No installs. No exports.

CADchat workspace with 3D canvas, documents, whiteboard, meeting, and folder tabs

3D Canvas

Any CAD file.
Instantly in your browser.

Drop in a CAD file and start reviewing in seconds — no plugins, no exports, no install for anyone you invite. The file-prep time disappears; the review starts now.

30+ formats

Drop it in. It opens.

Live collaboration

Everyone sees the same model, in sync.

Inspect every part

Explode, section, and isolate geometry.

Annotate in 3D

Pins, snapshots, and measurements — all threaded.

Draw on the model

Sketch directly on geometry for clarity.

Split screen

Model and drawings, side by side.

CADchat 3D canvas with live participants reviewing a model

Documents

Your drawings.
In the review.

Redline with precision, every comment pinned to the exact spot on the sheet. Nothing’s lost in a PDF email chain, and your markup never drifts from the drawing it belongs to.

Layer control

Toggle layers without touching the source file.

Precision markup

Redlines, dimensions, callouts — instantly visible.

Pins, snapshots & markup

Click anywhere. Comment in context. Start a thread.

Compare with 3D

Drawings and models, always aligned.

Reviewing and marking up engineering drawings in CADchat Documents

Whiteboard

Sketch ideas.
Align fast.

Sketch, map decisions, and brainstorm right beside the model — not in a separate app you’ll forget to open. And it’s all still there after the meeting, tied to the project.

Freeform canvas

Draw, type, and move fast.

Think together

Everyone contributes in real time.

Persistent context

Nothing disappears after the meeting.

CADchat whiteboard for sketching alongside the 3D model

Meeting

Meetings, built
around the model.

Stop screen-sharing CAD. Meetings start in the model itself, audio and video built in — so decisions get made in context and actually stick.

Start inside a Space

No setup. Click and go.

Built-in audio/video

No Teams or Zoom. No switching tools.

Calendar integration

Works with Google and Outlook.

Files

All your files.

Models, drawings, specs, and the decisions behind them — all in one Space. No more digging through email, Teams, or shared drives. No more building the wrong rev because the right one was buried.
