Engineering Workplace

The Engineering Workplace lets you mark up a standard while you read it — drawing, highlighting, adding notes, and leaving comments — and keeps your work saved automatically. The original document is never modified; your annotations live in a separate layer that's loaded back the next time you open the document.

If you're on a business subscription, you can choose to share specific annotations with everyone else on your subscription so they appear when your colleagues open the same standard.

Where to find it

The Workplace is built into the subscription reader in your E-Library. Open any standard your subscription grants you access to (My Library → standards list → open) and you'll see the reader with the document on the left and the Workplace side panel on the right.

It's available on subscription-based documents. Single-purchase E-Library titles use the plain reader without the Workplace layer.

The annotation toolbar

The viewer's annotation toolbar gives you three tools:

Tool	What it does
Draw (pen icon)	Freehand ink. Adjust color and thickness from the inline controls that appear while drawing. Useful for redlines, circles, arrows. After you stop drawing for about a second the stroke is committed automatically — keep adding strokes without pause to combine them into one annotation.
Highlight (highlighter icon)	Select text in the document, then choose a color. The highlight stays anchored to the underlying text. To add a comment to a highlight, click the highlight after creating it and type into the popup.
Text (T icon)	Click anywhere on the page to drop a text box. Type your note. Move or resize as needed. Pick font size and color from the inline controls. Empty text boxes are not saved — type something or it's discarded.

Each annotation is autosaved within a second of you finishing the edit — no Save button to remember. A small toast appears if a save fails (typically a transient network issue; the next edit retries).

Comments are attached to highlights, not created with a separate tool. Make a highlight, click it, write the comment.

What's not available in v1: image stamps and signatures. Print and download are disabled in the subscription reader by design.

Personal vs. team subscriptions

The Workplace adapts to the kind of subscription you're using.

Personal subscription

If your subscription belongs to your personal account, you're the only person who has access to it. Annotations you create are private by definition — there's no "share" concept because nobody else can open the same subscription anyway.

In this mode:

The side panel shows only your own annotations.
Every annotation is marked Private with a lock icon.

Team / business subscription

If your subscription belongs to your organization's business account, everyone in that organization who has access to the same subscription can see annotations that you've published. By default new annotations stay Private — visible only to you — until you flip them to Shared.

In this mode:

The side panel lists your private annotations plus every annotation your colleagues have published on this standard. Shared annotations are always visible — there is no per-user opt-out for the shared layer.
Each of your annotations has a small lock/people icon you can click to switch between Private and Shared.
Annotations from colleagues display their author name and a people icon indicating they're shared.

Publishing an annotation

In the side panel, find the annotation under its page group and click the lock icon next to it. It flips to a people icon — your colleagues will see it within about 15 seconds on their next refresh cycle, or immediately the next time they open the document. Click the same icon again to unpublish; colleagues stop seeing it on their next refresh.

Only the original author can publish, unpublish, or delete an annotation. Other colleagues can read shared annotations but cannot modify them.

Deleting an annotation

Each of your own annotations has a trash icon in the side panel — click it to remove the annotation from both the document and your team's view. Deletion is immediate and permanent; there is no undo or restore.

How your colleagues see your work

The side panel polls for changes about every 15 seconds. When you publish an annotation, your colleagues will see it appear on their canvas — on the right page, in the right place — within that window.

If a colleague is actively reading the same document at the same time, they won't see your edits in flight, only after each polling tick. The Workplace is designed for collaborative review, not real-time co-drawing.

Deletions are slightly different: a deleted shared annotation doesn't disappear from a colleague's screen until they close and reopen the document. This keeps the live polling lightweight. If you need an immediate retraction, ask the colleague to reload.

The side panel

The right-hand panel is your map of every annotation on this document.

Annotations are grouped by page so you can scan what's on each page at a glance.
Each row shows the author name, an icon for the annotation type (pen / highlighter / text), and — for your own rows — small Private/Shared and Delete icon buttons on the right.
Click any row to navigate to that annotation: the viewer scrolls to its page (just the viewer, your page header stays in place) and the annotation pulses with a brief outline so it's easy to spot.
The empty state appears the first time you open a document with no annotations yet.
A Show annotations toggle at the top of the panel hides every annotation from the PDF and dims/disables the panel rows. Flip it back on to make them all reappear instantly. Useful when you want a clean read of the underlying standard without leaving the workplace.
The whole panel is collapsible: click the small − in the top-right to slide it off-screen. A vertical Engineering Workplace tab appears against the right edge of the page; click it to slide the panel back in. On phone-sized viewports the panel starts collapsed by default — open it with the tab.

