By default, when preparing an input 3D file by converting into the CDXFB format, CAD Exchanger stores all information available in the original file. Moreover, it will generate polygonal representation (used for display in a 3D view) in the case if the original file does not contain one.

CAD Exchanger allows to specify which data needs to be stored in CDXFB and thereby allows to increase speed of conversion, reduce storage space and memory footprint of the loaded model.

The following table specifies parameters in the settings file which are used by CAD Exchanger CLI which can be used to influence conversion to CDXFB format. For more information on CLI settings please refer to the CLI settings file format.

Name	Values	Default value	Description
[%7B8c4d235e-957b-428a-be5f-f3d3fa4cf9ec%7D] section
`savebrep`	`true` or `false`	`true`	Indicates whether to save BRep representation or not.
`savepoly`	`true` or `false`	`true`	Indicates whether to save Poly representations or not.
`preferredlod`	`fine`, `medium`, `coarse` or `any`	`medium`	Indicates granularity level used as filter for Poly representations export. When `any` value specified, all available lods will be saved.
`savetextures`	`true` or `false`	`false`	Indicates whether to save textures or not.
`saveproperties`	`true` or `false`	`true`	Indicates whether to save properties or not.
`savepmi`	`true` or `false`	`false`	Indicates whether to save PMI data or not.
