CAD FACTS 1

• You define a field by specifying its name, type, and width or precision.

• Graphic properties include layer, color, width, style, and pattern.

• A draw program creates an image by defining objects mathematically.

• Underlying each drawing is a database.• Auto-sketch keeps track of the scale of your drawing,

CAD FACTS 2

• Auto-Sketch expresses location in three ways: xy (Cartesian), polar, and isometric coordinates.

• Isometric drawings are usually used to create two-dimensional views of a three-dimensional object.

• The grid origin is similar to the drawing origin in function and appearance.

• Drawing scale is the ratio between the actual size of the entities in a drawing and their size on printed output.

• Layers help you place entities together in logical groups.
