Spring

Procedure

1. Click Spring in the Physics section of the ribbon bar.

2. Hover your cursor over the 3D area. A guide plane appears beneath your cursor, helping you select the cylinder's placement. Left-click to confirm the location.

3. Move your mouse left or right from the spring's center to adjust its pitch radius. Moving outward increases the size, while moving inward decreases it.

4. Click to validate the spring’s pitch radius.

5. Move your mouse up or down to adjust the spring's height.

6. Click to validate the spring's height.

7. The spring is created, you can refine the property values from the Object properties panel.

Properties

The spring's pitch radius, height (along the Z-axis), wire radius, and coil count are its primary properties, measured in meters. The wire radius must be 0 or greater; entering negative values prevents the spring from rendering. When you enter a negative height, the spring extends either in the positive or negative Z direction, depending on where its frame origin is located (bottom, center, or top).

The spring's frame origin defaults to the bottom face (the spring's base). You can also set it to the top face (opposite side) or the center (midpoint of the height).
