Start BC without intial drawing template

Juraj Matel

I want starting BC without intial drawing template.

I try add "(command "CLOSE")" into on_doc_load.lsp, but it closing every opened file direct double click.

Is way how run BC without intial drawing template?

Using lisp this works:

Create an on_start.lsp with this content:
(if (zerop (getvar "dwgtitled")) (setvar "users1" "close")) (princ)

Create an on_doc_load.lsp with this content:
(if (= (getvar "users1") "close")
  (progn
    (setvar "cmdecho" 0)
    (command "_.close")
  )
)
(princ)

You could also use a start up switch and a script:
"C:\Program Files\Bricsys\Bricscad V10\bricscad.exe" /b "close.scr"
Content of close.scr:
close

Yep, the LISP works great for me as well.

Thank You,

For BricsCAD V14 you do not have to create two Lisp files. Only creating this on_start.lsp is enough:
[code](if (zerop (getvar "dwgtitled"))
  (progn
    (setvar "cmdecho" 0)
    (command "_.close")
  )
)[/code]

For V10 the solution with two files is required to avoid a command line message ('This command is available only when a drawing is open.').
