Chat with design agents inside Civil 3D, Revit, OpenRoads, Navisworks, Tekla, and Dynamo — from the EnginAIer desktop app. Download the app from this site, add plugins inside the app, restart your CAD software, and work in plain language.
Download the EnginAIer desktop app from this site, then add CAD plugins inside the app — not here on the website. Restart your CAD software and chat from EnginAIer. This site handles your account, billing, and downloads only.
Install the EnginAIer desktop app and create an account. Auth, credit, and billing run through the website — no local database or command-line setup.
In the EnginAIer desktop app, open Download plugins, scan your PC, and click Install for each product. Plugins register in your CAD startup folders automatically.
Close and reopen the CAD application. There is nothing to load by hand — no NETLOAD, no add-in manager. A green dot on the software pill means EnginAIer is live.
Pick the connected pill, describe what you need, and send. The agent plans the work and runs the right tools directly in your drawing or model.
Plugin install buttons live only in the EnginAIer desktop app. This section is a walkthrough of what to do after you download the app.
This website does not install CAD plugins. Download EnginAIer here, sign in, then open Download plugins in the app sidebar to scan your PC and click Install on each product card.
In the EnginAIer desktop app sidebar, click Download plugins (or the gear icon → Download plugins).
Open the Detect software tab and click Scan. EnginAIer finds the CAD products already installed.
On the Download tab, click Install on the card for each product you use. Install only what you need.
Open the Status tab to see installed plugins, or Uninstall and reinstall if something needs a reset.
No manual NETLOAD, add-in manager, or copying DLLs. Each plugin registers itself in the folder your CAD software already reads on startup — a plugin bundle folder for Civil 3D/AutoCAD, an add-ins folder for Revit, a plugins folder for Navisworks, packages/Libraries for Rhino and Grasshopper, a packages folder for Dynamo, and an extensions folder for Tekla Structures. If a product can't be registered automatically, its plugin card tells you exactly what to do instead.
Plugins are stored under %LOCALAPPDATA%\EnginAIer\plugins on your machine.

Once a product shows a green dot, you're talking directly to that CAD session.
Click the pill for the app you want, e.g. Civil 3D. It must show a green connected dot.
e.g. "List alignments in this drawing" or "Read the road layout for Alignment 29."
Press Enter or click send. The assistant plans the work and calls the right tools.
The assistant runs tools in your CAD software and replies with what changed — check it before you rely on it.
Browse ACC hubs and projects, and hand the assistant a PDF or model straight from your project files.
In the sidebar, under Autodesk ACC, click Connect.
A browser window opens — sign in with your Autodesk account. This is separate from your EnginAIer login.
Back in the app, the ACC file browser opens in the sidebar. Pick a hub, project, and folder to find your files.
Select a PDF or model and attach it to your message — the assistant reads it directly for sheet reviews, specs, and coordination context.
Not connecting? Click the ACC button again to reconnect — the status dot turns green and shows your Autodesk username once it's live.
When Rhino, Grasshopper, or Tekla is connected, a sync bar appears below the software pills with per-app connection dots and one-click actions — frame Rhino views on the building, build a parametric Grasshopper canvas from a Tekla pull, or push/pull geometry between the two, no typed commands required.
👎 Report an answer that isn't giving you what you need. Every assistant reply carries a report control. Reporting sends that conversation to our team so we can investigate and fix it — and it's the only time a conversation is retained on our servers. Ordinary chats are relayed to generate a reply and never stored; a reported one is kept only until we've reviewed it, then its content is deleted. See the Privacy Policy for the full picture.
One agent per platform — Civil 3D, Revit, OpenRoads, ACC, Navisworks, Tekla, Dynamo, and more in the desktop app. Chat lives in the desktop app only; the website manages your account.
Everything in one place — horizontal layout & polylines, alignments & profiles, pipe networks, plan sheets, and rail design tools.
Element parameters, views, sheets, tags, and clearance checks — read and write Revit model data from chat.
