Working with PDF documents on computers and mobile devices is one of the standard solutions for exchanging electronic documents around the world. The free Acrobat Reader offers more options than other programs for reading, printing, and reviewing PDF files. Now, to show the customer your project in 3D, it is enough to send him a file in 3D PDF format. This option of workflow with third-party partners excludes the transfer of the project in the native Renga format (RNP), therefore, the issue of intellectual property is resolved – all the author’s achievements will remain with him.
