FluidCAD

Parametric CAD for everyone. Write JavaScript. See 3D geometry in real time.

See it in action

From interactive viewport input to parametric history — a closer look at what makes FluidCAD different.

• Navigate Your Modeling History: Step through your feature tree one operation at a time. Review how any model was built and roll back to any point — no destructive edits.
• Mouse-Driven Prototyping: Extrude regions by dragging in the viewport. Get to the right shape faster, then lock in the values with code.
• Feature Transforms & Patterns: Apply linear and circular patterns to entire feature sequences. Mirror, rotate, and repeat complex geometry from simple building blocks.
• STEP Import & Export: Import existing CAD models or export your designs with full color support. Works with every standard CAD tool.

CAD by Code as it should be

A complete toolbox for parametric CAD. From first sketch to final export.

• Traditional CAD Workflow: Sketches, extrusions, fillets, shells, booleans, and more. A modeling workflow familiar to CAD users.
• Smart Defaults: Most operations just do the right thing. extrude picks up the last sketch, fillet targets the last selection, touching shapes are automatically fused — less boilerplate, more readable code.
• Shape References: Reference faces, edges, and vertices of other shapes directly. Minimal math, maximum clarity.
