Basic Features and Functionality

Before you use AutoSketch, there are important features and functionality
that you should understand. Understanding the concepts in the following
sections is the key to a successful experience of doing this book's exercises. It
is strongly recommended that you read this material carefully. Each concept
is briefly defined here and described in detail afterward.
■ Entity. A single object, such as a line, polygon, or symbol.
■ Properties. An item of information assigned to an entity. Properties
include geometry, layer, pen, pattern, and so on.
■ Scale. The ratio between the size of an entity in its scaled output and the
size of the real-world object it represents. For example, if an entity that is
1/4 inch long in its scaled output represents a real-world object that is 1
foot long, the drawing scale is 1/4"=1'0".
■ Coordinates. A pair of numbers that together specify the location of a
point in your drawing.
■ Drawing Origin. The point that serves as a location reference for all
entities in the drawing. The x- and y-axes cross at the drawing origin. The
coordinates of the drawing origin are 0,0.
■ Reference Grid. An on-screen drawing aid consisting of a snap grid and a
pattern of lines, crosses, or dots that visually represent the grid.
■ Grid Origin. The point from which the axes of the reference grid extend
outward.
■ Snap. A means of entering points using the mouse or keyboard. You can
change the snap at any time during most Draw and Edit operations by typ-
ing the appropriate keyboard shortcut.
■ Lock Modifiers. Four modifications that you can apply to a snap. Lock
modifiers align input with the last point and are applied after the snap.
