The STARTUP system variable and the StartUpType environment variable

By Gopinath Taget

With the value of the STARTUP system variable set to 0, the user is only given the option of using a template. If it was set to 1, this would enable a user to 1) start a drawing from scratch, 2) use a template, or 3) use a wizard. You can of course control this programmatically.

(defun-q MyStartup ( / app doc)
  (vl-load-com)
  (setq app (vlax-get-acad-object)
        doc (vla-get-activedocument app))
  (if (= (substr (vlax-variant-value
                    (vla-getvariable doc "ACADVER")) 1 2) "17")
      (vla-setvariable doc "STARTUP"
        (vlax-make-variant 1 vlax-vbInteger)))
  (princ))
(setq S::STARTUP (append S::STARTUP MYSTARTUP))

You can change the default option for the dialog by setting the StartUpType variable as shown below:

;To start from Scratch
(setenv "StartUpType" "Scratch")

;To use a Template
(setenv "StartUpType" "T?emplate")

;To use a Wizard
(setenv "StartUpType" "Wizard")
