      <p class="para_topic"> You can define a coordinate system by specifying its origin and two other points that determine its X and Y axes. The system prompts you to select points 1, 2 and 3 using the Point Constructor.</p>
      <div class="title_division"> Point Selection Order</div>
      <p class="para_division"> The first point that you select becomes the origin of the coordinate system. The second point lies on the X axis of the coordinate system. The positive X direction is from the first point (origin) toward the second point. The third point determines the positive direction of the Y axis. The three points must not be collinear.</p>
      <p class="para_division"> For example, in the figure, point 1 defines the origin, point 2 lies on the X axis, and point 3 determines the positive Y axis direction.</p>
      <p class="para_division"> After you select the three points, the system exits the CSYS Constructor.</p>
