Obtain a Point by Cursor
To enter a point using the pointing device, use the cur function. The program
prompts you to specify a point and uses the coordinate values of the point in
the expression. The point coordinate values are expressed in terms of the
current UCS. The cur function sets the value of the
LASTPOINT (page 1344)
system variable.
The following example adds the vector [3.6,2.4,0]—the result of 1.2*[3,2]—to
the point you select. This expression produces a point that is offset from the
selected point.
cur+1.2*[3,2]

Obtain the Last-Specified Point
Use the character in the expression to obtain the coordinate of the last point,
as shown in the following example:
Command: line
Specify first point: 'cal
>> Expression: cen+[0,1]
>> Select entity for CEN snap: Select a circle or an arc
Specify next point or [Close/Undo]: 'cal
>> Expression: +3*vec1(cen,cen)
The first point of the line is 1 unit in the Y direction from the center of the
first selected circle. The second point of the line is 3 units away from the first
point. The direction of the line is from the center of the first selected circle
to the center of the second selected circle.
