KEYS-UI and the Commandline:

The existing AutoCAD menu system is fundamentally flawed.  Can you imagine playing a piano using only a mouse to select keys?

The Keys to ACADUI's success are a substantial reduction in keystrokes plus ten fingers instead of one mouse.

Many drafters avoid the AutoCAD Command line because of long command names, and sometimes long or confusing aliases plus a need sometimes for multi-character responses to command options including some of both object-snap and object-select prompts. Most frustrating, however, is the resulting need for repetitive pressing of <enter> to confirm every input because of the irregular number of characters required to answer prompts. Also the comparative ergonomics of using a mouse or keyboard should not be overlooked. Mouse: Think of command, look for icon, move mouse, click menu icon, look for options, move mouse, click option or type option at keyboard and press <enter>..Keyboard:  Think of command, type one or two character alias, press <enter>, anticipate and press one key required response,  The mouse option requires repeated mind-hand-eye-hand coordination plus an <enter> per operation whereas the same can be achieved at the keyboard almost with the eyes closed but using ten fingers responding to mind-muscle memory. (Think of the pianist - not only play with one finger but press <enter> to confirm every keystroke).

KEYS-UI – How it works.

  • ACADUI has an Alias for EVERY ACADUI and AutoCAD command.
  • ACADUI Aliases are reduced to one, two and occasionally three keystrokes.
  • ACADUI Command options are ALL single character. (no <enter>)
  • ACADUI OSNAP options are ALL single character. (no <enter>)
  • ACADUI OBJECT select options are ALL single character. (no <enter>)

The single character OSNAPs and SELECTs defined for ACADUI commands are also viable as Ctrl+chr accelerator keys in generic AutoCAD commands (instead of typing three characters plus <enter>). The extended range of OSNAP and SELECT options defined for ACADUI commands are of course not available for generic AutoCAD commands.

KEYS-UI Aliases apply not only to ACADUI commands but can also be used to initiate generic AutoCAD commands simply by prefixing the ACADUI Alias with a back quote “`”. Thus PL starts ACADUI Place Line whereas `PL starts generic AutoCAD LINE.command.

KEYS-UI Function keys:

KEYS-UI uses single press Function keys to control the drawing environment.

KEYS-UI Extended keyboard:

KEYS-UI make use of the fifty plus keys on the keyboard and right mouse button not just the basic twenty-six alpha keys.


See what experienced professional drafters think about the keyboard vs. menus.

Professional CAD operators sooner or later find that keyboard shortcuts are physically and intellectually faster than using the mouse to pick through graphical menus.
