The Classmap provides a visual representation of how the objects in the ObjectARX, Managed. if you want additional information on the various other parts of the ObjectARX SDK, see the developer documentation. My main focus is on the developer documentation, so that is what this article will be focusing on.
Once downloaded, execute the EXE file to install the ObjectARX SDK which wants to be installed to an Autodesk folder under root drive of your workstation. The ObjectARX SDK, is essential, whether you are developing applications with C++ or VB.NET/C#. NET APIs, but also contains sample projects and most importantly the documentation for these two APIs (or most of it, more on that in a bit). The ObjectARX SDK is a set of not only library and header files that describe the AutoCAD ObjectARX and Managed. What is most important to you as a developer is where this documentation exists so you can do your job, and that is to write the programs that your customers or company expect. These two things aren't earth shattering by any means, but that is the general way I approach the organization of the AutoCAD developer documentation.
In most cases, milliseconds is now returned as "000" or a similar value that is not as accurate as AutoCAD 2016 and earlier. In most cases, the scripts and custom programs should work as expected with the exception of the milliseconds part of the time value being returned. In addition to those system variables, the following system variables are now accurate to the nearest second starting with AutoCAD 2017, whereas earlier releases they included milliseconds :Īny scripts or custom programs that use these system variables should be verified that they work properly with AutoCAD 2017. Recently, I mentioned that the CDATE and DATE system variables no longer store time down to milliseconds.
