ISOPLANE (Command)

Specifies the current plane for 2D isometric drawing.

Note: The ISOPLANE command has been superseded by the ISODRAFT command. The primary advantage of ISODRAFT is that when it is turned is turned on or off, all related settings are automatically changed as well.

ISOPLANE involves the following settings and modes when drawing 2D isometric representations of 3D models:

  • Ortho directions
  • Snap orientation
  • Grid orientation and style (dotted)
  • Polar tracking angles
  • Orientation of isometric circles

The isometric plane affects the cursor movement only when the snap style is set to Isometric in the Drafting Settings dialog box, regardless of whether snap is turned on. If the snap style is Isometric, Ortho mode uses the appropriate axis pair from 30, 90, and 150 degrees.

The current isometric plane also determines the orientation of isometric circles created with the Isocircle option of the ELLIPSE command.

Tip: You can quickly cycle through the isometric planes by pressing Ctrl+E or F5.

The following prompts are displayed.


Specifies creating left-facing planes, defined by the 90-degree and 150-degree axis pair.


Specifies creating top-facing planes, defined by the 30-degree and 150-degree axis pair.


Specifies creating right-facing planes, defined by the 90-degree and 30-degree axis pair.
