In Ortho mode, cursor movement is constrained to the horizontal or vertical directions (relative to the UCS) and with the current grid rotation angle.
In the example, a line is drawn using Ortho mode. Point 1 is the first point specified, and point 2 is the position of the cursor when the second point is specified.
AutoCAD LT uses Ortho mode when you specify an angle or distance with a pointing device, but Ortho mode does not affect keyboard point entry. AutoCAD LT ignores Ortho mode in perspective views.
AutoCAD LT defines horizontal as parallel to the X axis of the UCS and vertical as parallel to the UCS Y axis. Changing snap rotation adds an additional rotation with respect to the UCS.
Commands:
DDRMODES sets Ortho mode on or off using the Drawing Aids
dialog box. SNAP aligns points entered by a pointing device.
POLAR constrains cursor input to specified angles and radial distances
UCS manages user coordinate systems.
System Variables:
ORTHOMODE stores the Ortho mode setting.
