Prompt to CAD

Tell it what you need. It writes the code.

Type a natural-language prompt and the Agent generates LCD code that compiles to parametric geometry. You review every change before it lands.

Unified Canvas

2D plan and 3D model in one view

Plan view, 3D perspective, and cross-section from a single parametric model. One geometry kernel, one source of truth.

LCD Language

Code that reads like a spec

LCD is a domain-specific language for construction geometry. Write it by hand, or let the Agent write it from a prompt.

Plan Mode vs Edit Mode

Plan Mode

The Agent reads the brief, analyzes room geometry, checks the knowledge base, and proposes a step-by-step layout plan. Nothing changes until you approve.

Edit Mode

The Agent writes LCD code directly. Every line enters the review queue as a ChangeEntry. Accept, reject, or revert — granular control over every modification.

Prompt → Code → Geometry → Drawing

Describe

Tell the Agent what you need in natural language.

Generate

Agent writes LCD code. You review the diff.

Validate

Rules engine checks spacing, clearance, coverage.

Export
