Run Sample Application

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

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.
Run the sample with appropriate arguments:

OdReadEx <filename> [MT] [DO] [DR] [PL] [DD]

`filename`	A full path to a drawing file to read data from.
MT	A loading data in multi threading mode.
DO	Disable the output of the progress meter.
DR	Disable dimensions recomputing.
PL	Enable partial loading.
DD	Only loading data without dumping.

If the application executed properly, you will see the source file loading progress and a database dump, that includes all information about the entities and object types located in the file. In case you get the "usage" message, check the parameters. An error message indicates problems with the source file.
