📝 How to do it yourself

Type HELIX and press Enter.
Pick the centre and the base radius.
Enter the top radius — use 0 for a cone-shaped spiral.
Enter the height and press Enter.

ℹ️ What HELIX actually does

Draws a 2D or 3D spiral with a base radius, top radius and number of turns.

When to use it

Use it as a path for SWEEP to model springs, spiral stairs, handrails and coiled elements.

⚠️ Common mistakes

Forgetting the helix is only a path — it needs a profile and SWEEP to become a solid.
Setting turns too low and getting a stretched, unreadable spiral.
