use a ratio to indicate the amount by which the drawing is enlarged or reduced

A regular oval shape, traced by a point moving in a plane so that the sum of its distances from two other points is constant, or that results when a cone is cut by an oblique plane that does not intersect the base.

a sketch that displays dimensions and should display the different parts of the subject

the aesthetic drawing; just showing the object's looks, but still uses some sort of proportioning and ratio.

concerned with beauty or the appreciation of beauty

The process of creating a solid model or three-dimensional object using a modeling and design application on a computer.

A strategy in which geometry is defined in such a way that changes produce desired, predictable results.

a problem solving approach (also known as stepwise design) in which you break down a system to gain insight into the sub-systems that make it up.

A solid modeling technique where geometry is subtracted from existing model geometry.

A solid modeling technique where geometry is added to existing model geometry

typically includes top, front, and right-side orthographic projections and an isometric view of an object

Intersecting or lying at right angles; perpendicular.

Lightly drawn line to guide drawing other lines and shapes.

A heavy solid line used on a drawing to represent the outline.

A line that defines the center of arcs, circles, or symmetrical parts. A center line is half as thick as an object line.

shows the location of a hole, cylinder, or other round features on a drawing as a pair of perpendicular lines that cross at the center of a feature.

typically the front view in Fusion 360 or other 3D modeling software

An object that provides information about a feature, such as the length of a wall, the diameter of a fastener, or a detail callout. These objects can include dimensions, notes, or other types of explanatory symbols.

Something set up and established by authority as a rule for the measure of quantity, weight, extent, value, or quality.

Lines that are thin lines capped with arrowheads, which may be broken along their length to provide space for the dimension numerals.

Line which represents where a dimension starts and stops. Always has at least an 1/8" gap between the drawing and this line

Line which indicates dimensions of arcs, circles and detail.

aka 2D - A method of representing three-dimensional objects on a plane having only length and breadth. Also referred to as Right Angle Projection.

Term given to basic shapes added to a drawing.
