Customizing the Grid, rectangular, Circular, Isometric

Page 70 highlights

AutoSketch's reference grid is an onscreen drawing aid consisting of a snap grid and a pattern of lines, crosses, or dots which represent the grid visually. You can use the reference grid as a visual aid for drawing, or you can increase the precision and uniformity of the points you enter by using Gridpoint snap to automatically snaps points you enter to the grid. There are three types of reference grids available in AutoSketch, each suited for different purposes. s The default grid is rectangular, with snap intervals and lines that parallel the x- and y-axes. This grid is the standard reference tool for most twodimensional drawings. s Circular grids extend radially from the grid origin. They provide an excellent reference tool for drawings that require alignment of points along an arc or circle, such as a mechanical drawing of a gear. s Isometric grids align along three major axes, instead of two. This allows you to create two-dimensional drawings of three-dimensional objects. Because perspective is not applied, the objects can be accurately dimensioned. AutoSketch allows you to modify the settings for each of the reference grids. For each type of grid, controls on the Grid page of the Drawing Options dialog box allow you to change the default origin, angle, grid snap interval, and so on. Likewise, controls on the Appearance page of the View Options dialog box allow you to change the default color and appearance of the grid's lines and dots. You can also change the grid type, angle, origin, and so on, 60 | Chapter 6 Customizing the Grid

Chapter 6
Customizing the Grid
AutoSketch’s reference grid is an onscreen drawing aid consisting of a snap
grid and a pattern of lines, crosses, or dots which represent the grid visually.
You can use the reference grid as a visual aid for drawing, or you can increase
the precision and uniformity of the points you enter by using Gridpoint snap
to automatically snaps points you enter to the grid. There are three types of
reference grids available in AutoSketch, each suited for different purposes.
The default grid is
rectangular
, with snap intervals and lines that parallel
the x- and y-axes. This grid is the standard reference tool for most two-
dimensional drawings.
Circular
grids extend radially from the grid origin. They provide an excel-
lent reference tool for drawings that require alignment of points along an
arc or circle, such as a mechanical drawing of a gear.
Isometric
grids align along three major axes, instead of two. This allows
you to create two-dimensional drawings of three-dimensional objects.
Because perspective is not applied, the objects can be accurately
dimensioned.
AutoSketch allows you to modify the settings for each of the reference grids.
For each type of grid, controls on the Grid page of the Drawing Options
dialog box allow you to change the default origin, angle, grid snap interval,
and so on. Likewise, controls on the Appearance page of the View Options
dialog box allow you to change the default color and appearance of the grid’s
lines and dots. You can also change the grid type, angle, origin, and so on,
