PDF Reviews Are Broken in Engineering
Current workflows create delays, miscommunication, and frustrated teams.
Email Chain Hell
Markups get lost in email threads. Version control becomes impossible. Critical feedback falls through the cracks.
Desktop-Only Tools
Field teams can't mark up drawings on tablets. Site visits require printed plans. Mobile reviews are impossible.
Expensive Licensing
$300+/user/year for BlueBeam, even for reviewers who barely use it. Budget-breaking for large project teams.

Case Study: Oil & Gas Engineering Firm
How Goldline streamlined reviews for a new diesel processing unit
The Challenge
A growing oil & gas engineering firm was juggling 200+ technical documents for a complex new diesel processing unit. Traditional email chains and static PDFs created bottlenecks, with engineers spending hours coordinating markup reviews across P&IDs, equipment drawings, and process flow diagrams.
The Solution
Deployed Goldline across their 9-person engineering team. Now technical drawings get real-time collaborative markup, with instant notifications keeping everyone aligned on design changes and approval status.
"Goldline has been a game-changer for our diesel processing unit project. We've eliminated the chaos of email markup chains and now our team can actually collaborate in real-time on complex P&IDs and process diagrams. The time savings alone paid for itself in the first month."
