How to use a progressbar in LISP functions?

To inform users about the progress of a lengthy calculation you can use progress bar ("thermometer"). In AutoLISP you can make use of the inbuilt function acet-ui-progress from Express Tools (must be installed).

Example - how to use it:

  
(acet-ui-progress-init "Working:" 10000); init - interval length

(setq i 0)

(repeat 10000; loop
; user functions performed here....
(setq i (1+ i))
(acet-ui-progress-safe i); update progressbar
)

(acet-ui-progress-done); dismiss progressbar
