Tetra 4D Converter Overview
############################

Tetra4D Converter allows you to create rich PDFs from supported 3D and CAD file formats and from
geospatially enabled PDFs. You can interact with 3D PDFs in several ways allowing you to rotate,
move, and measure parts and distances.

Insert 3D
-----------

This allows 3D CAD data to be converted and inserted into a PDF Document. When selected, you
define the position and size of the 3D annotation frame, then select the 3D source file. The file is
then imported and placed within your PDF document, after which you can manipulate the 3D image
as you like.


For more information see :doc:`conversion`.


Export 3D Data
--------------

This allows you to export and save 3D Data from your PDF in another file format. Supported file
formats for exporting include:

For more information about exporting, see :doc:`export`. Please
note that this functionality may change over time as file formats change and as Tetra4D Converter is
enhanced to support additional formats. Please see “U3D and PRC Formats” for more information.


Optimize 3D Data
----------------

Allows the 3D Data to be further optimized for file size and performance.


For more information see “Optimizing 3D Data”. Please note that this functionality may not be
available because of the format type. Please see “U3D and PRC Formats” for more information.


Replace 3D Data
----------------

Allows one 3D dataset to be easily replace with another.


For more information see “Replacing 3D Data”. Please note that this functionality may not be
available because of the format type. Please see “U3D and PRC Formats” for more information.
