415 ADOBE ACROBAT 3D VERSION 8
User Guide
If a 3D model’s geometry was saved to PDF (using a PRC B-rep conversion setting), you can export and use it in CAM
and CAE applications. Geometry is translated directly to standard file formats that comply with published specifica­
tions: IGES, ParaSolid, STEP, and VRML. Product Manufacturing Information (PMI) isn’t included in the file.
You can modify the exported data by specifying settings. In some situations, Acrobat 3D may modify the exported
data to improve the results, while avoiding any changes to the actual geometry. For example, if the source CAD appli­
cation is loose-tolerant and the export format is tight-tolerant, Acrobat 3D may add a tolerance to the exported file.
1 Open the 3D PDF and click the 3D model in the document pane.
2 Right-click the 3D model and choose Export Data.
Note: The Export Data option isn’t available if compression or security was applied to the 3D PDF, or if the tolerance
was set to 0.01 or higher during PDF conversion.
3 Choose a file format from the Save As Type menu, click Settings to select the options for that format, and click OK.
4 Name and save the file.

Format options
Specify the following options for exported geometry by clicking the Settings button in the Save As dialog box.
IGES Settings
IGES files are saved as version 5.1 and support solid entities.
Save Solid To Specifies how to write the geometry. The Surface option provides UV curves and any 3D curves (if
present). The Solid option provides UV curves (if present) but calculates 3D curves.
Save Faceted To Specifies whether to write polyhedric solids as trimmed surfaces (Faceted) or as lines (Wireframe).
Save Analytics To Writes surfaces (cylinders, planes, spheres, cones, torus) and curves (circles, ellipses, parabolas,
hyperbolas) as analytic shapes instead of NURBS (Non-Uniform Rational B-Spline).
Write Hidden Objects Specifies that blanked entities in the file will be included.
ParaSolid Settings
Files are saved as version 11. Specifies whether to save geometry as solids or surfaces.
STEP Settings
STEP Standard Specifies the Application Protocol (AP) that best suits the intended use (AP 203 or AP 214).
Save Faceted To Specifies whether to write polyhedric solids as trimmed surfaces (Faceted) or as lines (Wireframe).
Save Analytics To Writes surfaces (cylinders, planes, spheres, cones, torus) and curves (circles, ellipses, parabolas,
hyperbolas) as analytic shapes instead of NURBS (Non-Uniform Rational B-Spline).
Use Short Names Uses internal coding for STEP entities and reduces file size.
VRML Settings
Specifies the version, either 1.0 or 2.0.
