The World of AutoCAD Programming Platforms, Part 1

VBA remains an option, but its days appear numbered. Check out the other choices available for AutoCAD customization.

By Andrew G. Roe

AutoCAD's open architecture has long been one of its most appealing qualities. The freedom to customize menus, add custom commands, and develop add-on programs that run within AutoCAD has motivated numerous users to get under the hood and do some fine-tuning.

With AutoCAD 2013 now on the street, the options for programming AutoCAD remain robust, although the landscape continues to evolve. Autodesk has indicated for several years that Visual Basic for Applications (VBA), a programming environment introduced in the late 1990s, will eventually be phased out. VBA still has a pulse for the time being, but it appears to be on life support, as Autodesk is promoting Visual Studio.NET as the preferred development platform instead.

The .NET environment — which is more versatile and complex than VBA — has gained popularity in recent years, but has left some less-experienced programmers out in the cold. Meanwhile, the growth of mobile devices and cloud computing has introduced new considerations for CAD users and programmers. To better understand this shifting landscape, let's review various customization options, starting with the simpler methods and progressing to more complex alternatives.

Simple Customization

First off, AutoCAD offers plenty of customization options for non-programmers. Custom menus and commands have been achievable since the early days, before AutoCAD releases were tagged by year. Using customization tools from the AutoCAD ribbon, along with some behind-the-scenes work, you can customize the user interface, define external commands that invoke other programs from the AutoCAD Command prompt, create aliases for AutoCAD command shortcuts, and craft scripts to batch-process groups of commands.

AutoCAD 2009 introduced a macro recorder that allows you to automate frequently repeated tasks without typing any code. From the Manage tab of the ribbon, simply click the Record button to capture AutoCAD actions, the Stop button to end the macro recording, and the Play button to execute the macro. Read more »

PTC Introduces Modular Product Design Creo App and Windchill Mobile

Creo 2.0 includes updated versions of the nine original apps in the Creo family, plus a new tool for building 3D-based product assemblies, while Windchill expands to iOS devices.

By Cadalyst Staff

Earlier this week, PTC announced Creo 2.0, the latest release of its new generation of product design software. This follows the company's introduction last June of the first nine apps in the Creo family, which are intended to enable a wider range of roles to contribute to the design process with a set of integrated, purpose-built tools. With Creo 2.0, PTC introduces a new role-specific app supporting modular product design, and delivers productivity enhancements to its existing Creo apps.

At the same time, PTC announced the latest version of its Windchill product lifecycle management (PLM) software, which is now also integrated with its recently acquired Integrity software system lifecycle management technology. In addition, Windchill Mobile is now available from the Apple iTunes store for the iPad and iPhone. The new Windchill Mobile app gives users access to current product and process information from any location, and includes includes a "shake and break" capability that allows users to explode a product assembly by simply shaking their mobile device to see the internal parts in greater detail. Windchill also now supports Apple users even if they aren't on a mobile device, with support for Mac OS X. Read more »
