Lesson 3 Flashcards
This command will insert a point marker in your drawing at a position
which you pick or at any coordinate location which you enter in the Command
window
Point (PO)
__________Creates a straight_______. It is used to draw _____ continuously. Each
segment is a _________ that can be edited separately.
Line (L), line segment, lines, line object
Continues a line from the endpoint of the most recently drawn line.
CONTINUE
End the line segment at the beginning of the first line segment, which forms a
closed loop of line segment
CLOSE
Erases the most recent segment of a line sequence.
UNDO
This command creates a line of infinite length which passes
through two picked points.
Construction line (XLINE)/(XL)
They are very useful for creating construction
frameworks or grids.
Construction Lines
They are not normally used as objects in finished
drawings.
Construction Lines
Construction line options
• Hor
• Ver
• Ang
• Bisect
• Offset
Creates a horizontal construction line.
Hor
Creates a horizontal construction line.
Hor
Creates a vertical construction line.
Ver
Creates a vertical construction line.
Ver
Creates a construction line at a specified angle.
Ang
Create a construction line that bisects an angle defined by 3 points.
Bisect
Creates a construction line that is offset from an existing line by a specified
distance.
Offset
The segments of this command are connected, when using it, all line segments are one object
Polyline (Pline)/(PL)
A ________ of sides ranging from 3 to any number can be drawn using ___________
Polygon, Polygon Command
Defines the center of the polygon.
Centre of Polygon
Specifies the radius of a circle on which all vertices of the polygon
line.
Inscribed in Circle
Specifies the distance from the center of the polygon to the
midpoints of the edges of the polygons
Circumscribe about Circle
Defines a polygon by specifying the endpoints of the first edge.
Edge
Specifying the radius with your pointing device determines the _____ and ________ of the
polygon.
Rotation, Size
Specifying the radius with a value draws the _________ of the polygon at the
current ________.
Bottom Edge, Current snap rotation angle
This command is used to draw an arc accurately.

-Direction values
In what directions are arcs drawn by default?
Counter clockwise
Draws an arc
Start point
Defines the radius of the circle.
Center Point and Radius
Defines the diameter of the circle.
Center point and Diameter
Draws a circle based on three points on circumference.
3P (Three Points)
Draws a circle based on two endpoints of the diameter.
2P (Two Points)
Possible ways of drawing the circle
-Center point and Radius
-Center point and Diameter
- 3P (Three Points)
- 2P (Two Points)
Default way of drawing a Circle
Center point and radius
Ellipse command
Ellipse (E)
The default
option in drawing an ellipse is to pick the ____________ and then a __________ to define the
_________ of the ellipse.
two end points of an axis, third point, eccentricity
A special type of polyline which is made up of arc segments
