Technical Drawing and Design - First Nine Weeks
Review
(Please Note: also review the Classical Drawing
Study Guide)
Notes:
The T-Square allows the draftsperson to draw straight,
parallel lines.
In order to erase a small area precisely, we use
the eraser shield and white nylon eraser.
In geometry, a right angle has an exactly 90°
angle.
Adding clear, concise words on a drawing is the
practice of lettering.
The distance from the center of a circle to its
edge is the radius.
The thickness and darkness of a line is the lineweight.
The theorem that a triangle with sides that measure
3, 4, and 5 will always be a right triangle is the Pythagorean theorem.
In drafting, the instrument we use to measure
a drawing is the scale.
A form of projection that uses three axes to show
three sides of an object is Axonometric projection.
The weights and pressures carried by a structure
are the loads.
Drawing plans is drafting.
Planning out in a systematic way is designing.
The art and science of designing buildings is
architecture.
Making a likeness with lines on a paper is drawing.
A combination of imagination, knowledge, and curiousity
applied constructively is creativity.
The area on a drawing that contains information
about the student, period, and drawing description is the title block.
The distance across a circle through its center
point is the diameter.
The mathematical study of points, lines, angles,
surfaces and solids is geometry.
Circles that share a common center are concentric.
An oval shape with two centers of equal radius
is an ellipse.
A six-sided polygon is a hexagon.
Sets of numbers that describe specific locations
are coordinates.
Drawings in this class are graded using a rubric.
The decimal equivalent of 1/4 inch is 0.25.
Applied Portion:
Student will draft a multiview drawing of an object
at full scale, including a side view, front view, top view, and axonometric view.
Drawing will include standard border, title block,
dimensioning and lettering.
Note: Drawing will be graded with the mechanical
drawing rubric.
