Changing the Grid

The circular grid is a useful tool for drawings that require points to align
along an arc or circle. However, when setting up the circular grid, it is almost
always necessary to reposition the Grid Origin so the radial lines of the grid
are aligned correctly with the drawing.
To set up the circular reference grid
1 On the Tools menu, click Drawing Options. The Drawing Options dialog
box appears.
2 Click the Grid page tab, then click the Circular page tab.
3 Enter the distance between gridpoints in the Snap Interval text boxes.
4 (optional) Check the Major as Interval check box. This check box is the
direct link between the displayed grid and the snap interval grid. When
the check box is unchecked, you must enter the number of snap intervals
between major lines. When the check box is checked, you must enter the
interval between major lines.
5 (optional) Enter the number of snap intervals between major lines in the
Major Frequency text box.
6 (optional) Enter the distance between major lines in the Major Interval
text box.
7 Select a style from the Minor Style drop-down list box.
■
None removes the minor lines from the reference grid.
■
Subdivisions creates a pattern of minor lines, equally spaced between
major lines.
■
Offset creates one minor line, offset a specific distance from the major
line.
■
Double Offset creates minor lines offset a specific distance on both
sides of each major line.
8 (optional) Click a number of subdivisions between major lines in the
Minor Subdivisions drop-down list box.
9 (optional) Enter an offset distance between the minor and major lines in
the Minor Offset distance text box.
10 (optional) In the Grid Position section, enter new coordinates in the
Origin text boxes. The first text box is the x-coordinate, the second is the
y-coordinate.
11 (optional) Enter a new angle in the Angle text box.
12 Click OK.
