Trial versions require a subscription account, an electronically signed license agreement, and license activation.

  1. Log in at https://www.opendesign.com/trial
  2. Download Teigha Kernel package: Teigha_Kernel/Win32

    NOTE: The core functionality is provided within the Teigha Kernel package, which is a mandatory prerequisite to build all Teigha products.

  3. Choose a folder:
    • Teigha Vizualize/Win32 - Contains Teigha Vizualize trial version.
    • Teigha_Drawings/Win32 - Contains Teigha Drawings trial version.
    • Teigha_BIM/Win32 — Contains Teigha BIM trial version.
    • Teigha_Publish/Win32 - Contains Teigha Publish trial version.
    • Teigha_Architecture/Win32 – Contains Teigha Architecture trial version.
    • Teigha_Civil/Win32 — Contains Teigha Civil trial version.
    • Teigha_Mechanical/Win32 – Contains Teigha Mechanical trial version.
    • Teigha_Prc/Win32 – Contains Teigha Prc trial version.
    • Teigha.NET — Contains Teigha Drawings.NET, Teigha Architecture.NET and Teigha PRC.NET trial version.
    • Teigha.Java — Contains Teigha for Java trial version.
    • TeighaX – Contains TeighaX in TeighaX_vc10dll_ X.YY.N.lic.msi filename, where X is a major digit, YY and N are minor digits of the the Teigha version number.

    All trial version except TeighaX are represented as zip archives with "vcXXdll.lic" ending, where XX is the version number of Microsoft Visual Studio.

    NOTE: Archives for TeighaX, Teigha for Java, Teigha Architecture.NET, Teigha Drawings.NET and Teigha PRC.NET are not separated into the platform-dependent subfolder (Win32) like other product archives.

    TeighaX trial version is available only for the Visual Studio 2010 DLL configuration, therefore only TeighaX_vc10dll_X.YY.N.lic.msi can be downloaded.

    For all Teigha trial versions, except TeighaX:
    Unpack the downloaded files to your local drive (for example, C:\Teigha\Trial). If you use multiple Teigha products, you can unpack all files into one folder. First unpack Teigha Kernel, then unpack other downloads and overwrite existing files.

    NOTE: For Windows XP, install a proper Visual Studio Redistributable Package before generating license keys.

    For TeighaX trial version:
    Run the downloaded installation file and follow the instructions of the installation program.

    You must obtain license keys and activate the trial versions, otherwise no sample applications will start.

Generating License Keys and Activating Trial Versions

For All Teigha Trial Versions Except TeighaX

  1. Start the Trial Version Activator Application, located in exe - folder with prebuilt executables and DLLs.
  2. activatorIn the activator application window, enter your login and password obtained at the subscription step (these login and password are the same you used to download trial archives).
  3. Be sure that your Internet connected is available, because activator application tries to connect to the Teigha remote resources during the activation.
  4. Press Activate button.
    If Teigha product is successfully activated, activator application shows a message box with “Success” string.
  5. After successful activation, you can start using your Teigha product.

You can generate license key and activate trial version in manual mode without using activator application.

For TeighaX Trial Version

If you have an activated Teigha Core trial license on your computer:

  1. Copy TeighaLicense.ini from Teigha trial version folder to one of the following (* is the Teigha version number):
    • C:\Program Files (x86)\Common Files\TeighaX * for a 32-bit system.
    • C:\Program Files\Common Files\TeighaX * for a 64-bit system.

If you don’t have an activated Teigha Core trial license on your computer:

  1. Copy LicenseManagerApp.exe from one of the following folders (* is the Teigha version number):

    • C:\Program Files (x86)\Common Files\TeighaX * for a 32-bit system.
    • C:\Program Files\Common Files\TeighaX * for a 64-bit system.

    Place the file in any other folder where it can be run without elevated privileges (for example, a current user folder).

  2. Follow manual mode activation steps for Teigha Drawings Trial in that folder. Upon success, TeighaLicense.ini file is created.
  3. Copy TeighaLicense.ini which was created during the previous step back to (* is the Teigha version number):

    • C:\Program Files (x86)\Common Files\TeighaX * for a 32-bit system.
    • C:\Program Files\Common Files\TeighaX * for a 64-bit system.

TeighaX trial version is now ready to use.

You can generate license key and activate trial version in manual mode without using activator application.

Sample applications are pre-built in the exe\ folder and can be run immediately after activating the trial versions. At the command prompt, run any sample application without arguments to display information about its usage.

NOTE: If you run samples without a valid license key, errors display and the command prompt closes.

To use a sample, enter the sample application executable file name followed by arguments, for example:

OdCopyEx test.dxb test_copy.dwg

The following samples are recommended as a starting point for evaluating Teigha. For a full list of samples and their descriptions, go to: https://docs.opendesign.com/td/td_samples.html

Converting a Drawing File to a New Type and Version

OdCopyEx reads a drawing file and saves it as a new .dwg, .dxf, or .dxb file. It illustrates:

  • Teigha initialization
  • File loading into a database
  • Auditing of a loaded database
  • Saving a database to a specified file version and type
  • Assert function customization

See video at Teigha YouTube channel with OdCopyEx sample overview.

Reading a Drawing File

OdReadEx reads a drawing file and displays all information about the entities and object types located in the file. It illustrates:

  • Teigha initialization
  • File loading, including password-protected files
  • Parsing of a loaded database
  • Switching on entity/object types using protocol extensions
  • Accessing various object properties
  • Getting entity geometry via vectorization
  • Assert function customization

See video at Teigha YouTube channel with OdReadEx sample application overview.

Creating a Drawing File

OdWriteEx creates a new drawing, populates it with various entities, and saves to a file. It illustrates:

  • Creating various entities and objects
  • Freezing local time to create drawings with the same creation/modification time (useful for comparing created drawings while testing)
  • Providing a bitmap device for drawing preview creation
  • Using a custom AuditInfo object to save audit messages to a file
  • Using support files (fonts, etc.) from a third-party, if available
  • Saving a password-protected file
  • Assert function customization

See video at Teigha YouTube channel with OdWriteEx sample application overview.

  2. Build the solution to generate binary executable files and libraries for the samples. (Press F7 or choose Build > Build Solution).

    If the build is successful, binary output is placed in the exe\<configuration> folder.

  3. Modify or add your own code to the source code located in the Examples folder to further evaluate Teigha.

Building the Samples for TeighaX

There are no prebuilt samples for TeighaX, but trial users can build the samples from source code. Sample source code is located in the TeighaX trial version installation folder (usually C:\Program Files\Open Design Alliance\TeighaX * for 32-bit systems or C:\Program Files (x86)\Open Design Alliance\TeighaX * for 64-bit systems, where * is the Teigha version number).

To obtain binary files of TeighaX samples for .NET (located in Example/.NET subfolder), the following steps may be required:

  1. Open a solution, for example, sharpTest.sln.
    You can virtually use any version of Visual Studio supported by Teigha and upgrade the solution if it’s requested.

  2. Check whether the Platform property in the Visual Studio Standard toolbar is “x86 CPU architecture”. If yes, go to Step 6 to build the solution immediately. If no, continue to the next step.
  3. On the Standard toolbar, select “Configuration Manager...”.

  4. For each configuration (Debug/Release) you are going to build, do the following:

    • In Platform, select New. The New Project Platform dialog displays.
    • In New platform, select x86.
    • Click OK.

  5. Verify that the solution platform is updated as shown below, and then click Close.

  6. Build the example.
