LAMBDA PDF S&E combines professional PDF tools, CAD-style drawing, engineering measurement, OCR, forms, and collaboration in one focused Windows desktop application.
Developed by Eigenexis Systems
Core product capabilities
Review, edit, draw, measure, search, complete, and coordinate engineering documents without moving between disconnected applications.
Open, organize, mark up, compare, edit, secure, and deliver professional PDF documents.
Technical PDF editing for engineersCreate and modify precise engineering geometry directly on the PDF.
CAD-style drawing inside PDFCalibrate drawings, measure geometry, perform takeoff, and organize quantities.
PDF measurement and drawing calibrationMake scanned drawings and reports searchable, indexed, and easier to navigate.
OCR for scanned engineering drawingsCreate, complete, validate, calculate, flatten, and preserve structured PDF forms.
Structured PDF forms for technical workCoordinate comments, issues, revisions, permissions, and technical review history.
Engineering PDF collaboration and reviewProfessional PDF
Prepare, review, revise, compare, secure, and issue technical PDF documents from one professional workspace.
Combine documents, arrange pages, manage bookmarks and links, and prepare structured drawing packages.
Use markups, callouts, clouds, shapes, stamps, layers, statuses, replies, and reusable tools.
Inspect revisions, align drawing issues, identify changes, and perform supported document and content edits.
Apply permissions, passwords, redaction, signatures, certificates, flattening, and controlled document output.
CAD & measurement
Draw, constrain, inspect, and measure technical geometry while keeping the document, scale, and review context visible.
Construct and modify technical geometry directly on drawings, layouts, diagrams, and specifications.
CAD-style drawing inside PDFTurn drawing geometry into traceable measurements and quantities connected to the relevant scale and document context.
PDF measurement and drawing calibrationMove from reviewing a drawing to constructing, validating, and documenting engineering intent in the same workspace.
Built for engineering, construction, manufacturing, inspection, estimating, and technical project delivery.
OCR, forms & collaboration
Recover searchable text from scanned drawings, reports, and specifications, then locate tags, notes, references, and technical details.
OCR for scanned engineering drawingsCreate and complete structured records for inspections, approvals, field reports, equipment data, and project turnover.
Engineering PDF form workflowsKeep comments, issues, revisions, assignments, and review decisions connected to the document and project.
Document-centred technical reviewEngineering workflow
Open the document, locate the relevant information, add or inspect engineering geometry, measure the drawing, coordinate the review, and preserve the result.
PDF operations, geometry, measurement, and rendering are governed by the underlying engineering engine.
The first release is designed as a focused Windows x64 desktop application for technical document work.

FAQ
LAMBDA PDF S&E is a focused Windows desktop application for professional PDF work, CAD-style drawing, engineering measurement, OCR and search, PDF forms, and document-centered collaboration. It is designed for technical teams that need precise work without repeatedly moving between disconnected applications.
No. It brings useful CAD-style geometry, snapping, constraints, dimensions, and editing into the PDF workflow. The goal is to support drawing review, measurement, takeoff, technical communication, and small geometry changes while the source document and engineering context remain visible.
The first public beta is planned for Windows x64 desktop systems. Qualified operating-system versions, graphics requirements, memory guidance, and installation details will be confirmed as release testing progresses.
OCR and document-wide search are part of the planned Windows release. The application is intended to recognize text in scanned drawings, reports, and specifications, then show highlighted results in their original page context. Recognition quality will depend on the source document.
Collaboration is included in the planned release scope, with projects, comments, issues, ownership, review status, permissions, and history kept close to the document. Individual capabilities remain subject to final integration, persistence, security, and release qualification.
The Windows public beta is planned for December 2026. Timing remains subject to integration, persistence, rendering, performance, security, packaging, and release qualification. Join early access to receive milestone updates and confirmed availability information.
