Appearance
Files & the page viewer
The Files panel is your table of contents for the whole drawing set, and the page viewer is where you read any single sheet. Together they're where you spend the first part of every project — finding the steel and getting to know the drawings.
The Files panel
Open it with the sheet-stack icon in the sidebar. It lists every page in the contract PDF.


List or thumbnails
Two view toggles at the top switch how pages are shown:
| Icon | View |
|---|---|
| List | A compact, scannable list. |
| Grid | Thumbnails, so you can recognise a sheet by sight. |
Pages grouped for you
The copilot sorts the pages into meaningful groups, each with a collapsible header (the chevron folds it):
| Group | What's in it |
|---|---|
| General notes | The written notes and specification sheets. |
| Steel structures | The structural steel drawings you'll build from. |
| Needs review | Pages the copilot wasn't sure about — worth a look. |
| Unreadable | Pages it couldn't read. |
| Filtered out | Pages that aren't relevant. |
| Unclassified | Anything not yet sorted. |
Working with a page
- Open a page — click it, or drag it into the editor (including into a split group).
- Right-click a page for its menu:
- Open, Open to the Side, Open at Bottom
- Copy page number
- Re-classify — Mark as Steel structure, General notes, Filtered out, or Needs review, if the copilot got it wrong.
Re-classifying is how you correct the copilot: if a steel sheet landed in the wrong group, move it, and it's immediately available to build from.
The page viewer
Opening a page shows it in the page viewer. It handles both scanned images and native vector drawings, with smooth zoom and pan.


The zoom bar
A floating toolbar gives you:
| Icon | Control | Shortcut |
|---|---|---|
| Zoom out | Zoom out (shows the current %) | − |
| Zoom in | Zoom in | + |
| Fit | Fit the page in the pane | F |
| Pin | Markup — pin a note or drag a box | M |
| Shapes | Regions (vector drawings only) | — |
Markups
Turn on Markup and you can:
- Click to drop a pin, or
- Drag to draw an area box,
then type a comment in the popover. Markups stay with the page, so you can leave notes for yourself or a reviewer right on the drawing. Editing page notes works the same way.
Handy while marking up:
| Shortcut | Action |
|---|---|
| M | Toggle the marker |
| Esc | Cancel / close the comment |
| ⌘/Ctrl + ↵ | Save the comment |
Regions (vector drawings)
On native vector sheets, the Regions tool lets you outline a part of the drawing — a single framing plan, say — and build a scene directly from it. That's the bridge from a drawing to the scene editor.
The page panel: AI Findings, Notes & Markups
Along the bottom of the viewer is a panel with three tabs (click the active tab to collapse it, and drag its top edge to resize):
| Tab | What you can do |
|---|---|
| AI Findings | See — and correct — what the copilot read for this sheet: its Sheet ID, Title and Reason, plus a classification dropdown. Editing here is a second way to re-classify a page and fix the copilot's read; Save changes to keep it. |
| Notes | Add as many page notes as you like, each one individually editable and deletable. |
| Markups | A list of every markup on the page — edit its comment or delete it, right from the list. |
The right-click menu
Right-clicking the drawing gives you quick actions: Add markup here, Re-cluster (when there are several steel pages), and Fit page.
Next
With the steel pages sorted, let the copilot read them, or jump straight into the scene editor to start tracing.
