Dockable Claude chat palette inside Civil 3D
Overview
A Civil 3D plugin that adds a dockable WPF chat palette backed directly by the Anthropic Claude API. Streams responses token-by-token and grounds every request in the active drawing's own layers, TIN surfaces, and alignments so answers can reference real drawing state without the user typing it out. Strictly read-only — never creates, modifies, or deletes drawing entities.
What it does
- Dockable chat palette (PaletteSet)
- Streaming token-by-token responses
- Drawing-context system prompt (layers/surfaces/alignments)
- Read-only — no drawing writes
