This tip is for making use of that
third, middle button, on your mouse.
For those of you who only have a two button mouse, it is
definitely time to upgrade to a three button
model right now! The
default behavior for a three button mouse in AutoCAD is to issue the RTPAN
command. If you have a mouse with two buttons and a
wheel, the wheel acts as the third button and issues the RTPAN command while
the RTZOOM command occurs if the third button is rolled.
This will allow you to use Real Time PAN or
ZOOM transparently without having to start and, most importantly,
end the commands. Not
that there isn't anything wrong with the RTPAN or RTZOOM
commands, but don't you use the SHIFT+Right-Click
to issue an override Osnap a lot more often?
Most power users just use ZOOM window and
ZOOM previous and decide to make the third
button bring up the Osnap menu rather than issuing
the Real Time commands.
There is a system variable for deciding
which mode will be employed. The MBUTTONPAN variable will issue the Osnap
menu if set to (0) and issue the RTPan/ RTZOOM
command if set to (1). Some software drivers
for the three button mouse allow multiple choices for setting the default
behavior of the third button in the Windows Control Panel under Mouse.
Most of the time a setting of "Middle
Button" is required for this feature to work properly in AutoCAD.
You may have to do some trial and error on
the these settings if there is no "Middle Button" setting.
The really advanced users and
programmers can write a little Diesel language into your menus to bring up a
custom pop-up menu of your own. |