What happens to your annotations over time

Situation	What happens
You close the browser tab	Everything is saved already. Reopening the document restores all your annotations at the exact same positions and zoom levels.
Your subscription expires	You lose access to the document, but your annotations are kept in our database. If the subscription is renewed (or you re-join the organization that owns it), they reappear.
You leave the organization	Your published shared annotations remain visible to the team. Your private annotations stay attached to your account and reappear if you rejoin.
A colleague leaves the organization	Their previously-published shared annotations remain visible to the team. Their private annotations were never visible to anyone else and remain inaccessible.

The platform does not silently purge annotations on expiry. This is deliberate: lost annotation work would be a much worse user experience than a stale row in the database.

Tips

Highlights stick to text, drawings stick to pages. A highlight you make follows the underlying text characters — even if the document is reflowed in your browser, the highlight stays on the right phrase. Freehand drawings and text boxes are pinned to absolute page coordinates and don't track text.
Use draw for big-picture markup, text for precise notes. A circle around a clause communicates intent quickly; a text box with two sentences explains why.
Drawings save automatically after a brief pause. When you stop drawing for about a second, the stroke commits and saves. To draw a multi-stroke shape (e.g., several arrows in one annotation), keep drawing without long pauses. To start a new annotation, pause briefly between drawings.
Use the panel rows to jump around. On a long standard, the side panel doubles as a navigator — click any annotation to scroll the viewer to its exact spot.
Publish liberally during reviews, prune later. You can always unpublish. There's no notification spam tied to publishing, so your team won't get pinged for every change.
Polling is intentionally slow (~15 s). This keeps the platform responsive and bandwidth-light. If a colleague's edit doesn't show up in your panel right away, give it a few seconds and refresh.
Annotations are isolated per subscription. If your organization has two subscriptions that both grant access to the same standard, annotations made under subscription A are not visible under subscription B. This is by design — each subscription has its own workspace.

Frequently asked

Will my annotations affect the original PDF? No. The PDF you see in the viewer is always the unmodified standard. Annotations are stored separately and overlaid on top of the viewer at runtime.

Can I print or export a copy of the standard with my annotations? No. Print, download, and "save as" are intentionally disabled in the subscription reader to protect standards licensing terms. Annotations exist for review and collaboration, not for redistribution.

Can I search the text of my notes? Not in v1. The annotation payload is stored as structured data and isn't indexed for full-text search yet. Searching across notes is on the roadmap.

What browsers are supported? Any modern Chromium-based browser (Chrome, Edge, Brave), Firefox, and Safari. The annotation tools rely on the same PDF.js engine used by every modern browser's built-in PDF viewer, so behavior is consistent across them.

Does it work on mobile or tablet? The viewer renders on tablets and large phones, but the annotation toolbar is laid out for a desktop workflow. We recommend a desktop or laptop for serious annotation sessions. On phone-sized viewports the side panel starts collapsed by default — use the vertical Engineering Workplace tab on the right edge to slide it in when you need it. The panel needs roughly 280 pixels of horizontal space.

My colleague published an annotation but I don't see it. Wait 15-30 seconds and the side panel will refresh. If it still doesn't appear, confirm you're both opening the same document under the same subscription, then reload the page once.

An annotation disappeared after I refreshed. This usually means a save failed silently. If you can reproduce it, please open a support ticket with the document name and the rough time of the missing edit — server logs can show whether the save reached us.

Known limitations in v1

No image stamps or signatures. The toolbar buttons for these are disabled.
No standalone "Comment" tool. Comments attach to highlights — make a highlight, then click it to add a comment. The standalone comment-toolbar button is intentionally hidden because it required a target and was confusing on its own.
Deletes propagate on reload only. When a colleague deletes a shared annotation, it disappears from your view the next time you open the document, not in your live session.
Single organization per user. If you belong to multiple organizations, the Workplace uses the subscription you opened the document through to determine the sharing scope. There's no multi-org chooser in v1.
No annotation history. Edits and deletes are not versioned. You can't "undo" a publish or restore a deleted annotation.
Drawings auto-commit after ~1 second of idle. If you pause mid-sketch, the in-progress stroke is committed as its own annotation. Keep drawing without pause to combine strokes into one annotation.

Future versions will lift several of these — let us know which limitations matter most for your team's review workflow.
