Hi.
I tried changing the viewpoint through a command ((command "-vpoint" "1,0,-1")) in a lisp and I'm getting Nil as return.
is there a way to use "-vpoint" command in a lisp?

thanks,
aridzv.

*edit:
for now I'm using a saved view by the name of "TOP-FRONT-RIGHT" and load it with this command:
(command-s "-v" "Restore" "TOP-FRONT-RIGHT")

    (command "-vpoint" "1,0,-1") removed the extra brackets.

    The extra brackets is not used in the code...
    And for your first question - yes.
    Since you and others insist it should work Maybe it is a bug - I'll send a support request.
    Thanks anyway.

    (command ...) always returns nil, it does not mean the function or the command failed.

    Hi Roy and thanks for the reply.
    the command dosn't change the view point.
    about the Nil - it is true what you wrote,I've been explained erlier that if I add (princ) after the command in the lisp it will not return Nil.

    but still - when I run the command,both from command line and from a lisp it dosen't change the viewe point...

    regards,
    aridzv.

    EDIT:
    I must add that if I type the command in the command line an maually type the values it dose work...
    I just can't make it work through a lisp...

    In V18 (command "-vpoint" "1,0,-1") works.

    so in v23 it is probably a bug (and also in V22...).
    I've sent a bug report to the support.

    in the mean time I aded views to my template file (named "TOP-FRONT-RIGHT" and "REG"),
    and then I use lee mac StealV1-8.lsp to load them to my drawings from the ON_DOC_LOAD.lsp and ON_START.lsp,
    and then change them from a lisp this way: (command-s "-v" "Restore" "TOP-FRONT-RIGHT")

    the problem solved by bricscad support team.
    apperntaly my user profile was currpted in some way (maybe to much lisp experimants... :D ).
    I've re-load the default user profile and the command is working.
