Built for the way construction actually works.
Lode Draw is the first module. It compiles your drawing set, tracks every revision, and gives the team a place to comment, measure, and resolve what changed — without touching your source files.

Automatic Sheet Detection
Upload a PDF drawing set and Lode identifies every sheet — by page label, bookmark, filename, or OCR of the title block. Sheet numbers are parsed into discipline, series, sequence, and suffix. Sorted automatically in AIA standard order.
Revision Resolution
When a new issuance arrives, Lode compares it against the existing registry and resolves the current authoritative version of every sheet. Latest revision wins — but nothing is ever deleted. Full history preserved.
Replace + Amend Sets
Every revision event generates two compiled PDFs. The Replace Set contains only current sheets — clean, field-ready. The Amend Set includes superseded sheets with a clear overlay — the full project record in a single document.
Sheet Index + Revision Log
A structured sheet index showing every current sheet, its source issuance, and its reference health. A chronological revision log showing every issuance processed and what it changed. Both generated automatically on every upload.
Reference Integrity Tracking
Lode tracks existing sheet-level references across the compiled set. When a revision causes a reference to break, it's flagged immediately. A dedicated review dialog lets you re-link, acknowledge, or defer — every decision logged.
Doc — AI Revision Summaries
Enable Doc on any project and get a plain-language summary of every revision issuance. What changed, what's new, what to pay attention to. Optional, clearly labeled, and never trained on your drawings.
Sorted the way you expect.
Lode uses AIA standard discipline order — G, C, L, S, A, I, P, M, E — so your sheet index always reads like a real drawing set. Suffix sheets (A201A, A201B) insert correctly between their parent sheets.
You'll never see A301 sorted after Z101.
Markup & Review
The drawing is just the starting point.
Once a set is compiled, your team needs to talk about it, measure off it, and resolve what changed. Lode keeps every comment, count, and decision attached to the right sheet — and to the right revision.
Comments in context
Pin questions or notes directly on a sheet. Threaded responses, open/resolved status, internal-only by default. Every comment lives with the drawing it references.
Highlights and callouts
Mark areas of interest with semi-transparent highlights. Flag scope changes, callouts, or anything the team needs to look at — without ever modifying the source PDF.
Calibrated measurements
Linear and area measurements with per-zone scale calibration. Architectural and civil presets included. Numbers stay accurate across revisions.
Count tool
Tally fixtures, doors, devices — anything you need to count off a drawing. Grouped, filterable, exportable.
Reference review workflow
When a revision breaks an existing sheet reference, Lode flags it. A dedicated review dialog lets you re-link, acknowledge, or defer — every decision logged with a timestamp.
Non-destructive overlay
All markup lives on an SVG layer over the PDF, never baked into your drawings. Toggle visibility per item. Export with or without markup.
Every markup, tied to a revision.
Comments, measurements, and reference flags all live on a non-destructive overlay above the PDF. Each item is owned by the person who placed it, timestamped, and linked to the issuance the sheet came from.
When the sheet is superseded, the markup history travels with it.
Coming Next
Specs, on the same engine.
The same revision compiler that resolves your drawings will resolve your specifications. Upload addenda as they arrive. Lode parses CSI section numbers, identifies the current authoritative version of every section, and flags drawing-to-spec conflicts before they reach the field.
- Per-section revision history
- CSI MasterFormat parsing
- Drawing ↔ spec cross-reference checks
- Plain-language coverage summaries
After Specs: Lode Diff · Lode Rev · Lode Dex. The same pattern, applied to every document type on a project.

We'll be in touch when early access opens.
