HOOPS Visualize package is shipped with different samples called Sandbox. These sandboxes are compatible with HOOPS Exchange but they need an additional setup detailled below.

## Instructions for HPS\_MFC\_Sandbox

1. Open the project properties from Visual Studio
2. Navigate to C/C++ → Preprocessor and add `USING_EXCHANGE` in the Preprocessor Definition

1. Make sure the HOOPS Exchange DLL are in the PATH or near the application executable:  
a. by using the environment variable `HEXCHANGE_INSTALL_DIR`. Its value must be the root of a HOOPS Exchange package  
**OR**  
2b. by copying the content of `HOOPS_Exchange/bin/win64` inside HOOPS Visualize bin directory

If the sandbox is correctly set-up, when running the Sandbox, the filters in File-\>Open shows HOOPS Exchange compatible CAD formats.
