Questions
Is the whole CAD tool really free?
Yes. Modeling, sculpting, assemblies, unlimited physics, unlimited private files, and STEP + STL export are free forever. Paid plans add more capable AI, not core features, you never lose access to what you built.
What are convergence loops?
The AI iterates on your design, adjusting parameters and re-running physics, until it satisfies the constraints you set. This agentic loop is unlocked on Pro and above.
How is AI usage measured?
By AI actions and convergence runs, weighted by the model used. Each paid plan includes a generous monthly allowance; very heavy use may slow down or meter.
Which AI models do I get?
Each plan maps to a class of models, mini on Free, standard on Pro, frontier on Studio, and custom or edge-deployed on Enterprise. We map each class to the best model available and upgrade you automatically.
Can I use LessCAD commercially?
Free is for personal and non-commercial use. Pro and above include full commercial rights.
Billing is being finalized, paid plans currently start a free trial while we wire up checkout. Prices in USD. Model tiers reflect the best models available and may change as new ones ship.
