ObjectARX technology is the premier API (application programming interface) that is supported by AutoCAD software, AutoCAD for Mac software, and the industry-specific AutoCAD software systems. If you need to access APIs that aren't exposed through AutoLISP programming language, if you want to create applications that are optimized for large data sets, or if you need to build efficient applications for Windows and Mac OS, ObjectARX technology may be the most effective API for you. This lecture will help you understand the basics of ObjectARX technology. We will discuss which development tools you need, how to interact with AutoCAD software, and how to create a very simple 'Hello World-esque' project. ObjectARX technology utilizes the C++ programming language, but this session does not require that you know C++. Prior AutoCAD software programming experience with AutoLISP programming language or Microsoft .NET is highly recommended. The second session of this series is a hands-on lab.
- Learn what ObjectARX technology is and discover what it has to offer
- Learn how to create a project in Microsoft Visual Studio 2012 or XCode
- Learn how to create a custom command and a custom function that accept some basic input and display a message to the user
- Learn how to load an ObjectARX technology application into AutoCAD software
