Chapter 6 Customizing the Grid
There are three isometric grid types to choose from—each offering a different
drawing plane for the snap grid. Isometric Top aligns the snap and line grids
along 30- and 150- degree axes. Isometric Left aligns the grids along 90- and
150- degree axes. And Isometric Right aligns the grids along 90- and 30- degree
axes. When drawing a 3D model, you can use the Isometric grids to draw on
a top, left, or right plane.
To set up the isometric reference grid
1 On the Tools menu, click Drawing Options. The Drawing Options dialog
box appears.
2 Click the Grid page tab, then click an Isometric page tab.

unchecked, you must enter both horizontal and vertical values in each of
the following steps.

5 (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.

Major Frequency text box.
