3D XML

	This task explains how to customize the settings for the usage of the 3D XML format, a universal lightweight XML-based format for quick and easy sharing of 3D data, enabling rich PLM information to be easily incorporated into technical documentation, maintenance manuals, marketing brochures, websites, email communications and many other everyday uses.
	For additional information concerning the 3D XML format, see the following tasks in the Infrastructure Guide: Opening Existing Documents Saving Documents In Other Formats 3D XML Format

	The 3D XML settings page (Tools > Options > General > Compatibility > 3D XML) concerns the following settings categories: Export Geometry Representation Industry-Specific Extension Process Document Geometry Representation XML Tessellation Provides the representation of a part through a list of organized triangles (mesh) in XML format. Can be used for easy geometry exchange. Static Tessellation Compressed triangular mesh with static accuracy. If the assembly is in design mode, the accuracy used is the one specified in the visualization settings. If the assembly is in visualization mode, the accuracy of each component will be that of the associated CGR in the V5 Cache. Dynamic Tessellation Compressed representation containing a rough triangular mesh that can be refined when zooming in to discover details of the geometry (Dynamic Level of Details). The maximum reachable accuracy is provided by the user at generation time using the Accuracy setting. To benefit from Dynamic Level of details, use 3D XML Player or 3DLive (Explore and Examine window). When opening a 3D XML file with dynamic tessellation in CATIA V5, the dynamic tessellation is converted at open time to a static triangular representation (with the accuracy selected at generation) for compatibility reason. Export of Lineic Elements Lineic elements (wires, axis systems, points) are not exported by default in dynamic and Static Tessellation mode. To export these elements, you must check the option Tools > Options > Infrastructure > Product Structure > Cgr Management, `Save lineic elements in cgr`. Lineic elements are never exported in XML Tessellation mode.
	Note the following restrictions related to input documents: Dynamic Tessellation Available only if the Product is in design mode and references only CATParts. If the user tries to save an assembly which does not fulfill these conditions, a warning message will be displayed and the Product will be saved in static tessellation. XML Tessellation and Static Tessellation The user cannot specify the accuracy of the resulting 3D XML. If the assembly is in design mode, the accuracy used is the one specified in the visualization settings. If the assembly is in visualization mode, the accuracy of each component will be that of the associated CGR in the V5 Cache.

	Industry-Specific Extension To define the different industry-specific extensions corresponding to the applicative data you want to export, activate the corresponding radio buttons. Note: Only the extensions for which you have a license will be displayed. By default, all industry-specific extensions are activated.

	Process Document To define the Process Document object types to be exported, activate the corresponding radio button. By default, this option is valuated to `Export both ProductList and ResourceList`.
