Measuring automatically

Use this option to intelligently measure lines, arcs, and the radius of curvature on arcs, curves, and surface curves.

1. Click the Calculator button on the status bar.
2. Click the Auto-measure button.
3. Position the cursor over an object.

   If the object is a line or an arc, the intelligent cursor displays the intelligent measurement of that object. The intelligent measurements of lines and arcs are:

   • Line - length

     

   • Arc - radius

   

   • Full arc (circle) - diameter

   

   If a span of a curve or a surface curve has constant curvature, the radius of curvature is displayed when you move the cursor over the span.

   To enter that value into the calculator, click the object. The value is entered into the expressions box.

   If no intelligent measurement is associated with an object, then no value is displayed.

   When no value is displayed and you click a position on the screen, the calculator waits for you to enter a second position. As you move the cursor, a rubber-banded line is displayed from the first position to the cursor position. The length of the rubber-banded line is also displayed. When you enter the second position, the shortest distance between the points is entered into the expressions box.
