Comments

A 3D file format usually doesn't have a physical size. The user can specify a viewport (physical size up to which the drawing can be rendered) with LFileSettings::SetViewport2D. How the drawing is to be rendered inside this viewport depends on the current viewport mode set with LFileSettings::SetViewMode2D. Default viewport size is 640x480 pixels.

When working with DXF files, you can use the Vector features, available in selected products, or you can use the Main Class Library. If you use the Main Class Library for loading, using the standard loading functions, you can modify the view port and view mode using the following functions:

LFileSettings::GetViewMode2D

LFileSettings::SetViewMode2D

LFileSettings::GetViewport2D

LFileSettings::SetViewport2D

This function may be used with the following Vector file formats: DXF, DWG, WMF, EMF, PCT, CGM, DRW, PLT, TIF (with a DXF saved internally) and Intergraph Vector. For more information on these file formats and their availability, refer to Summary of All Supported Image File Formats.
