Known Issues
| Issue | Details and Workaround |
|---|---|
| Conversion fails | Input and output files must be on a local drive or a network drive mapped to a drive letter. If you are overwriting an existing PDF, make sure it is not currently open in Adobe Reader or Acrobat, since an open file will silently prevent the conversion from completing. |
| Gradient backgrounds do not print correctly | Adobe print drivers render gradient backgrounds as multiple bands when printing 3D PDFs. Use a solid color background (set the top and bottom colors to the same value) to avoid this. |
| 2D overlay objects | EVSPDFs support 2D overlay objects, but some have 3D equivalents that work better in the PDF viewer. Use legend 3d instead of legend, and titles 3d instead of titles. The add logo module is supported as-is. |
| Forward Facing Text | Forward Facing Text is not supported in 3D PDFs and cannot be rendered correctly. Avoid using it in any module, including post_samples and 3d titles. |
Adobe Acrobat Limitations
The following are limitations of Adobe Acrobat’s 3D engine that are outside of C Tech’s control:
- Measure Distance tool — should only be used with the model at Z Scale = 1. It cannot account for vertical exaggeration, so any distance measurement involving a difference in Z coordinates will be incorrect.
- Transparency — objects with an opacity less than 1.0 may not render correctly.
- Model Tree — Adobe automatically adds two parent levels to the model tree: model and EVS Scene.
