Grid and Snap
The most basic of drawing aids, Grid makes AutoCAD's canvas look like graph paper. You can adjust the grid's measured size and the spacing of its major lines to simulate many types of graph paper.
Snap constrains your ability to draw objects so that they automatically start and end precisely at grid intersections. Grid and Snap are most helpful when used together so that you can draw objects that snap to the grid. Figure 3.1 shows some of the status bar toggles that you'll be learning about in this chapter.
