Browser-based annotations and feedback on CAD models for remote reviews
Remote workers in manufacturing struggle with clunky CAD collaboration tools that fail to sync reliably across distributed teams.
Upload CAD files to DesignAnnotate for instant 3D browser viewing and collaborative annotations without needing CAD software installed. Teams leave precise pin-point comments, measure changes, and track feedback loops in real-time. Perfect for async reviews in distributed manufacturing.
