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 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]
