I’m a member of ODA (not a trial user). How to activate ODA Products?

1. Choose ODA Product and find dependencies on the scheme. Download necessary archives, for example:

  • For Civil SDK download Kernel, Drawings, Architecture and Civil;
  • For Drawings.NET SDK download Kernel, Drawings, and Drawings.NET;
  • For Architecture.NET SDK download Kernel, Drawings, Drawings.NET, Architecture, and Architecture.NET.

Please do not mix archives with different configurations:

  • dll - indicates dynamic link library version
  • md, mt - /MD, /MT, etc. Visual Studio compiler options (static library)
  • dbg - indicates the presence of debug information (/mtd, /mdd, etc.)

2. Unpack downloaded archives and merge them in one folder.

3. Get ODA Activation Information.

4. After login, check your activation name, and if it is correct, choose a version of the ODA platform you use and click the Generate.

What is the difference between archives with dll, dlldbg, dllrwd, md, mddbg endings?

These archives have different configurations:

  • dll - indicates dynamic link library version;
  • md, mt - Visual Studio compiler options (static library);
  • dbg - indicates the presence of debug information (/mtd, /mdd, etc.);
  • rwd - release build containing debug information (useful for reproducing certain types of runtime problems);
  • amd64 - libraries built for the x86 AMD64 platform.

More information about naming conventions for archivescan be found here.

You shouldn’t mix archives with different configurations (even mixing dll and dlldbg can cause exceptions).

Why I see a warning 'It made by unauthorized application' in AutoCAD when trying to open dwg file created with ODA SDKs?

How should I configure the project in Eclipse (I am using Java 8)?

Open the Project Properties in Eclipse and switch to Java Build Path -> Libraries. Add the .jars to the project and specify the "Native library location" setting. Point to the exe/vc10 folder with all of the .exe and .dll files activated.

Is there a way to detect whether a drawing was created by ODA or another application?

The TDFILEPRODUCT command prints to the console either an ODA version string or "Unknown": TOOLKIT_EXPORT OdString odFileWasSavedBySoftware(const OdDbDatabase* pDb); This function is not declared in Include headers.

Is it possible to load DLLs and TX files from a different folder than where the main application is installed, e.g., a subfolder of my installation such as ODA\DLLs?

For DLLs and .tx modules you link with, it is the same as for any other DLLs. Their folders should be in the PATH variable.

For .tx modules that are not linked (loaded dynamically with loadModule()), you can override OdRxSystemServices::findModule() and return the full path.
