AI
NirTsCAD is AI-native. In the signed-in CAD tab, add your own Gemini API key under Settings and prompt from the AI panel — the assistant draws in your drawing. You can also connect Cursor, Claude, or Antigravity over MCP. Any product trial unlocks all current MCP tools. After the trial, Draw tools stay with Draw; slab, beam, and analyze need Buildings. Hydraulics MCP is coming later.
