Parsing is carried out at the request of data for any purpose (rendering, dumping contents, etc.). At the same time, the data is initially stored in streams for subsequent parsing. The TD_DwfDb.tx module can use partial loading, which is enabled by default. The open speed is an order of magnitude higher than when using imports. ODA Drawings Explorer uses this module to open. It uses the OdDbBaseDatabasePE extension protocol. This is a specialized read-only database for DWF, DWFX 2D, and DWFX 3D format files. TD_DwfDb.tx is located in the Components/Dwfdb folder. dwg database with the New command before using the Import command. ODA Drawings Explorer also uses the module but requires creating a new. The TD_Dwf7Import.tx module is used in the OdaMfcApp sample application in emulation mode when opening a. TD_Dwf7Import.tx is located in Drawings SDK. The following picture shows the DWF formats that are available for exporting an open database. The TD_Dwf7Export.tx module is used in the OdaMfcApp sample application and ODA Drawings Explorer. It is universal and can be used to export various databases by using the OdDbBaseDatabasePE implementation. TD_Dwf7Export.tx is located in Kernel SDK. There are three main toolkit-based support modules that are described in this article:

The source code for the toolkit is in the ThirdParty/DWFToolkit-7.7 folder and is built, as well as other third-party components, for many platforms.

DWF format support in ODA SDKs is based on the latest available version of the DWF Toolkit, version 7.7.
