Convert 3D files
Select the 3D CAD files you want to convert:
To create a single-page document, choose File > Create PDF > From File. Select the 3D file, and clik Open.
To create a multipage document in which each 3D file is on a separate page, choose File > Create PDF > From Multiple Files. Clik the Add Files button to select the 3D files, clik Next, review the files, and then clik Create.
In the Acrobat 3D Conversión dialog box, select the preset or individual settings you want to use, and clik OK.
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-clik 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).
