This section explains how to create a tension spring.
When using the Parasolid modeling kernel, it is not possible to create a tension spring without any gaps.
A slight gap is required.
Also, when placing a helix in space, the anchor point of the part is not created at the center of the helix.
You will need to use some tricks, such as temporarily placing a reference part.
Procedure:
[1] Place a "Block" as a reference part so that the anchor of the spring is created at the center.

[2] Click [3D Curve] on the [3D Curve] tab.

[3] Click [Helix] on the [3D Curve] tab and place it on the reference part.

[4] Enter the parameters and click [OK].
Then, click [OK] again to exit the [3D Curve] editing mode.
[5] Go to the [Feature] tab → [Feature] group → click [Sweep Wizard].
When you select the created [Helix], it will switch to creating the cross-sectional shape.
[6] in the [Sketch] tab → Drawing Group → click [Center Radius], then create a circle.
Set the diameter of the cross-sectional shape smaller than the [Helix Pitch] to allow for a gap.
In this example, the start pitch [p1] is [20], so the helix pitch becomes 20/2 = 10.
Therefore, set a value smaller than [10].
[7] Suppress or delete the block and 3D curve used as references.
Please refer to the video below.
