DWF is an open format developed by AutoDesk (Design Web Format). Unlike DWG and DXF, DWF is focused on viewing only. It is intended to be used for publishing 2D and 3D CAD drawings so they can be easily viewed without requiring the use of CAD software.
ImageGear uses DWFToolkit for reading DWF file contents. The following tables use DWFToolkit terms to list DWF features supported by ImageGear:
