from the Grid edit bar. If your drawing requires you to switch grid types often, you can also use the Grid toolbar to change the grid type or to double or halve the size of the grid. Another way to use onscreen drawing aids is to place guidelines in the drawing. Guidelines consist of lines or circles that you place in the drawing in order to increase precision. Both Gridpoint snap and Snap Off mode automatically snap points to guidelines. Like the reference grid, guidelines do not actually appear on printed output. However, unlike the reference grid, you can draw guidelines anywhere you like, allowing more flexibility than the reference grid. Changing the Grid You may have projects or preferences that require you to change AutoSketch's grid default settings to meet specific requirements. If so, you can easily adjust the grid snap interval, as well as the frequency and position of major and minor grid lines, to increase or decrease the grid's density. You can even change the grid origin and angle if you need to align your drawing to a known point or angle. Changes to the grid settings are performed on the Grid page of the Drawing Options dialog box. Changes to the default color or style of lines, dots, and the Drawing Origin are made on the Appearance page of the View Options dialog box. Setting Up the Grid The grid snap interval-the distance between the points on the reference grid-affects a drawing anytime you are using Gridpoint snap. When you use Gridpoint snap, the coordinates of all points you enter are rounded to a multiple of the snap interval. Normally, the horizontal and vertical settings for the grid are the same, but they can be specified individually. The lines and dots of the grid provide a visual reference only. The lines of the reference grid are separated into two categories: major and minor. AutoSketch allows you to customize the appearance of the reference grid by selecting color and pen style for major and minor lines. By default, the grid origin of the default reference grid is located at the drawing origin, which, in turn, is located in the lower left corner of the page, with the x-axis extended at 0 degrees and the y-axis extended at 90 degrees. However, if you need to align an entity, you can change the grid origin position, which is normally set to 0,0. Likewise, if you need to draw along a Changing the Grid | 61
