What is a Drawing Management System, and How Do You Choose One?
A drawing management system holds engineering drawings under revision control, with the CAD handling and controlled issue generic document management leaves out. What it does, and how to choose one.
article
How will the CDE Evolve?
The Common Data Environment (CDE) is poised to reshape the roles of the Client, Asset Owner, and Occupier. Increasing volume and diversity of data in projects signals a promising evolution.

AutoCAD Attributes: Block Attributes, ATTDEF, and Title Block Data
What a block attribute is in AutoCAD, how to define one with ATTDEF, how to edit one with ATTEDIT and BATTMAN, and why title block attributes matter to a drawing management system.
article
Construction Document Communication
A look at communication methods used during the project and maintenance phases of an asset, and how Lunr allows you to tame this process and get your communications back under control.
article
Drawing Revision Numbering: Letters, Numbers, and Rev 0 vs Rev 1
How drawing revision numbering works in practice: which letters the convention skips, what the first revision should be, when a drawing moves to rev 0 or rev 1, and where superseded revisions go.
article
Engineering Drawing OCR: Scanning and Searching Legacy Drawings
How OCR reads the text printed on an engineering drawing, what it pulls out of a title block, and how scanning a paper archive turns decades of drawings into something you can search.

Tackling Engineering Project Costs with Submittal Package Validation
Package validation in Lunr reduces the feedback loop from drawing handover to acceptance and increases the likelihood that the original draftsperson is still on hand to make the required corrections.
article
Understanding Controlled Documents
Lunr provides a way to manage controlled documents through the complete document lifecycle, while still allowing you the option of uploading uncontrolled documents as required.
article
Understanding Document Workflow
Lunr's document workflow allows controlled collaboration between all members of the project team, including staff, vendors, sub-contractors, and more.
article
Understanding Transmittals
Document Transmittals are a formal process used by Engineering and Construction companies to send controlled documents or drawings to external companies, contractors, or vendors.
article
What is a Redline Drawing, and How Do Redline Markups Work?
A redline drawing is a released sheet marked up in red to show what should change. What redline markups record, who drafts the change, and how construction redlines become the as-constructed record.
