FILLET
Fillets are common in mechanical drawings,but you can use the Fillet feature across all
design disciplines to create radius geometry
connecting two objects. FILLET creates acurved transition (actually an arc object)
between two nonparallel objects. FILLET can
also create a semicircular connection between
parallel lines.

FILLET
You can use the Fillet command to connect two
objects quickly with a smoothly fitted arc of a specified
radius. It is usually used to represent a rounded edge
on a corner. You can fillet lines, arcs, circles, ellipses,polylines, xlines, splines, and rays. You can also create
a sharp corner with the Fillet command by specifying a
radius value of 0.

FILLET,[OPTIONS]
:Reverses the previous action of the Filletcommand.
: Fillets all vertices of a polyline using thecurrent radius value.
: Sets the radius for the fillet arc. : When Trim mode is selected, the lines are
trimmed to be tangent with the fillet. If Trim modeis set to No Trim, the fillet radius is drawn but the
lines are not trimmed. : When the Multiple option is selected, you
can create multiple fillets without restarting thecommand.

POLYLINE
A polyline is a connected sequence of line
segments created as a single object. You can
create straight line segments, arc segments, or a
combination of the two..When drawing lines with the Line tool, each line
drawn is an object in its own right. A rectangle
drawn with the Line tool is four objects. Arectangle drawn with the Polyline tool is a single
object. Lines of different thickness, arcs, arrows
and circles can all be drawn using this tool.

POLYLINE
“Polyline” Command can be activated from one of
the following methods:
Draw Toolbar “Polyline”
Menubar Draw “Polyline”
Write “Polyline” on Command Line
Short Key “PL”

POLYGON
Polygons, like rectangles, are closed polylineobjects. Unlike rectangles, by default polygons areregular: They have equal length sides and equal
internal angles.The POLYGON command draws regular polygons of
a minimum of three and a maximum of 1024sides.
Regardless of the method you choose to definethe polygon, all of its sides are equal in length. If you want to draw irregular polygons, use the PLINEcommand.

POLYGON
“Polygon” Command can be accessed by one of
the following methods:
Draw Toolbar “Polygon”
Menubar Draw “Polygon”
Write “Polygon” on Command Line
Short Key “POL”

POLYGON
The default method for creating polygons is to specify a
center point and radius. When you choose this method,
you must choose either the Inscribed or Circumscribed
option. Depending on the option you choose, the size of the polygon is calculated as shown in the following
image.

POLYGON, [OPTIONS]
Draws a polygon within adesignated radius.
Draws a polygon outsideof a designated radius.
:Draws a polygon based on the number of sides and the length of a specified edge.
Note that you may pick any point for the center of apolygon, once it is made you will not be able tosimply snap to its center.

ARC
The Arc command creates an arc based on threepoints. Using the default method for creating an arc,
you specify a start point, a second point, and an end
point. The arc radius and center point are calculated
based on the position of the three consecutivepoints you specify.
The following illustration represents an arc being
created through three points.

ARC
“Arc” Command can be accessed by one of the
following methods:

ELLIPSE
An ellipse is a closed curve generated by four fixed points
defining major and minor axes and crossing at right angles
through the center point.
Ellipses can be regarded as what is seen when a circle is
viewed from directly in front of the circle and the circle rotated
through an angle about its horizontal diameter. Ellipses aremeasured in terms of two axes – a major axis and a minor axis
, the major axis being the diameter of the circle, the minor axis
being the height of the ellipse after the circle has been rotated
through an angle.

ELLIPSE
“Ellipse” Command can be activated by one of
the following methods:
Draw Toolbar “Arc”
Menubar Draw “Ellipse”
Write “Ellipse” on Command Line
Short Key “EL”

ELLIPSE,[OPTIONS]
Use this option to create an ellipse by defining thecenter point of the ellipse and then one endpoint foreach axis.
Use this option to add additional prompts to the
command sequence to create an elliptical arc or a fullcontinuous ellipse.
Use this option to create and ellipse or anelliptical arc. The first two points of the ellipse determine
the location and length of the first axis. The third pointdetermines the distance between the center of theellipse and the end point of the second axis.

HATCH
Hatch patterns are graphical elements that are
often used to represent materials, special
regions, or textures in a drawing. In addition to
using a pattern to define an area, you can usegradient or solid fill.
Hatching is used across all design disciplines to
enhance drawing views, to clarify designfeatures, and to show areas that were modified
in drawings when you communicate with your
clients.

HATCH
In order to show internal shapes of a solid being drawn in orthographic projection the solid isimagined as being cut along a plane and the cutsurface then drawn as seen. Common practice isto hatch the areas which then show in the cutsurface.
“Hatch” Command can be activated by one of thefollowing methods:
Draw Toolbar “Hatch”Menubar Draw “Hatch”
Write “Hatch” on Command Line
Short Key “H”
