View Resolution
 AutoCAD
 Can
save time in zooming and panning at the
expense of display accuracy.
 Can provide a highly accurate display at the
expense of zoom and pan speed.
 The main factor is the view resolution.
Views and Viewports

View Resolution
 The
view resolution is the number of lines
used to draw circles and arcs.
 High
resolution values display smooth circles
and arcs.
 Low resolution values display segmented
circles and arcs.

 Set
view resolution by:

View Resolution
 The
variable VIEWRES
 Controls
the display smoothness of circles
and arcs.
 It can vary between 1 and 20000.
 Default setting is 100. Produces a relatively
smooth curve.
 A number < 100 causes circles to appear
more “jagged”.
 A number > 100 causes circles to appear
smoother.

Setting View Resolution
 AutoCAD
trades view resolution for
panning and zooming speed.
 The
View Resolution refers to the number
of lines used to draw circles and arcs.
Views and Viewports
11
Setting View Resolution
 Command
Sequence:
 VIEWRES:
 Do
you want fast zooms? <Y>
 Enter circle zoom percent (1-20000)
<current>:
A
number smaller than 100 causes more
lines to be used to draw circles and arcs.
Views and Viewports
12
Setting View Resolution
 If
speed is a concern, respond with Yes,
and AutoCAD uses fast zooms.
 AutoCAD
performs a REDRAW only when
zooming and does not perform a REGEN.
 If
speed is not a concern, respond with
No.
A
REGEN will be performed each time.

Views and Viewports
 Zooming
and panning can be time
consuming.
 Being
able to quickly specify and recall a
certain part of the drawing is much easier
than zooming or panning.
Views and Viewports
15
Creating Views
 VIEW
command allows you to create
named views which can then quickly be
recalled.
A
view can be any portion of the drawing.
Views and Viewports
16
Creating Views
 Think
of a view as a previously zoomed
display that you can recall at any time.
 Benefits
 Magnification
is the “right size”.
 Text is legible.

VIEWS by:
 Picking
Named Views button in the Viewpoint
toolbar.
 Select Named Views from the View pull-down
menu.
 Enter DDVIEW or V at the Command: prompt.

can spend a lot of time zooming and
panning.
 Aerial
View is a navigation tool that lets
you see the entire drawing in a separate
window.

Tiled Viewports
Chapter 9 – Page 374
Views and Viewports
54
Viewports
 The
AutoCAD Model tab screen may be
divided into several “windows” called
viewports.
 Each
viewport may display a different view
or zoom of the current drawing.
Views and Viewports
55
Viewports
 Another
type of viewport called “floating
viewports” can be created in the Layout
tab.
 Tiled
viewports - model space
 Floating viewports - paper space.
Views and Viewports

 Only
time.
 To
one viewport is active at any one
activate another viewport, click on it.
 When
active, the viewport border is
“thickened”.
Views and Viewports
57

 You
can draw between viewports.
 You
can start a line in one viewport and
complete the line in another viewport.

 Save:
 The
current viewport can be named and
saved.
 Names can be up to 31 characters

Views/Viewports
 Join:
 permits
merging one viewport with another
 one view is the dominant viewport; the other
viewport takes on the characteristics of the

Creating Tiled Viewports
 The
AutoCAD graphics window can be
divided into tiled viewports.
 Tiled model space viewports are created
with the VPORTS command.
 48 can be active at one time
 Only one viewport contains the cross hairs
at any one time.
 Preset tiled viewports can be selected
from an image tile menu.
Views and Viewports

Uses of Tiled Viewports
 Since
each viewport is a separate screen,
you can REDRAW or REGEN a single
viewport at a time without affecting the
others.
 REDRAWALL redraws all viewports.

 Creating
floating viewports in Paper Space
is very similar to creating Tiled Viewports
in Model Space.

view port configuration can be selected
from the Viewports dialog box.
