From the desktop, you can drag a 3D file into Acrobat 3D (or onto the application icon) to create a new single-page
PDF file. Or, you can right-click the 3D file and choose Convert To Adobe PDF (for a single file), Convert To Adobe
PDF And Email, or Combine Supported Files In Acrobat (for the selected file plus additional files that you select in the
dialog box that appears).
Convert a 3D file using PRC settings
Use PRC settings to create a PDF that contains Product Manufacturing Information (PMI), polygon settings or
tessellation, and geometry or b-rep (boundary representation). After you create the PDF, you can export geometry to
standard file formats that most CAM applications read.
Choose File > Create PDF > From File, select the 3D CAD file, and click Open.

In the Acrobat 3D Conversion dialog box, click the Import tab.
To import Product Manufacturing Information (PMI) with the 3D model, select 3D PMI (Text, Notes, GD&T).

You can import PMI from CATIA V5, I-DEAS, JT, NX (Unigraphics), and Pro/ENGINEER files.

To replace the fonts used in PMI, click Fonts, select Always Substitute, specify the font, and click OK.
If you select Always Substitute, you remove any reference in the PDF to the font used for PMI. If you leave Always
Substitute unselected, Acrobat 3D substitutes any missing fonts; if the original fonts become available, they are used
to display PMI.
Choose a PRC setting from the Format menu:

(Optional) To apply compression, click the Optimize tab, and select a PRC compression option. If you plan to

export geometry, leave Compress B-rep unselected, or set the value to 0.001 millimeter.
Compressed PDFs are smaller but take longer to open than uncompressed PDFs. To save time, compress only when
you have to—after PDF conversion: Right-click the 3D model, and choose Optimize PDF. This option is available
only in PDFs that were converted using PRC settings.
Note: When you secure a 3D PDF that contains geometry, avoid settings that restrict editing and printing the PDF—
unless you want to disable the option to export geometry.
Convert a 3D file using U3D settings
