Engineering document format using PDF — Part 1: Use of PDF 1.6 (PDF/E-1)

This standard defines a file format for the exchange of engineering documents based on the PDF 1.6 format.

PDF/E improves document exchange, collaboration, and print accuracy within engineering workflows, both inside companies and with extended enterprises of partners, suppliers, customers, government organizations and citizens. It enables organizations to streamline engineering workflows that incorporate diverse sets of complex documents, resulting in improved productivity and the ability to more quickly deliver better products to market. It defines the features of PDF that are required, recommended, restricted, or prohibited when creating viewing, marking up, printing, analyzing, and distributing engineering documents.

PDF/E takes into consideration the differing needs of both interactive and non-interactive readers. It specifies the proper use of PDF for on-screen display and printing of engineering documents.

In 2020, PDF/A-4 (ISO 19005-4:2020) was published which directly supports PDF 2.0-based engineering documents via a specialized long-term preservation conformance level known as “PDF/A-4e”. PDF/A-4e supports 3D PDF using RichMedia (U3D and PRC) with 3D annotations and JavaScript.
