3D conversion settings
You can change how the 3D model imports by changing the options on the various panels
in the 3D Conversion Settings dialog box. These settings appear when you import a 3D
CAD file or when you choose Edit > Preferences > Convert To PDF.
General settings
The settings on the General panel determine how Acrobat presents the 3D model when
imported. Unlike the settings on other panels, the General panel settings do not affect the
imported file itself.
Default Background Color
Specifies the background color that appears behind the 3D model. You can change the
background color at any time by using the Background Color pop-up menu on the 3D
toolbar.
Default Lighting
Determines the default lighting style, such as None, Daylight, or Blue. You can change
the lighting at any time by using the Lighting pop-up menu on the 3D toolbar.
Default Rendering Style
Determines the default render appearance, such as Wired or Solid Outline. You can
change the rendering style at any time by choosing an option from the Model Render
Mode pop-up menu on the 3D toolbar.
Default Animation Style
Determines whether the animation in the imported 3D model is turned off, loops
(repeatedly replays from the beginning), or bounces (plays forward, then backward, and so
on). The 3D model must include animation for these options to take effect.
Add Default Views
Adds views to the Views menu on the 3D toolbar. To add default views, select this option,
and choose a view style. An orthographic projection effectively removes a dimension,
preserving the size ratio between objects but giving the 3D model a less realistic
appearance. The orthographic projection's view is especially useful for viewing certain
diagrams, such as 3D mathematical functions plotted on a graph. A perspective projection
offers a more realistic scene in which objects in the distance appear smaller than objects of
the same size in the foreground. Isometric projection uses the same 120° angle of
projection for the x, y, and z axes.
Default Script
Attaches a JavaScript file, which runs when the 3D model is activated. If the 3D model
you're importing does not include embedded JavaScript, you can click Browse and specify
a JavaScript file to run when the 3D model is enabled. (See
Preview Image
Determines what appears in the 3D model area when the 3D model is not activated. You
can leave the preview area blank, use the default view of the 3D model, or select a
different image to use as the preview for the 3D model.
Import settings
The Import panel includes 3D CAD import-specific settings that are available for the
formats supported by Acrobat 3D. The Import panel is blank for many file types,
including 3DS files. When conversion of the 3D model occurs, a representation of the
model is generated, often causing deviation from the original file. Adjust settings in the
Import panel to try to improve the representation of the 3D model.
The Import panel may include the following options:
Surface Tolerance
Indicates how many units the surface can deviate from the original.
Normal Tolerance
Indicates the maximum angle that the surface normals can differ from the original.
Import Hidden Objects
Converts objects from the original model even if they are hidden.
Display Hidden Objects
Changes the visibility of the imported hidden objects so they are shown in the converted
model.
Import Sheet Bodies
If the CAD application includes additional visual data that frame the 3D model itself, this
option includes these elements in the conversion.
Import Wireframes
Causes geometry that has no face data, though it is composed of ordered vertices, to be
converted.
Pass U3D File Through Unchanged
Imports a U3D model without changing its geometric data.
Maximum Aspect Ratio
Uses the maximum ratio of the rectangle size, helping to remove unnecessary triangles.
Grouping
Uses object grouping.
Polygon output
Lets you specify the polygon shape to be used while importing the file.
Import solids
Ensures that solids are imported in the file. Deselecting this option causes only wireframes
to be imported.
Import text
Imports any text that is part of the 3D model.
Import external references
Imports any external references included with the 3D model.
Optimize settings
Adjust the Optimize settings to change the balance between 3D quality and file size.
Reduce Polygon Count To
Removes triangles from the model. In 3D objects, parts consist of interconnected
polygons. The more polygons, the better the detail and the greater the file size.
Remove Parts Smaller Than
Removes parts that are smaller than the specified percentage of the entire 3D model size,
sacrificing quality for decreased file size.
Collapse Hierarchy To
Specifies the number of nested levels. A 3D model can be divided into parts, which can be
divided into parts, and so on. Collapsing the hierarchy to a certain number of levels
flattens all the parts below the specified level and may reduce file size and complexity.
Remove Duplicate Parts
Deletes duplicate geometric structures, such as those that overlap.
Remove Duplicate And Unused Materials
Strips out materials that either have duplicate versions or have not been applied to any
geometry in the 3D model, including embedded textures associated with those materials.
Export Normals
Includes the information for smoothing surface normals with the imported 3D model.
Surface normals store information about the contour of a mesh's surface.
Mesh Quality
Lets you lower Mesh Quality percentage to reduce file size.
JPEG
Uses JPEG compression. Texture maps can be compressed using JPEG compression at the
specified quality setting when they are embedded in the model. You can specify a lower
Texture Quality to reduce file size.
Enhance settings
The Enhance panel lets you determine animation and part color settings.
Animation
Lets you remove the animation, create exploding parts animation, or export (and possibly
modify) the current animation for any 3D model that includes animation. If you select
Create Exploding Parts Animation, select the number of stages the 3D model should be
split into.
If you select Create Exploding Parts Animation or Export Animation, you can rescale the
animation to a different length. Specify the absolute time in seconds or a percentage to
determine the length of the animation sequence.
Assign Random Colors To Parts
Uses different colors for 3D model parts to enhance contrast.
Transform settings
The Transform panel lets you change the position, scale, orientation, and units of the 3D
model.
Set Custom Scale
When you set a custom scale, Acrobat outputs the model with an embedded value that
specifies what length a model unit corresponds to.
Scale By
Changes the scale of the imported 3D file. For example, replacing 1 with 2 in the X, Y,
and Z boxes doubles the size of the 3D model.
Fit To
Changes the scale of the object to conform to the dimensions you specify.
Rotate
Specifies the angle of rotation for each axis.
Translate
Alters the position of the model in three dimensional space, relative to its origin.
Center Model At Origin
Translates the entire model so that the center of its bounding box is at the origin [0,0,0] of
the x, y, z coordinate. Selecting this option disables the Translate option.
