Selecting and Deselecting There are several ways to select objects in AutoCAD Civil 3D: ■ To select an object, click it in the drawing window. ■ To select an individual object that is part of a group of objects, press and hold Ctrl while clicking the object. ■ To select several objects by enclosing them within a rectangular area, drag your cursor from left to right. A rectangle with a solid line appears. Only objects that are enclosed in the rectangular area are selected. ■ To select several objects by crossing over them with a rectangular area, drag your cursor from right to left. A rectangle with a dashed line appears. Any objects that the dashed line crosses over are selected. If you select the wrong object, press Esc to deselect it. Experiment with the selection methods using the objects in drawing Intro-2.dwg. Object Snapping This standard AutoCAD feature is useful for precision drafting, when you want the line you are drawing to snap to entity edges or specific points. In these tutorials, you may prefer to use a freehand mode for drawing and editing objects, such as horizontal alignments and layout profiles. Object snaps, also known as OSNAPs, can be used in either of two ways: ■ Individual, or single-point OSNAPs- To snap to a specific type of point, hold the Shift key down and right-click. Select an object snap from the shortcut menu. The object snap stays in effect only for the next point that you click. ■ Multiple, or running OSNAPs-You can toggle Object Snap on and off by clicking on the status bar at the bottom of the main application window, or by pressing F3 or Ctrl+F. Object Snap is off when the button is in a raised position. 16 | Chapter 2 Getting Started Tutorials
