Properties
Properties, the individual qualities that define an entity, are divided into
three categories:
■
Geometric properties —those that define an entity’s size, position, and so
on. AutoSketch assigns geometric properties automatically as you draw
and edit.
■
Graphic properties —those that specify the appearance of an entity.
Graphic properties include layer, color, width, style, and pattern.
AutoSketch assigns graphic properties as you draw based on the current
settings on the property bar.
■
Fields —those you define yourself. You define a field by specifying its
name, type, and width or precision. A desk symbol, for example, could
have fields for model, size, color, and style. A resistor symbol for a printed
circuit board could have fields for resistance, wattage, and tolerance. You
can assign fields to any entity except a text entity, a marker, or a dimen-
sion. A field has two components: a field name, such as Manufacturer,
and a value, such as “AAA Casements.” Assigning this value to the
Manufacturer field of a window symbol attaches that information to the
symbol.
Coordinates
Coordinates are numbers that specify the location of one point in relation to
another. This relationship is classified as either absolute or relative. Absolute
coordinates reference the origin of the current coordinate system, for exam-
ple, the Drawing Origin, the Grid Origin, or the Page Origin. Relative coordi-
nates reference the last point you entered. They are useful when you want to
draw or place another entity a known distance from another entity or point.
