Licensing options for this format begin with FME Professional Edition.
The 3D PDF Writer enables FME to write Adobe® Portable Document Format (PDF) files embedded with interactive 3D annotations.
The Adobe Reader software version 7.0 and above has included support for interactive 3D annotations in PDF files. These annotations allow users to visualize 3D models. For example, users can view the models from different angles and select sub-elements of the model by picking them with the mouse.
The writer represents the 3D models in the Adobe Product Representation Compact (PRC) file format, which become embedded in a PDF document. The 3D model can be viewed by PDF viewer applications that support PDF’s interactive 3D annotations. (See Compatibility, below.)
The 3D model has a hierarchical structure of Nodes, which are elements of the model:
- Feature types become Nodes with no geometry.
- Features become Nodes that may have geometries and attributes.
- Feature Nodes are children of their corresponding Feature Type Node.
Compatibility
To maintain backwards compatibility:
- Workspaces generated with 64-bit FME 2015+ use the PRC file format.
- Workspaces generated before FME 2015, running 32-bit FME 2015 or later, will use the U3D file format.
