The previous syntax works only if the menu macro is part of a menu that is
on the AutoCAD for Mac menu bar and is available for use. For more
information about this syntax, see the AutoLISP Reference.
Preset Values
An application that uses block insertion presets could provide commands like
these: [Set WINWID][Set WALLTHK][Insert Window]
^C^C^P(setq WINWID (getreal "Enter window width: ")) ^P
^C^C^P(setq WALLTHK (getreal "Enter wall thickness: ")) ^P
^C^C_INSERT window XScale !WINWID YScale !WALLTHK
This code inserts the block named “window,” scaling its X axis to the current
window width and its Y axis to the current wall thickness. In this example,
the actual values come from the user-defined AutoLISP symbols WINWID and
WALLTHK. The rotation is up to the user to decide so that the window can
be rotated in the wall.
Resize Grips
With the following commands, grip size adjustment can be done on the fly:
^P(setvar "gripsize"(1+ (getvar "gripsize")))(redraw)(princ)
^P(setvar "gripsize"(1- (getvar "gripsize")))(redraw)(princ)
To add validity checking to these commands, values less than 0 and greater
than 255 cannot be used for the GRIPSIZE system variable.
Prompt for User Input
The following item prompts for two points and draws a rectangular polyline
with the specified points as its corners.
^P(setq a (getpoint "Enter first corner: "));\+
(setq b (getpoint "Enter opposite corner: "));\+
pline !a (list (car a)(cadr b)) !b (list (car b)(cadr a)) c;^P
