1. Open a PDF, and choose Tools > Tetra4D Converter > Optimize 3D Data.

**Optimize Options:**


  - **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.

  - **Compress Tessellation**: Applies lossy compression to polygons.

  - **Remove B-Rep**: Remove geometry information of the 3D model from the PDF.

  - **Remove Attribute**: Remove attributes of the model from the PDF.
