Supported Platforms

C and C++ Support

To get started with HOOPS Exchange C API, see Set Up Your Environment

Platform	Architecture	Minimum Supported OS	Compiler
Windows	x64	Windows 10	MSVC v142
Linux	x64	CentOS 7 / Red Hat Enterprise Linux 7 (glibc 2.17)	devtoolset 8 GCC 8.2.3
Linux	arm64-v8a	Red Hat Enterprise Linux 8 (glibc 2.28)	devtoolset 9 GCC 8.3.0
macOS	x64/arm64 (Apple Silicon)	macOS 13.0 (Ventura)	XCode 15.1 (LLVM)
Android	x86_64/ARMv8A_64	5.0 (Lollipop)	Android NDK R18b Clang c++_shared
iOS	x86_64/arm64	iOS 12.5.7	XCode 15.1 (LLVM)

Microsoft Visual Studio Runtime Requirements

Starting from HOOPS 2023, HOOPS Exchange migrated its compiler to Visual Studio 2019 (previously 2015). Following Microsoft’s Documentation on binary compatibility, this change implies an update to the required MSVC redistributables.

HOOPS Exchange being an explicitly shared library, the impact occurs at runtime. Any application running HOOPS Exchange must have at least Visual Studio 2019 redistributable.

Deprecated Platform Supports

Starting from HOOPS Exchange 2024, support for Android x86 (32-bit) has been dropped. Starting from HOOPS Exchange 2024.2.0, support for Android ARMv7 (32-bit) has been dropped. Starting from HOOPS Exchange 2025, support for Mac OS versions lower than 13.0 have been dropped and for iOS versions lower than 12.5.7.

Visit our Developer Support page to familiarize yourself with support procedures, including deprecated functionality.

Format Support and Platform

CAD format support may be restricted in some platforms. Please refer to File Formats for more information.

Linux Specifics

In Linux systems, it’s important to explicitly set the platform locale options to ensure proper handling of text for some of our readers. Refer to your distribution’s documentation for instructions on setting locales and utilizing the LANG environment variable

Package Description

Here is a quick description of the package, once extracted:

Folder	Description
bin	HOOPS Exchange and 3rd party binaries
documentation	A link to this documentation
include	C include files
samples	A list of example programs made with HOOPS
tools	Misc helper tools for facilitating client code upgrades

Binaries

Binary files are located in a sub-folder of bin/ directory. The name of the sub-folder is set according to the runtime environment:

Platform	Folder	Main Binary File
Windows	win64_v142	A3DLIBS.dll
GNU/Linux	linux64	libA3DLIBS.so
Android	android/arm64-v8a
Android	android/x86_64
macOS	macos	libA3DLIBS.dylib
iOS	ios	libA3DLIBS.a

C# Support

To get started with C# development, refer to the Set Up Your Environment tutorial.

HOOPS Exchange C# API is available through the call bindings source files in the Developer Zone.

The API is supported on Windows, GNU/Linux, and macOS. Since the C# API is built on top of the HOOPS Exchange C++ binaries, all C/C++ requirements outlined in the previous section apply.

Additionally, the .NET Core 3.1 framework is required. You can download it from the official .NET Core 3.1 page.

Package Description

This section is a brief description of the C# API package contents.

Folder	Description
ExchangeCSharp	A single C# library provided as source files
samples	A list of example programs made with HOOPS

Source Files

The C# bindings are provided as source files rather that pre-compiled binaries. These source files are mainly located under a subfolder of ExchangeCSharp called Direct:

File	Description
API.cs	Support for Call Bindings
Classes.cs	High-level classes
Constants.cs	Definitions for Constant Values
Enums.cs	Definitions for Enumerators
Structs.cs	Data Structures
Library.cs	C# Library Loader
Utils.cs	C# Array Wrapper
hoops_license.cs	License key file.

For more information regarding the capabilities with the C# API, please refer to the C# API section of the documentation here.
