How does measurement calibration work in the Unified Viewer, and which tools support it?
Answer
Measurement calibration in the Unified Viewer allows users to set custom scales on web for PDF files across the Document Management, Drawings(Beta), Documents, and Specifications tools. If a document lacks a scale bar or legend, select any measurement tool, click Calibrate in the Scale modal, drag your cursor across a known distance on the document, and enter its real-world measurement value. You can also choose from preset scales and adjust precision levels before creating measurement markups.
