2D Profile Preview

Sweep Presets (Shape + Path)

Polar Cross-Section & Path

Use 'theta' (angle in radians).

Warning: Uses eval(). Be cautious with input.

Sweep Path: Parametric (x,y,z = f(t))

Defines the 3D path. Use 't' as the parameter.

Rotates the shape profile as it moves along the path. Use this to create threads, drill bits, or correct orientation.

Polar6

Create 3D lathe and polar-sweep shapes from formulas, presets, or freehand profiles, then preview and export STL, OBJ, or GLB.

What this tool does

Polar6 turns mathematical profiles, presets, or a freehand outline into a live 3D shape. It supports lathe revolutions, polar extrusion, path sweeps, parametric semicircle or ellipse profiles, and a 2D preview.

Who this is for

How to use this tool

  1. Choose a lathe, polar, parametric, or free-draw profile mode
  2. Enter a formula or select a preset, then set ranges, segments, depth, wall thickness, or twist as available
  3. Generate the shape and inspect the 2D preview and orbitable 3D view
  4. Download the current result as STL, OBJ, or GLB

Inputs

Inputs include profile formulas such as x, y, r, or t expressions, angle or parameter ranges, sampling and revolution segments, axis and sweep settings, depth, twist, hollow wall thickness, and freehand points.

Outputs

The tool renders a 2D profile and interactive Three.js geometry, then downloads the generated shape as binary STL, OBJ, or GLB. It does not save projects to an account or server.

Frequently asked questions

Which formula variables and modes are supported?

Lathe profiles use x and y, polar profiles use radius and angle, and path sweeps use x, y, z as functions of t. The page also includes parametric and free-draw modes.

Can I make a hollow lathed part or twisted sweep?

Yes. Lathe mode exposes wall thickness and partial-revolution controls, while path sweep mode provides twist and path settings.

Which formats can I download?

After generating a shape, use the export controls to download STL, OBJ, or GLB geometry.

Why might generation be slow or fail?

Invalid or non-finite formulas stop generation, and high segment counts can create heavy geometry. The page does not repair meshes or guarantee manifold solids.