Alignments, terrains, vertical profiles, corridors, templates, drainage and drafting in OpenRoads Designer.
Browse ACC project files, select a PDF or BIM model, and chat against it — sheet reviews, specs, and model coordination context.
Clash detection, ACC issues, and model coordination across Civil 3D, Revit, and Navisworks Manage.
A release is listed as Available only after the plugin has been installed into a real copy of that product and year, loaded on its own, answered on its pipe, and run a real command whose effect we confirmed. Everything else is marked Coming soon.
Drafting, alignments, profiles, corridors, pipe networks, and plan sheets.
Element parameters, views, sheets, tags, and clearance checks.
Clash detection and model coordination. Manage edition only.
Graph automation inside Revit, Civil 3D, or Dynamo Sandbox.
Alignments, terrains, proposed profiles, corridors, and drafting in OpenRoads Designer.
Structural modeling, connections, and drawing production in Tekla Structures.
NURBS modeling, structural sync, and mesh workflows in Rhinoceros.
Parametric design inside Rhino — live graph editing from chat.
What these labels mean. Available — All three criteria of the verification bar were met on a real install of this exact product and year, and the evidence is recorded below. Coming soon — Not installable yet.
Navisworks work targets the Manage edition; Navisworks Simulate is out of scope and Navisworks Freedom has no plugin API, so it can never be supported. Releases 2023 and earlier of the Autodesk products above are out of scope. Dynamo runs inside Revit or Civil 3D, or as Dynamo Sandbox. The desktop app labels every install card with the same status shown here.
No — not your drawings, models, or ordinary chat. EnginAIer is built local-first: CAD tool calls run on your machine through the plugin. The cloud only relays chat text to generate a reply, then discards it.
%LOCALAPPDATA%\EnginAIer\pluginsOne exception — when you report an answer. If you use the report control on a reply, that prompt, the reply, and the turns leading up to it are sent to our team so we can investigate. We delete the conversation content after review and keep only the rating, your comment, and basic metadata. Answers you do not report are never retained on our servers.
Pay monthly or yearly for a token allowance. Organization plans share one pool — unlimited members, no per-seat fees.

Plans are priced in USD credit. Usage is metered in real Anthropic input/output tokens (model and message length affect how fast credit is used). Estimates assume Sonnet 4.6 and a typical agent chat mix.
The same answers your EnginAIer administrator would give you — most connection issues come down to one of these.
Confirm the CAD application is open with a drawing or model loaded, and that you restarted it after installing the plugin — a session that was already running never picks up a plugin installed mid-session. Then click the refresh icon next to the software badges.
Check your internet connection, then close and reopen EnginAIer. If it persists, the cloud service may be under maintenance — contact your administrator.
This is almost always the same root cause as a grey badge: the plugin was installed while the software was already running. Close the CAD application, reopen it, then refresh the badges.
In the EnginAIer desktop app, open Download plugins → Download, click Uninstall on the plugin card, then Install again. Restart your CAD application afterwards.
Click the ACC button again in the sidebar — it reopens the Autodesk sign-in page in your browser. Make sure you complete sign-in in that browser window rather than closing it, then return to EnginAIer; the status dot turns green once the connection completes. ACC sign-in is separate from your EnginAIer account, so use your Autodesk credentials there.
No. Your drawings, models, and CAD data never leave your machine — every tool call executes locally through the CAD software's own APIs. Only the text of each chat turn (your message, the assistant's reply, and tool results it needs to continue) reaches our cloud service, and it is relayed to the AI provider and discarded, not stored. See the Privacy Policy for the full breakdown of what stays local and what doesn't.
That specific prompt and reply — plus the turns leading up to it — are sent to our team to investigate. This is the one exception to "we don't store your conversations": once we've reviewed the report, the conversation content is deleted and only the rating, your comment, and basic metadata are kept. Answers you don't report are never retained.
Windows 10 or 11 (64-bit), an internet connection, and at least one CAD product the plugin supports — nothing else. No database, no Node.js, no command line; everything is bundled in the installer.
