fig. 01 · features

Purpose-built for the drawings you keep for decades.

Lunr puts every drawing under revision control, makes the text inside a scanned drawing searchable, opens CAD and BIM in the browser, and finds documents by where they sit on a map. Here is what each part of the platform does.

fig. 02 · document control

Every revision under control, from delivery through operation.

Classify documents by folder, tag, and portfolio, then keep every revision numbered, approved, and audited. The controlled version is never in doubt, from the first draft to the as-constructed set.

Controlled documents with approvals and a full audit history.
Automated document and version numbering, applied on upload.
Revision control, so the superseded copy is never mistaken for the current one.

numbered automatically on upload · version incremented on each revision

Every controlled document is numbered on upload, so REV C is always REV C and never the file someone renamed.

Classify by folder for hierarchical browsing.
Tag documents for grouping, reporting, and search.
Set tag-based permissions, for example every electrical document on the Melbourne campus.
Group the repository into portfolios for targeted search.

Compare two revisions.

Lay one revision over another and see exactly what changed. Compare side by side or as an overlay, on drawings and PDFs, so a review reads the difference between REV B and REV C at a glance.

Overlay one revision on another, with every change picked out.

Print a sheet that links back to the record.

Print a drawing with a QR code in its title block. Scan it on site, and Lunr opens the live controlled document, so you always know the sheet in your hand matches the current revision.

fig. 03 · projects and collaboration

Bring the whole project in. Keep the record clean.

Run project spaces with the approvals your process requires, and take handover that arrives complete. Lunr is a common data environment (CDE) when your projects require one.

Project spaces that gather the right documents and the right people.
Document workflow with the approvals and sign-offs your process requires.
Handover that runs through Lunr, so the as-constructed set arrives complete.
Notifications keep reviewers and approvers informed at each step.

Users and Collaborators.

Your own team are Users. Contractors and consultants join as Collaborators through transmittals, RFIs, and project spaces, and see only the documents you grant them by tag.

fig. 04 · XRAY search

// the differentiator

Search the text inside the drawing.

XRAY runs OCR and AI across everything you store, so a valve tag from a 1994 scan turns up as fast as a file you saved this morning. Incumbent search reads the filename. XRAY reads the drawing.

full-text OCR and AI · DWG · DGN · RVT · PDF · Office · scanned images · deep xray tiled re-scan · advanced search · wildcard and boolean · tag filters

go deeper /XRAY

XRAY search results in Lunr shown as rendered thumbnails, including a cost plan spreadsheet, a design report, a point cloud scan, and a building model.

Full-text search across file names, titles, tags, and document content.
Deep XRAY re-reads a dense drawing in high-resolution tiles, from 2×2 up to 4×4, so faint or crowded text still resolves.
Configure advanced search around the tags and metadata that matter to your data.
Run wildcard and boolean queries, then narrow with tag filters.

Lunr's Advanced Search panel with a keyword, a discipline filter, file-name filters, and options including Include XRAY and Exact match.

Review a drawing together in real time. Everyone in the drawing has a cursor in their own colour, so you see who is looking, where they are pointing, and the comments they leave as they leave them.

Take a measurement off the model.

Foundry measures on the geometry itself. Pick two points for a length, a face for its area, or a solid for its volume, and read the figure straight off the model.

fig. 06 · maps and GIS

Find documents by where they are.

Geo-tag documents and plot them on a live map. Draw a boundary to pull back everything inside it, or browse from where you stand on site.

See every geo-tagged document on the map, clustered by location.
Load asset data from your GIS as map layers for search context.
Toggle a streets or aerial basemap.

Lunr's map view centred on Sydney Harbour, with a cluster of documents, single document points, and the filters and layers panels.

Draw a polygon around an area, and Lunr returns every document inside it.
Geo-tag a document from your current location on site.
Bring in Esri GeoJSON layers to enrich the map with your own asset data.
