ADOBE ACROBAT 3D VERSION 8 393 User Guide PRC Compress B-rep To The amount (in millimeters) of lossy compression applied to geometry. For best results when exporting geometry, set the amount to 0.001 or leave this option unselected. You can compress the geometry after you convert the 3D file to PDF by right-clicking the 3D model and choosing Optimize PDF. Compress Tessellation Applies lossy compression to polygons. U3D Mesh Quality Controls the quality relative to the percentage of lossy compression applied to the image files. Higher percentages indicate less compression and better image quality. A setting of 100% applies no compression. Texture Quality Specifies the quality for textures. Lower values reduce 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 Eliminates parts that are smaller than the specified percentage of the entire 3D model. Use this option when a reduced file size is more important than visual quality. Collapse Hierarchy To Specifies the number of nested levels. A 3D model can be divided into parts, and those parts 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 haven't been applied to any geometry in the 3D model, including embedded textures associated with those materials. Remove Normals Removes any smoothing normal information. Surface normals are used to store information about the contour of a mesh's surface. Enhance tab The Enhance settings determine animation options and part colors. These settings are available for U3D format only. Remove Animation Removes the animation associated with the 3D model from the conversion. Create Exploding Parts Animation Sets the number of stages the model should be broken up into. Each resultant stage lasts a second in duration. Export Animation Controls the animation by removing redundant animation keyframe data, reversing the animation sequence, or rescaling the animation to a different length. If you want to rescale the animation, specify the absolute time in seconds or a percentage to determine the length of the animation sequence. Assign Random Colors To Parts Randomly colors each discrete part of a 3D model, emphasizing the individual parts. Transform tab The Transform options specify the position, scale, orientation, and units of the 3D model. Set Custom Scale Embeds a value in the model output describing the proportion between length units (such as inches or centimeters) and the displayed model units. Scale By Changes the scale of the imported 3D file. For example, replacing 1 with 2 for 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.
