POLYGON

Polygon is any plane figure bounded by straight line, which are more than four in number.
If the polygon has equal angles and equal sides, it can be inscribed in ir circumscribed around
a circle and is called a regular polygon. If the side of polygon not equal, its called irregular
polygon. Type of polygon shown below:

mrm 65 ISOMETRIC DRAWING

In an isometric drawing, the object vertical line are drawn verticlly, and the horizontal line
in the width and depth plane are shown at 30 degrees to the horizontal. When drawn under
these guidlines, the line parallel to these three axes are at their true (scale) length. Line that
are not parallel axes will not of their true length.

mrm 65 OBLIQUE DRAWING

In this system, the main view is drawn as an orthographic projection (front view) and the
side view are represented on inclined planes. The angle between the orthogonal and
inclined plane is 45 degrees. The oblique view can be shown into three method:

a. Cavalier Oblique ( D )
b. Cabinet Oblique ( 1/2 D )
c. Common Oblique ( 3/4 D )

ORTHOGRAPHIC PROJECTION The word Orthographic is derived from the Greek words Orthos (straight, rectangular) and
Graphos (written, drawn). Orthographic Projection representation of three-dimensional solid
object on a two - dimensional surface. An Orthographic drawing has three views, showing the
top (plan), front and right side views. It may have dimensioning (measurements) of each part.
Orthographic Projection may be done using First Angle Projection (used in Europe) or Third
Angle Projection (used in America and Australia).

mrm 65 DIMENSIONS

The purpose of dimensioning is toprovide a clear and complete description of an object.
A complete set of dimensions will permit only one interpretation needed to construct the part.

Dimensioning should follow these guidelines:
a. Accuracy : correct values must be given
b. Clearness : dimensions must be placed in appropriate position
c. Completeness : nothing must be left out and nothing duplicated
d. Readability: the appropriate line quality must be used for legibility
