1. Displaying Objects

2. Objectives
After completing this lesson, you will be able to:
• Identify tools that control the drawing view
display.
• Use the Pan Realtime command to perform
real time pan operations in the drawing.
• Use the Zoom Realtime command to perform
real time zoom operations in the drawing.
• Use different Zoom commands to control the
view magnification.
• Use a wheel mouse to zoom and pan in the
drawing.
• Use the Regen command to regenerate the
drawing.

3. Display Tools
• Most of the time you will use the wheel
on your mouse to zoom in and out of
display views in your drawing. Additional
zoom tools are located on the Navigate
panel in the View tab on the toolbar
ribbon.

4. Display Tools
• You can reposition the center of your view
on the drawing by using the Pan
command. Just like panning with a video
camera, panning your drawing changes
only the position of your view of the
drawing, not the location or magnification
of objects in the drawing.

5. Display Tools
• You can reposition the center of your view on the drawing by
using the Pan command. Just like panning with a video camera,
panning your drawing changes only the position of your view of
the drawing, not the location or magnification of objects in the
drawing.

6. Command Options
• While in the Pan command you may access other Pan and Zoom
options when you right-click in the drawing window to display a
shortcut menu.

18. Wheel Mouse Features
• The wheel mouse is a variant of the
standard pointing device that is modified
with a small wheel between the left and
right buttons.
• You can rotate this wheel in small
increments.
• You can use the wheel to zoom and pan in
your drawing without using any
commands. When zooming in, the
location near your cursor is the focal point
of the zoom and thus remains on the
screen.
• The ZOOMFACTOR system variable
controls the incremental change, whether
forward or backward.
• The higher the number of the variable,
the greater the zoom.

19. Wheel Button Modes
You can set the wheel button to function in two different modes. The value of the MBUTTONPAN
system variable controls whether panning is supported.
• If MBUTTONPAN is set to 1, the PAN command is activated when you use the wheel.
• If MBUTTONPAN is set to 0, the Object Snap menu is displayed when you use the wheel

20. Regen
• Use the Regen command to regenerate all
the geometry in the drawing.
• Use the Regenall command to regenerate
all the geometry when there are multiple
drawing viewports.
• When you regenerate the drawing, the
screen coordinates for all objects in the
drawing are recomputed and the drawing
database is reindexed for optimal display
performance.

21. Guidelines When Regenerating Large Drawings
• Because regeneration recalculates the screen
coordinates for all objects in the drawing, it usually
takes longer to regenerate large drawings than
smaller ones.
• If you experience performance decreases on larger
drawings, consider setting REGENMODE = 0 to
prevent automatic regeneration.
• You can manually regenerate the drawing when you
need to.
