Description

A simple console application that reads a .dgn file to a database, slightly modifies some elements and then saves the database to a V8 .dgn file.

Run Sample Application

To run the ExDgnReadWrite sample application, please do the following:

  1. Open the terminal and go to the directory where the sample binary file is built:
    • For Windows: <INSTALL_DIR>\exe\<PLATFORM_NAME>\
    • For Non-Windows OS: <INSTALL_DIR>/bin/<PLATFORM_NAME>/
    <INSTALL_DIR> is a directory where you unpacked the Drawings SDK archive.
    To determine your <PLATFORM_NAME> parameter, please see the ODA Platform Naming Conventions section in the Downloading Drawings SDK topic.
  2. Run the sample with appropriate arguments:
    ExDgnReadWrite <source file> <destination file> [MtLoading] [NoWait]
source file Full path to the source .dgn file.
destination file Full path to the destination .dgn file. Please note, that the extension of the file should be also specified.
MtLoading Enable multi-threaded loading.
NoWait Disable prompt.

If the application executed properly, the destination file will appear. In case you get the "usage" message, check the parameters. An error message indicates problems with the source file.
