Unless
you are the only person using the computer on which the drawing
has been constructed, it is best to save work to a USB memory stick or other
form of temporary saving device. To save a drawing to a USB memory stick:
1.
Place a memory stick in a
USB
drive.
2.
In the
Save in:
fi eld of the dialog,
click
the arrow to the right of the
fi eld and from the popup list select
KINGSTON [F:]
(the name of my
USB
drive and stick).
3.
In the
File name:
fi eld type a name. The fi le name extension
.dwg
does
not need to be typed - it will be added to the fi le name.
4.
Left-click
the
Save
button of the dialog. The drawing will be saved with the
fi le name extension
.dwg
- the AutoCAD fi le name extension (Fig. 3.10).
Snap
In previous chapters, several methods of constructing accurate drawings
have been described - using
Snap
, absolute coordinate entry, relative
coordinate entry and tracking. Other methods of ensuring accuracy
between parts of constructions are by making use of
Object Snaps
(
Osnaps
).
Snap Mode
,
Grid Display
and
Object Snaps
can be toggled on/off from
the buttons in the status bar or by pressing the keys,
F9
(
Snap Mode
),
F7
(
Grid Display
) and
F3
(
Object Snap
).
Object Snaps (Osnaps)
Object Snaps allow objects to be added to a drawing at precise positions in
relation to other objects already on screen. With Object Snaps, objects can
be added to the end points, midpoints, to intersections of objects, to centres
and/or quadrants of circles and so on. Object Snaps also override snap
points even when snap is set on.
To set
Object Snaps
- at the command line:
Command: enter os
And the
Drafting Settings
dialog appears ( Fig. 3.11 ).
Click
the
Object
Snap
tab in the upper part of the dialog and
click
the check boxes to the
right of the Object Snap names to set them on (or off in on).
When
Object Snaps are set
ON
, as outlines are constructed using Object
Snap icons and their tooltips appear as indicated in Fig. 3.12.
