	Parasolid
	=========
	
	To enable Parasolid support, the sandbox must be compiled with the ``USING_PARASOLID`` preprocessor flag, and must be linked to *hps_sprk_parasolid.lib*.
	The *pskernel.dll* must be located in your system path. Or, for debugging, in the "Configuration Properties", under "Debugging" in the "Environment" field, set the PATH variable to
	
	*PATH=<PARASOLID_INSTALL_DIR>\base64_vXXX\dll\<LocalDebuggerEnvironment>*

	Also in the Configuration Properties, under Additional Include Directories for the C/C++ section, add the location of your Parasolid header files, for example:
	
	*C:\\parasolid\\parasolid_30.1.262\\base64_vXXX*

	In the Linker section of Configuration Properties, in the Additional Library Directories field, set the location of the Parasolid DLLs. For example:
	
	*C:\\parasolid\\parasolid_30.1.262\\base64_vXXX\\dll*
	
	The WPF sandbox requires that you add ``USING_PARASOLID`` to the list of "Conditional Compilation Symbols" in its project file, and you must add a reference to *cs_sprk_parasolid*.

	Additionally, some Parasolid files require schema files for import. For those files, it is necessary to set the schema directory using either ``HPS::World::SetParasolidSchemaDirectory`` or the ``P_SCHEMA`` environment variable. Alternatively, you can place the *schema* subdirectory in the same folder as the executable.

	Exchange-Parasolid
	==================
	
	To use the Exchange-Parasolid sprocket, follow the instructions above for  Exchange and Parasolid. In addition, your application must be linked to *hps_sprk_exchange_parasolid.lib*.

RealDWG
=======

Please note, you must be a RealDWG licensee in order to use the RealDWG interface. RealDWG is only available on Windows platforms.

To use RealDWG with the WPF sandbox, you must add ``USING_DWG`` to the list of "Conditional Compilation Symbols" in the WPF Visual Studio project file. You must also add a Reference in the Visual Studio project to *hps_cs_sprk_dwg.dll*. In the properties for the Reference to *hps_cs_sprk_dwg.dll*, set the Copy Local property to ``False``.

To enable RealDWG support in the MFC Sandbox, the project must be compiled with the ``USING_DWG`` preprocessor flag, and must be linked to *hps_sprk_dwg.lib*.

For more information on using RealDWG, please see the :doc:`Programming Guide </prog_guide/0909_loading_dwg>`.

Notes on Qt Sandbox
===================

For users of the Qt Sandbox, please note that we do not ship project build files other than the canonical Qt *.pro* format. Generation of Visual Studio projects, Xcode projects, and makefiles can be done through the Qt package's utilities.

**Mac users:** Starting with Catalina, macOS will now warn if dynamic libraries are loaded outside system directories or app bundles. If you see a message from Qt Creator when deploying the Sandbox saying the |HPSNOW| libraries appear to be "malware" or "may be corrupt" - it is because Qt Creator is trying to load the libraries stored outside the bundle. This can be resolved by going to the "Project" tab, navigating to the "Run" configuration, expanding the "Run Environment" section and modifying the ``DYLD_LIBRARY_PATH`` entry so that it doesn't include an entry for the |HPSNOW| package's *bin/mac* directory.
