Helix

This command allows you to create a helix or a spiral.

Creation Stages / Use:

Select the 3D sketch > Operations > Helix... command from the drop-down menu.

Select the Frame for creating the helix/spiral.
Enter the value of the start radius of the helix/spiral.
Enter the value of the radial pitch of the helix/spiral (this value must be null in the case of a right helix).
Enter the value of the longitudinal pitch of the helix/spiral (this value must be null in the case of a flat spiral).
Enter the minimum number of turns of the helix/spiral.
Enter the maximum number of turns of the helix/spiral.
Validate the creation of the helix/spiral with the button.

Available Options:

Invert Z:

By default, the helix is created along the Z + axis of the selected frame, this option allows you to create the helix along the Z- axis.

Invert Z option unchecked	Invert Z option checked

Go inside:

In the case of a spiral, the radial pitch is applied by default towards the exterior of the spiral, this option allows you to apply the pitch towards the interior of the spiral so that the spiral is re-centered toward its creation axis.

Left handled:

This option inverts the direction of travel of the sketch (right pitch or left pitch).

Additional Information / Modifications:

Click the yellow handles to quickly and dynamically modify the radius and pitches of the helix/spiral or double-click the labels to enter the values of the radius and pitches of your helix/spiral:

1. longitudinal pitch

2. radial pitch

3. starting radius

The Tolerance contextual command allows to modify this approximation.
