Automatically Load ObjectARX Applications

Overview of AutoLISP Automatic Loading on page 436
Some ObjectARX samples contain an acad.rx file, which lists ObjectARX
program files that are loaded automatically when you start AutoCAD.
You can create or edit this file with a text editor or word processor that
produces files in ASCII text format, adding to or deleting from its contents to
make the appropriate ObjectARX programs available for use. As an alternative,
the APPLOAD command provides a Startup Suite option that loads the specified
applications without the need to edit any files.
Because AutoCAD searches for the acad.rx file in the order specified by the
library path, you can have a different acad.rx file in each drawing directory.
This makes specific ObjectARX programs available for certain types of drawings.
For example, you might keep 3D drawings in a directory called
AcadJobs/3d_dwgs. If that directory is set up as the current directory, you could
copy the acad.rx file into that directory and modify it in the following manner:
myapp1
otherapp
If you place this new acad.rx file in the AcadJobs/3d_dwgs directory and you
start AutoCAD with that as the current directory, these new ObjectARX
programs are then loaded and are available from the AutoCAD command
prompt. Because the original acad.rx file is still in the directory with the
AutoCAD program files, the default acad.rx file will be loaded if you start
AutoCAD from another directory that does not contain an acad.rx file.
You can load ObjectARX programs from an MNL file using the arxload
function. This ensures that an ObjectARX program, required for proper
operation of a menu, will be loaded when the menu file is loaded.
You can also autoload many ObjectARX-defined AutoCAD commands. See
Overview of AutoLISP Automatic Loading on page 436 and autoarxload in the
AutoLISP Reference in the Help system.
