Drawings depicting construction methods using:
Blending of lines and curves
A diagram depicting how to blend a line between a line and a circle using an arc.
Tangency
Constructing a tangency with one circle with one radius in AutoCAD
Circle
A circle that was constructed using the radius function on AutoCAD.
Free hand and sketches
Bending of lines and curves
Tangent
Circle
Evidence of research on the different construct method
Description of blending of lines and curves
Blending of line is used for only simple type of outline composed entirely of straight lines. Thus,
the inclusion of curves within the outline of a component is vital for several reasons which are to
eliminate sharp edge, stress Centre, extra machining. Thus, making a component more efficient
and attractive. It is important that they be attractive so that they, surpass other competitors'
products and make interesting for customers. It is not simple these days to construct machines
with difficult shape. Therefore, blending of line allows complex outlines and edges on machines
to be simply manufactured as cheaply and easily. Thus, the blending of lines and curves plays an
increasingly important role in humans everyday life.
CHNICAL
AWING
Tangency
Is the contact of a single points or along a line without crossing.
Description of Circles
A circle is a closed, two-dimensional curved shape figure that has no corners or edges that uses
radius, diameter and circumference for measurements.

REFLECTIVE STATEMENT
From the technical drawing school-based assessment done, the Researcher has learned new skills
in the technical drawing field. Also, the researcher now has the ability to use and apply all his
knowledge collected from this research. Thus, allowing the researcher to learned more about
bending of lines and curves, tangency, and circle. The researcher can now use and apply his
knowledge in AutoCAD on more advance types of drawings on his own. Thus, this has been a
vital step to understand more advanced field of drawing.
