Datasheet

There are two sets of temporary overrides, one for each hand (depending on whether

you’re right or left handed). One of your hands is on the mouse, right? We certainly wouldn’t

want you to let go of the mouse. The other hand

can hold down a key combo to temporarily over-

ride while you continue to use the mouse. (Then,

if you really practice, you can answer the phone

with your foot.)

This is the default list of temporary over-

rides, all of which can be customized with the

CUI command (see Chapter 10):

Left Hand Function

Shift+A Toggles object snap

Shift+S Enables object snap enforcement

Shift+E Object snap override: endpoint

Shift+V Object snap override: midpoint

Shift+C Object snap override: center

Shift+Q Toggles object snap tracking

Shift+D Disables all snapping and tracking

Shift+X Toggles polar tracking

Shift+Z Toggles dynamic UCS

Shift Toggles orthogonal mode

Crosshairs in 3D

If you’re planning to do any 3D modeling — and you should be, if you’re using AutoCAD 2007—

set up the crosshair cursor for 3D so you’ll know which way is up. Use the Options command,

and click the 3D Modeling tab.

Select Show Z Axis In Crosshairs. Doing so adds the third “up” dimension to the cross-

hairs; it appears in blue. There is a method to the madness of color coding. Anyone who

knows computers knows that monitors use RGB

color space. Painters often get confused because they

learned that yellow is a primary color, and it is — at

least, for the subtractive color you see with reflected

light (as in paint on a canvas). Computer monitors

shine light in your eyes, so they use additive color,

which is an entirely different animal. But we digress.

Right Hand Function

Shift+’ Toggles object snap

Shift+; Enables object snap enforcement

Shift+P Object snap override: endpoint

Shift+M Object snap override: midpoint

Shift+, Object snap override: center

Shift+] Toggles object snap tracking

Shift+L Disables all snapping and tracking

Shift+. Toggles polar tracking

Shift+/ Toggles dynamic UCS

Shift Toggles orthogonal mode
