The workspace

Opening a project drops you into the workspace — the home base for everything you do in Fablnx. It's laid out like a modern code editor: a top bar, a left sidebar, a tabbed editor area in the middle, and the AI copilot on the right.

The top bar

Running across the top:

Icon	Control	What it does
Back arrow	Back to projects	Returns to the dashboard.
Panel	Show / hide sidebar	Collapses or reveals the left sidebar. ⌘/Ctrl + B
Sun / Moon	Theme	Switches between light and dark mode.
Speech bubble	Copilot	Shows or hides the copilot panel. ⌘/Ctrl + J

The centre of the bar shows the contract filename so you always know which drawing set you're in.

The left sidebar

The sidebar has four panels, switched with the icons down its edge. Each has its own page in this guide:

Icon	Panel	What's in it
Sheet stack	Files	Every page of the drawing set, grouped and searchable.
Model cube	Build	The scenes you're tracing into the model, plus Coordinate model →.
Document	Design spec	The steel design notes the copilot extracted.
Warning bubble	RFIs	Validation issues and open questions.

The editor area

The middle of the workspace is a full tabbed editor, just like a code editor. Tabs can hold a page, a scene, or the model.

• Multiple tabs — open as many pages and scenes as you like and switch between them.
• Reorder — drag tabs along the strip to reorder them.
• Split views — drag a tab to the side or bottom of the editor to split it, so you can see a drawing and its scene side by side. Drop zones appear labelled Move here, Split right and Split down.
• Close — click the × on a tab, or middle-click it. Right-click a tab for Close, Close Others, Close to the Right, Close All, Split Right and Split Down.

You can also split from the tab strip buttons: Split right and Split down.

Resizable groups

Once you've split, drag the divider between editor groups to resize them, and use the keyboard to jump focus between groups (see shortcuts below).

Quick Open

Press ⌘/Ctrl + P to open Quick Open — a command-palette that lets you jump to any sheet, page or scene by typing its name or number. It's the fastest way to move around a big drawing set.

Keyboard shortcuts overlay

Press ? anywhere in the workspace to open the keyboard shortcuts overlay — a cheat-sheet of everything you can do from the keyboard.

The essentials:

Shortcut	Action
⌘/Ctrl + B	Toggle the Files panel
⌘/Ctrl + J	Toggle the copilot
⌘/Ctrl + P	Quick Open (go to page…)
⌘/Ctrl + \	Split right
⌘/Ctrl + 1–9	Jump to a tab
?	This overlay

The full list lives in Keyboard shortcuts.

Where to next

• Read and mark up drawings in Files & the page viewer.
• Watch the copilot identify the steel and extract the spec.
• Start building in the scene editor.
