/b

Script name

Designates a script to run after you start the program (b stands for batch process).

If the script file is in the Start In folder, a full path to the script file is required
unless this security measure is suppressed either by including the /six command line
switch, or setting the LEGACYCODESEARCH system variable to 1.

Scripts can be used to set up drawing parameters in a new drawing file. An SCR file
type is assumed.

/ld

ARX or DBX application

Loads a specified ARX or DBX application. Use the following format:

<path<filename.ARX

If the path or file name contains spaces, then the path or file name should be wrapped
in double quotes. If no path information is included, the program search path is used.

The same security measure as described in the /b switch applies to ARX and DBX files.

/nologo

No product logo screen

Suppresses the logo screen at startup.

/p

User-defined registry profile

for starting the program

Specifies a user-defined registry profile for starting the program. The selected profile
is in effect only for the current session of the program, unless you make another
profile current in the Options dialog box during that session.

You create or import profiles on the Profiles tab in the Options dialog box. With
the /p switch, you can specify the name of a profile that is listed in the Options
dialog box or the file name of an exported profile (ARG) file. If the profile does
not exist, the current profile is used.

/r

Default system pointing device

Obsolete. Restores the default system pointing device. It creates a new configuration
file (acad20xx.cfg) and renames the previous configuration file to acad20xx.bak.

/safemode

Disable all executable code

Prevents all executable files from loading and executing in the current session. This
switch is useful for stopping and locating malicious executable code.

/six

“Start In” execution

Allows searching for executable files in the “Start In” folder of the program. The
Start In folder is specified in the program’s shortcut icon, or the folder in which
a DWG file is doubled-clicked to start the program.

As a security measure, searching for executable files in the Start In and drawing
folders is suppressed unless the LEGACYCODESEARCH system variable is set to 1. The
/six switch provides an exception to allow searching in the Start In folder even when
the LEGACYCODESEARCH system variable is set to 0.

/v

View name

Designates a specified view of the drawing for display at startup.
