The engineering record for a plant, and every modification since.
A manufacturing plant holds mechanical and electrical drawings, P&IDs, and layouts for equipment installed across decades, changed at every shutdown, and documented by OEMs in whatever format they send. Lunr puts that record under revision control in one register, makes the text inside a scanned vendor drawing searchable, and puts the current revision in the hand of the person standing at the machine.

Every drawing on the plant in one controlled register.
Mechanical drawings sit with one discipline, electrical schematics with another, and the P&IDs and layouts with whoever drew them last. Group each plant, line, and area into a Portfolio, keep every drawing under revision control, and a superseded sheet is never mistaken for the current one.
- Hold mechanical, electrical, P&ID, and layout drawings for every line and area under revision control.
- Group plants, lines, and areas into Portfolios, each carrying its own asset information.
- Automatic document and version numbering, applied in your register format as records are booked in.
- Classify by folder and tag, and set tag-based permissions, for example every electrical drawing on one line.
- Export all metadata, drawings, and models at any time, so the record stays with the plant.

See what changed, revision by revision.
Equipment gets modified at every shutdown, and a drawing set drifts from the plant as it stands until nobody trusts it. Keep each change as a numbered revision with a full history behind it, and lay one revision over another to read exactly what moved.
- A full revision history on every drawing, so each modification can be traced and evidenced.
- Lay one revision over another and see every change picked out, side by side or as an overlay.
- Mark up the drawing in the viewer, and turn the redline straight into a change request or an RFI.
- Change requests that hold, forward, and close on an audit log that writes itself.

The current revision, at the machine.
The drawing office holds the record, and the work happens on the floor, often in a plant room with no reception. Print a sheet with a QR code in its title block, and a scan on the phone opens the live controlled document, so maintenance and production staff know whether the print in their hand is still current.
- Print a drawing with a QR code in its title block, and scan it on site to open the controlled document.
- View DWG, DGN, RVT, and PDF in the browser, with no CAD licence and nothing to install.
- Download a collection of documents before a shutdown, and read it where there is no reception.
- Submit a redline request, comment, attach a photo, and move a document through its workflow from the app.

Search inside the vendor set, whatever format it arrived in.
Equipment suppliers send what they send: a scanned manual, a PDF general arrangement, a DWG from a machine builder, a spreadsheet of spares. XRAY runs OCR and full-text search across all of it, so an equipment tag or a part number printed inside a vendor sheet is findable years after the purchase order closed.
- OCR and AI full-text search across every DWG, DGN, RVT, PDF, Office file, and scanned image.
- Find an equipment tag, a line number, or a part number printed inside the sheet, not just the file name.
- Deep XRAY re-scans a dense P&ID or general arrangement tile by tile, so nothing on the drawing is missed.
- Filter results by metadata, tags, and revision to narrow a large plant archive fast.

Handover that arrives complete on every equipment project.
A new line, a capital upgrade, and a single machine purchase all end the same way: a package of drawings, manuals, and certificates from a contractor or an OEM. Validate each package against a manifest, and exchange sheets with vendors on a tracked transmittal, so the missing as-constructed drawing is caught on upload rather than found during the next shutdown.
- Validate each handover package against a manifest, and read title-block tags into metadata.
- Issue tracked transmittals for vendor exchanges, through sent, received, and acknowledged.
- Move deliverables through configurable review and approval workflows.
- Contractors, OEMs, and integrators deliver as Collaborators, and see only what you grant them.

Trusted with records owners keep for decades.
A plant keeps its drawings for the operating life of the equipment. The University of Canberra keeps its estate record the same way: it moved the archive off SharePoint and put it under control.

How the record is held today, how the floor gets the current revision, what happens to a modification, and where the data sits.
- How do manufacturers manage plant and equipment drawings today, and how is Lunr different?
- Most plants keep drawings in nested folders on SharePoint or a shared drive, split across the drawing office, maintenance, the disciplines, and whichever OEM supplied the equipment. The current revision is a guess, superseded sheets stay in circulation, the text inside a scanned vendor drawing is invisible to search, and there is no audit trail. Lunr puts every drawing under revision control in one register, keeps the superseded copy marked, searches the words printed inside each sheet, and logs every change. The University of Canberra moved more than 20,000 documents off SharePoint onto Lunr for this reason.
- How does a fitter at the machine know the sheet in their hand is current?
- Print the drawing with a QR code in its title block. A scan on the phone opens the live controlled document, so the sheet in your hand is checked against the current revision before anyone works to it. The Lunr app for iPhone and Android reads the same repository your team works in, and a collection of documents can be downloaded before a shutdown so it stays readable in a plant room with no reception.
- Can maintenance and production staff view a P&ID without a CAD licence?
- Yes. Anyone with access opens DWG, DGN, and PDF drawings in the browser through the Rift viewer, with layers, measurement, and markup, and nothing to install. Models open in Foundry and point clouds in Nimbus. A CAD seat is only needed to author drawings, so maintenance, production, and engineering staff read a P&ID or a general arrangement without one.
- Can Lunr search inside scanned OEM and vendor drawings?
- Yes. XRAY runs OCR and full-text search across every drawing, scans included, so an equipment tag, a line number, or a part number printed inside a vendor sheet is findable whether the file was saved this morning or scanned from a decades-old equipment file. Deep XRAY re-scans a dense P&ID or general arrangement tile by tile, so nothing on the drawing is missed, and results filter by metadata, tags, and revision.
- How does a modification made on the floor get back into the drawing?
- Whoever is standing at the machine marks up the drawing in the viewer and turns the redline straight into a change request or an RFI, so the question and the sheet that raised it stay together. The change request holds, forwards, and closes on an audit log that writes itself, and the approved revision lands in the register with a full history behind it. Revision compare lays one revision over another, so a review reads the difference between REV B and REV C at a glance.
- How does handover work on a capital project or an equipment purchase?
- Validate each handover package against a manifest, so a missing as-constructed drawing is caught on upload rather than found during the next shutdown. Lunr reads title-block tags from every sheet into metadata, applies your register numbering as records come in, and issues tracked transmittals through sent, received, and acknowledged. Contractors, OEMs, and integrators deliver as Collaborators, and see only what you grant them.
- Where is our data hosted, and does Lunr work alongside our maintenance system?
- Lunr is hosted in Australia and the US, and your instance sits in the region you require, so plant records stay onshore. Staff sign in over SAML with your identity provider, and every controlled document carries a full audit trail. Lunr holds the engineering record while your EAM runs maintenance, and an export connector for IBM Maximo keeps the two in step, so a work order runs against the current drawing rather than a superseded one. Over 10 million documents are under management on Lunr today.
