Exercise complete

32. Running object snaps

If you need to use the same object snap repeatedly, you can set it as a running object

snap, which means it stays on until you turn it off. For example, you might set center

as a running objects snap if you need to connect the centres of a series of circles with

a line. As with single object snaps, the aperture, or the target box, indicates that an

object snap is on and identifies the selection area. You can change the size of the

target box. When you turn on multiple running object snaps, AutoCAD uses the

object snap most appropriate to the object you select. If two potential snap points fall

within the selection area, AutoCAD snaps to the eligible point closet to the centre of

the selection area. You can also at this point press the tab key to cycle through the

different object snaps set.

(a) Draw the following sketches on a new drawing.



26

(b) Set running object snap

Right Pick object snap at the bottom of the screenPick settings

Pick Object snap tab

Pick object snap on [F3]

Select clear all button

Turn on endpoint, intersection, centre, quadrant, and midpoint

Pick OK when you have finish select the object snaps

(c) Use the line command to draw the following lines. You might have to use the

tab key to switch the correct object snap that is required.

(d) To turn off object snap Pick object snap at the bottom of the screen

pick the icon)

Pick Real time from the drop down menu

Pick and hold the left mouse button down somewhere in the middle of the

drawing screen

Move the cursor up to make the drawing larger

Release the pick button

(c) Pan command

Start the pan command as above, then

Pick and hold the button down and move the cursor to a new position on thedrawing screen

Release the Pick button and then press enter to stop the command



28

(d). Zoom previous option

Exercise complete

Note: After a certain number times of zooming in, AutoCAD would stop zooming. To

go farther, stop (press ESC) the zoom command. Then type in regen and then press

enter. This should allow you to keep using the zoom command. Just repeat the regen

commands to zoom again even more.
