Modelling

How to build a model by hand in the Womp editor, and where to read about each part.

Use this when: you build or edit a model by hand in the 3D Stage, or need to know which modelling page answers a question.

Don't use this for: AI generation or node graphs. Read Spark (Womp AI) and Flow (Nodes).

In Womp you model with simple shapes. You add shapes inside an area, and set how they combine: they can blend (Goop), cut each other (Form), or reflect (Mirror). Womp saves your project automatically. There is no save button.

How a model is built

  1. Add a shape with O (Open objects menu).
  2. Move, rotate and scale it with the handles on the canvas, or type values in the inspector.
  3. Add more shapes to the same area. Put shapes in a union to treat them as one object.
  4. Set Goop to blend them, or set Form to Negative to cut.
  5. Check the order of objects in the scene list. An object changes only the objects above it in the same area or union.

Pages in this section

  • Navigation and layout: move the camera, switch views, and use the scene list and the inspector.
  • How Womp builds a model: solids combined in order, Goop as a blend, and why Areas decide what can blend.
  • Shapes and Goop: the shapes you can add, the handles, and how Goop blends shapes.
  • Scene list: areas and unions, the order rule, and the Health and Imports tabs.
  • Form and Mirror: Positive, Negative, Stain, Intersect, Mirror, Flip, Align and Lattice.
  • Keyboard shortcuts: every shortcut from the editor's shortcut list, plus undo and redo.

Use instead

  • Wrong move: modelling a part for print without checking the print limits. Why: thin walls and tight gaps can fail. Right move: check Design rules while you model.
  • Wrong move: putting a Negative object above the shape it should cut. Why: an object changes only the objects above it in the same area or union. Right move: move the Negative object below the shapes it cuts. See Scene list.
