Using isometric snap and grid

You can use the isometric snap and grid option to create two-dimensional isometric drawings. With the isometric option, you are simply drawing a simulated three-dimensional view on a two-dimensional plane, much the same as you might draw on a piece of paper. Do not confuse isometric drawings with three-dimensional drawings. You create three-dimensional drawings in three-dimensional space.

The isometric option always uses three preset planes, which are denoted as left, right, and top. You cannot alter the arrangement of these planes. If the snap angle is 0, the three isometric axes are 30 degrees, 90 degrees, and 150 degrees.

When you check the Isometric Snap and Grid option and select an isometric plane, the snap intervals, grid, and crosshairs align with the current plane. The grid is always shown as isometric and uses y-coordinates to calculate the grid spacing. If you select the Draw Orthogonal check box, the program restricts the drawing of entities to the current isometric plane.


TIP To toggle between isometric planes, press F5.


To turn the isometric snap and grid option on

  1. Do one of the following:
    • Choose Settings > Drawing Settings.
    • On the Settings toolbar, click the Drawing Settings tool ().
    • Type settings and then press Enter.
  2. Click the Coordinate Input tab.
  3. Under Change Settings For, select Snap And Grid.
  4. Click to select the Isometric Snap And Grid check box.
  5. Under Isometric Crosshairs, click the option for the isometric plane you want (left, right, or top).
  6. Click OK.
