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.

The following prompts are displayed.

Left

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

Top

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

Right

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