# ISOPLANE Command
[GstarCAD 2027](Help%20System/GSTARCAD/2027/Index.md) → [Commands](Help%20System/GSTARCAD/2027/Commands/(Commands).md)
**Function Description:**
This command is used to specify the current plane for 2D isometric drawing. 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 by the ELLIPSE command. Users can use "Ctrl+E" or F5 to convert the isometric planes.
