Cdaum Hi welcome to the S3D Forum
A great place to find out ‘how to’ in S3D is by searching the Forum.

Here is link to just one of many Threads on this subject:

If you still need help please do let us all know.

The method that I talked about is this one, describe on the first post here :
https://discourse.shapr3d.com/t/spiral/1441/2

How can I do that ?

Thanks

@Cdaum
Sketch a Circle > Add > Construction Plane > Perpendicular to Curve a Point [this is shown selected for clarity]:

Select the Light Blue Circular Shape > Pull up to the desired height [In this case 10mm]

Double Tap with your Finger on the Construction Pane [CP] [zoom in so that you can hit the target accurately, you can Scale the CP as required]
Sketch > Circle from Centre [used in this case but you can use any Closed Shape to Extrude or in contact with the Cylinder to form a Mark/Groove/whatever] ] in the desired position on the CP

Add > Construction Axis > Through a Cylinder or Cone:

Tools > Revolve > Select the Circle sketched on the CP [zoom in to the Circle or tap on the Navigation Cube top right to orient the Design into 3D if necessary to achieve the ‘highlight’] > Next > Select a Line or Edge for Axis > Hit the Added Axis

In the Dialogue Box top Left tap the ‘0’ under Height > Input in 10 or destination height needed then Hit the Green Checkmark area [the resulting Body has been coloured Red for clarity]:

If e.g., you need two revolutions change the Angle to 720º, and so on.

Thanks for the method but it doesn’t work for creating a conic helix or conic sprint, is it an easy way to create a conic helix drawing, and then use it for a sweep ?
