and the Vertical lock modifier, the square AutoPoint Indicator identifies the endpoint nearest the pointer, but a dotted line extends to the potential snap point based on the current snap and lock modifier. AutoSelect A feature that automatically selects the last entity drawn when you cancel most Draw and Edit commands. AutoSelect also highlights the last entity drawn while using a Draw command. When AutoSelect is active, changes you make on the edit bar affect both the highlighted entity and the entity you are currently drawing. AutoSnap A drawing aid that allows you to draw with more precision by automatically identifying exact points such as an entity's midpoint, endpoint, or centerpoint. AutoSnap has two modes, MultiSnap and Single Snap. See also Multisnap mode and Singe Snap mode. axis An imaginary line used as a reference for positioning or manipulating entities. See also x-axis, y-axis, z-axis and alignment axis. background layer A layer on which entities are visible but not editable. See also editable layer and masked layer. backup file A duplicate drawing file created to safeguard data in the original file from accidental loss. AutoSketch creates backup files automatically when the Create Backup File option is checked on the File page of the Drawing Options dialog box. Backup files normally have a .BAK extension. base entity An entity that consists of a single drawing element such as a line, arc, or circle. See also entity. baseline dimensioning A type of dimensioning in which each dimension in a series of linear dimensions is measured from a single extension line. See also chain dimensioning and single dimensioning. basepoint A reference point used for positioning or manipulating entities in a drawing. See also rotation basepoint, symbol basepoint, and text basepoint. Basepoint snap A snap you use to enter a point at the basepoint of a symbol by clicking anywhere on the entity. bearing An angle expressed in terms of points on the compass. Bearings are expressed as an east or west rotation from north or south. A standard 13°52'15" angle, for example, could be expressed as a bearing 76°07'45" east of north, or N 76°07'45" E. bevel To replace the intersection of two lines with an angled line segment. See also round. Also known as chamfer. bitmap fill Using boundary fill, you can change the appearance of a bounded area or selection set by filling it with a bitmap image. You can add new bitmap images to AutoSketch by copying them to the AutoSketch Property folder and restarting AutoSketch. boundary fill A hidden-edge polygon that displays either a solid color or hatch pattern. A boundary fill automatically takes the shape of the enclosed area to which it is applied. You can create boundary fills by using the fill tools, or by clicking and dragging a solid color or hatch pattern from the Content Librarian. break To divide an entity into two shorter entities separated by a gap of a specified width.
