3 Click the Settings button, click the OpenGL tab, and set the capture units to match the 3D model. Edit other 3D
capture settings as necessary, and then click OK.
4 Click the window containing the 3D model to make it active, and then press the Print Screen key.
5 Switch to Acrobat Pro Extended, edit the capture settings in the Conversion dialog box as needed, and then click OK.
After the initial capture with a CAD application, you can simply start Acrobat Pro Extended, open the 3D file in the
CAD application, and press the Print Screen key to capture.
3D capture settings
You can change capture settings when capturing a 3D model from a CAD application or when editing capture settings
in the Preferences dialog box.
The General tab lets you adjust the geometry settings of captured 3D models.
The OpenGL tab lets you adjust the settings for unknown or untested 3D applications. OpenGL is a cross-language
platform for creating 3D models. Applications can use OpenGL in different ways. Acrobat recognizes how most
applications use OpenGL, but for unknown applications, the OpenGL tab lets you change settings to improve the
capture.
General tab for capture settings
Discard Stray Points And Lines Deletes any orphaned lines and vertexes that cannot be meaningfully incorporated into
the 3D model. Removes boxes around notations used for geometric dimensioning and tolerancing (GD&T). This
option removes points and lines from the 3D model itself. For example, in Revit models, wall textures are drawn using
lines and points above the polygons.
Discard Textures Removes all textures from the materials in the captured model. Selecting this option can greatly
reduce the file size.
Group Geometry By Material Combines mesh pieces that have the same color and material.
Discard Surface Normals Recomputes the normal data based on the angle between adjacent faces. Surface normals are
used for constructing smooth surfaces. Selecting this option reduces the file size and can change the appearance of the
3D model.
Toggle Y And Z Axis Allows conversion between y-up and z-up coordinate frames if the native coordinate systems for
the model are represented differently than in Acrobat.
OpenGL tab
Frame Buffer Mode Indicates which OpenGL event—Toggle On Swap, Toggle On Clear, or Toggle On Flush—triggers
the beginning and end of a capture frame. If a capture yields undesired results, try different buffer modes to see if the
capture quality improves.
View Transform Mode Specifies the transformation (First Matrix, Last Matrix, or No Matrix) to represent the camera
transform. Use this option if the measurements in Acrobat are incorrect or if the top, left, and front views in Acrobat
don’t match these views in the CAD application.
Capture Units Specifies the units of measure to be used when using the Distance tool to measure the 3D model.
