program

Aided Design)
part, circuit, building, etc.
Chamfer
A small angled surface formed between two surfaces.
Coincident
Occupying the same area in space.
Collinear
Lying in the same straight line.
Concentric
Circles or arcs that share the same center.
Constraint
A limit to a design process. Constraints may be such things as
appearance, funding, space, materials, and human capabilities.
A limitation or restriction.
Counterbore
A cylindrical recess around a hole, usually to receive a bolt
head or nut.
Countersink
A conical-shaped recess around a hole that is often used to
receive a tapered screw.
Design
An iterative decision-making process that produces plans by
which resources are converted into products or systems that
meet human needs and wants or solve problems.
Dimension Constraint Used to describe the size and location of individual geometric
shapes.
Documentation
The documents that are required for something or that give
evidence or proof of something. A drawing or printed
information that contains instructions for assembling, installing,
operating, and servicing.
Edit
A change or correction made as a result of editing.
Extend
Make larger in area.
Feature
A distinctive attribute or aspect.
Fillet
A rounded interior blend between two surfaces. Some uses are
to strengthen joining surfaces or to allow a part to be removed
from a mold.
Fabricate
Construct or manufacture an industrial product.
Fix
Attach or position securely.
Functional
Designed to be practical and useful.
Geometric
Restrictions applied to geometric entities; for example,

horizontal, parallel, perpendicular, and tangent.
Horizontal
Parallel to the X axis.
Isometric
A form of pictorial drawing in which all three drawing axes form
equal angles of 120 degrees with the plane of projection.

Vertical
A visual, mathematical, or three-dimensional representation in
detail of an object or design, often smaller than the original. A
model is often used to test ideas, make changes to a design,
and to learn more about what would happen to a similar, real
object.
The amount by which something is out of line.
Lines, planes, or surfaces side by side and having the same
distance continuously between them.
At an angle of 90˚ to a given line, plane, or surface.
A closed geometric figure in a plane formed by connecting line
segements endpoint to endpoint with each segment intersecting
exactly two others. Polygons are classified by the number of
sides they have, such as a triangle has three sides, a
quadrilateral has four sides, and a pentagon has five sides.
An outline of something as seen from one side.
A full-scale working model used to test a design concept by
making actual observations and necessary adjustments.
To move in a circle about a central axis.
A triangle that has a 90 degree angle.
Turning around an axis or center point.
The surface that 2D profiles can be sketched on.
A detailed description of the design and materials used to make
something
A straight line or plane that touches a curve or curved surface at
one point.
Cut off irregular or unwanted parts.
Parallel to the Y axis.
