Frequent tip contributor Leonid Nemirovsky offered this tip. "Starting with AutoCAD 2007 and up, another switch was added to AutoCAD icon:
/w "myworkspacename" (replace "myworkspacename" with your own
"This switch specifies which workspace is to be restored at startup. The workspace must be in one of the loaded CUI files, main, enterprise, or partial. So the icon property Target box may look something like this:
"c:Program FilesAutoCAD 2009Acad.exe" /w "myworkspace
"More AutoCAD icon switches can be found in this PDF at www.hyperpics.com."
NOTES FROM CADALYST TIP PATROL: As always, Lee Ambrosious' www.hyperpics.com continues to be a great user resource.
This tip, of course, would be of the greatest utility in a multiple-users-on-one-workstation environment. Single users probably won't have a real need for this (unless they have seriously different workspaces for different disciplines and prefer to "switch" from, for example, architectural to electrical via a desktop AutoCAD icon rather than within AutoCAD via the Workspace toolbar or command.
It's always a good idea to review the usefulness of switches, especially if most of the drawings being used are notably similar. The default Workspace can also be set by typing in Workspace and selecting setCurrent.
