James Maeding of Hunsaker & Associates contacted me recently about an irritating problem that his users have with the AECOPEN command in Land Desktop. The AECOPEN command replaces the core AutoCAD OPEN command in AEC verticals. The problem they have is that AECOPEN displays an initial project dialog that requires users to press a [Browse] button to open the file browser dialog. Since they want to browse for a file every time they use the AECOPEN command, James wondered if I could create some code to automatically “press” the Browse button every time the AECOPEN command is issued.

I whipped up a little utility for AutoCAD 2007-2009 based products to do what James wanted, and it is now available on my freebies page as When the ARX module is loaded, AECOPEN behaves as if the user had immediately pressed the [Browse] button on the project dialog. If the [Ctrl] key is pressed, AECOPEN reverts to its original behavior.

Why not just use the built in OPEN command instead? The AECOPEN command has some important side effects, according to James.
