How it works

Three steps to automated CAD

From lane layout to pipe networks to plan sheets — one agent handles it all in Civil 3D.

1

Open the Civil 3D Agent

One agent in the dashboard — drafting, utilities, profiles, sheets, and rail. No picking between Pipe vs Drafting vs Sheet.

2

Start one plugin

NETLOAD TwinThread.C3D.UnifiedMcp.dll — pipes auto-start. Restart: TT_MCP_AGENTOS.

3

Ask in plain language

"Draw 4-lane polylines for alignments 4–7", "create storm network Main", "match this sheet sample" — the agent picks the right tools.

Design agents call MCP tools. MCPs generate AutoLISP, .scr, DST. Civil 3D executes.

Pricing

Token pools for individuals & teams

Pay monthly or yearly for a token allowance. Organization plans share one pool — unlimited members, no per-seat fees.
