Parametric 3D modelling driven entirely by code rather than direct manipulation.

PriceFree

PlatformsWindows, Mac, Linux

Why we recommend it

You describe geometry in a scripting language instead of drawing it, which makes designs genuinely version-controllable and trivially parameterised — powerful for functional parts.

Strengths

Fully parametric — change a variable, regenerate the model
Plain-text files work properly with Git
Excellent for functional and mechanical parts

Keep in mind

No direct manipulation at all — everything is code
Organic or sculpted shapes are impractical
Preview rendering slows badly on complex models
