2 Use an object snap to specify a point on an object that is not on the XY
plane of the UCS.
This location defines the first point of the line.
3 Enter .xy and then enter @ at the Of prompt.
This operation extracts the X and Y coordinate values from the first point.
4 Enter 0 to specify the Z value.
The X and Y values extracted from the first point are combined with a
new Z value (0) to finish the definition of the second point.
5 Press Enter to end the command.
Quick Reference
Commands
UCS
Manages user coordinate systems.
System Variables
ELEVATION
Stores the current elevation of new objects relative to the current UCS.
FACETRES
ISOLINES
Specifies the number of contour lines per surface on objects.
Add 3D Thickness to Objects
Use the thickness property to give objects a 3D appearance.
The 3D thickness of an object is the distance that object is extended, or
thickened, above or below its location in space. Positive thickness extrudes
upward in the positive Z direction; negative thickness extrudes downward
(negative Z). Zero (0) thickness means that there is no 3D thickening of the
object.
