View ResolutionView 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.



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: Options dialog box from the Tools Menu.



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 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.


Setting View ResolutionSetting 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.


Setting View ResolutionSetting 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.

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.


Creating ViewsCreating Views

VIEW command allows you to create named views which can then quickly be recalled.

A view can be any portion of the drawing.



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.



Access 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.



The Named Views tab is where new views are defined.

The Orthographic and Isometric Views tab provides preset views around the drawing in AutoCAD.



A list of currently defined views is shown in the Named Views tab.



To make a view current: Click on the view and then click “Set Current.”

Or Double-click on the view.

The Aerial ViewThe Aerial ViewChapter 9 – Page 370Chapter 9 – Page 370


The Aerial ViewThe Aerial View

When you work on a large drawing, you 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.


Using the Aerial ViewUsing the Aerial View

To open the Aerial View Pick Aerial View from the View pull-down

menu OR

Enter AV or DSVIEWER at the Command: prompt.



The Aerial view window initially appears at the lower-right of the graphics window. It can be moved to any location on the screen. Drag window with the title bar.



The menu bar in the Aerial view contains three pull-down menus and three buttons. Zoom In Zoom Out Global



Zoom In Increases image magnification

Zoom Out Decreases image magnification

Global Displays the entire drawing area (zoom

extents) in the Aerial View window.



The Options pull-down menu contains: Auto Viewport Dynamic Update Real-time Zoom Aerial View Help



Auto Viewport Two settings: ON and OFF When ON, switching to a different tiled

viewport causes the new viewport to be displayed in the Aerial View window.

When OFF, the Aerial View window is not updated.



Dynamic Update Causes the Aerial View window to update

after each change in the drawing. Use only with “fast” computers.

Real-time Zoom Updates the drawing view as you Zoom and

Pan in the Aerial View window. Aerial View Help

Opens help.



Aerial View window is similar to the Zoom Dynamic command.

Right-click in Aerial View window to see short-cut menu.


Tiled ViewportsTiled ViewportsChapter 9 – Page 374Chapter 9 – Page 374


ViewportsViewports

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.


ViewportsViewports

Another type of viewport called “floating viewports” can be created in the Layout tab.

Tiled viewports - model space Floating viewports - paper space.


ViewportsViewports

Only one viewport is active at any one time.

To activate another viewport, click on it.

When active, the viewport border is “thickened”.


ViewportsViewports

You can draw between viewports.

You can start a line in one viewport and complete the line in another viewport.


ViewportsViewports

To access Named Viewports Pick the Display Viewports Dialog button from

the Standard, Layouts, or Viewports toolbars.

Enter VPORTS at the Command: prompt.

Select New Viewports from the Viewports cascading menu in the View pull-down menu.


Views/ViewportsViews/Viewports

Save: The current viewport can be named and

saved. Names can be up to 31 characters

Restore: You can recall a view at any time. Type the view name or enter a “?” to get a list

of all of the views. Delete:

deletes a viewport


Views/ViewportsViews/Viewports

Join: permits merging one viewport with another one view is the dominant viewport; the other

viewport takes on the characteristics of the dominant one.


Creating Tiled ViewportsCreating 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.


Uses of Tiled ViewportsUses 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 ViewportsCreating Floating ViewportsThe VPORTS CommandThe VPORTS Command


Creating Floating ViewportsCreating Floating Viewports

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



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

Use the VPORTS command.

The MVIEW command can also be used.



When Model Space is active, the Viewports dialog box creates tiled

viewports.

When paper space is active, the Viewports dialog box creates floating

viewports.



Use Spacing to set the space around the edges of the floating viewports.


The MVIEW Command OptionsThe MVIEW Command Options



MV, MVIEW or -VPORTS options: ON OFF Fit Hideplot Lock Object Polygonal



ON Activates the model space display within a

view port.

OFF Deactivates a model space display within a

view port.



Fit Default option. Creates a single rectangular floating viewport

that fills the entire printable area on the sheet.

The sub options 2, 3, 4 can be used to create multiple viewports.



Hideplot Prevents hidden lines in a 3D model from

being plotted.



Lock Locks the view in one or more viewports. When a viewport is locked, objects in the view

port can be edited and new objects added but:

Display commands like Zoom and Pan are disabled.


Creating Floating ViewportsCreating Floating Viewports Object

Use to change a closed object drawn in paper space into a floating viewport.

Existing Circles Ellipses Polygons and other closed shapes

can be used as floating viewport outlines.



Polygonal Draw a floating viewport outline using a

polyline. Any shape can be used.



OR Draw the shape in paper space using the

POLYGON command. Use MVIEW command Select Object sub-menu option to make the

object a viewport.

Zoom Scale has two options: nX

And

nX scales the display relative to the current display


Zoom To Paper SpaceZoom To Paper Space

nXP Scales the drawing in Model Space relative to

Paper Space. Is used primarily in the layout of scaled

multivew drawings. THIS IS THE MOST IMPORTANT ZOOM
