Lesson 4 Flashcards
These are
essential modes and methods of entering data that, once mastered, allow
you to create measured drawings with ease.
Drawing Aids
What are the Drafting Aids
Limits
Layers
Dimensioning
Object snap
Object snap modes
Zoom
These are used to set the boundaries of the drawing.
Limits
It is like a clear piece of paper that can be laid directly over the drawing. Used to control the visibility of objects and to assign properties such
as color and linetype.
Layers
Horizontal, vertical, aligned, and radial dimensions can be created with the ____
command.
DIM (dimension)
It can help establish and enforce drafting standards.
Dimension styles
It provide a way to specify precise locations on objects whenever
you are prompted for a point within a command
Object snap
Object snap modes
Midpoints
Center
Node
Quadrant
Intersection
Extension
Insertion
Perpendicular
Tangent
Apparent intersection
Nearest
Parallel
Select all
Clear all
This command enlarges a rectangular area of a drawing
based on a defined window using the cross hair
Zoom window
This command displays the are of the drawing limits or extent
whichever are greater.
Zoom all
Pans and zooms using a rectangular view box
Zoom dynamic
Zooms to change the magnification of a view using a scale factor
Zoom scale
Zooms to display a view defined by a center point and a
magnification value or a height.
Zoom center
Zooms to display one or more selected objects as large as
possible and in the center of the view.
Zoom object
Zooms interactively to change the magnification of the view
Real time
Zooms to display the maximum extents of all objects
Zoom extends
Zooms to display the previous view. You can restore up to 10
previous views
Zoom previous
The Window option is invoked by typing ___ in response to the “Select objects”
prompt. Window allows you to define a rectangle using two points in exactly the
same way as the RECTANGLE command. Once the window is defined, all objects
which lie entirely within the window wil
W
The Crossing Window option is invoked by typing ___ at the “Select objects”
prompt and is a variation of the Window command.
C
enter ___ at the next “Select objects” prompt to remove the
objects previously added
U (undo)
You can
use this option to select all the objects in the current drawing, no picking is
required
All selection
allows you to draw a multi-segment line, like a Polyline. All
objects which cross the fence will be selected
Fence selection
similar to the Window
option except that you can define an irregular polygon shape within which
objects will be selected
Window Polygon Section
allows you to define a rectangle using two points in exactly the
same way as the RECTANGLE command.
Window selection
The command sequence is
exactly the same but objects are selected which lie entirely within the window
and those which cross the window border.
Crossing Window selection
When drawings become complicated it is sometimes difficult to select the
particular object you want because it is either very close to or overlies another
object what selection u should use?
Object cycling
You can remove selected objects
from a selection set just as easily by _______ picking.
Shift
