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 C++ Class Library. If you use the Main C++ Class Library for loading, using the standard loading functions, you can modify the view port and view mode using the following functions:
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 LEADTOOLS Vector Formats.
