To edit properties of the measure tool

The view tab

  • The Measurement section lets you know the distance between the start-point and the end-point and the angle. The perimeter and area measurement are active only when you are using Perimeter or Area tool.

  • The Cursor Location section shows the X and Y coordinates of your cursor in relation to the start-point. Your start-point is set as X=0, Y=0.

 

The settings tab

  • Perpendicular Measurement. Check to set measurement lines always at right angles.

  • Caption Style (Distance tool only). Specify whether the distance measurement caption is placed Inside or on Top of the measurement line.

  • Units Settings. Set to change the scaling ratio and unit of measurement on the drawing areas. Enter the scale ratio in the Ratio text field.

  • Snap Settings. Check Snap to 2D to have the measurement points snap to points, edges, or arcs in the document.

    • Check Snap to Path to enable snapping the measurement to the end of a line.

    • Check Snap to Path Endpoints to snap the measurement to the endpoint of a line.

    • Change Snap color to decide the color of the square that appears when you move the pointer to a line.

    • Set Sensitivity to define how close the pointer must be to the items being snapped to.

 

The markup tab

  • Use Markup. It turns measurements into comments. The text you enter in the Use Markup text field will become note comments in the Measurement pop-up notes and also in the Comment panel.

  • Measuring Color. Set the color of the measurement lines.

  • Set Length as Default (Distance Tool only). If selected, you don’t have to manually move the cursor to determine the leader length each time you make a distance measurement.

  • Length (Distance Tool only). It specifies the length of the line leader that appears on one side of the measurement points.

  • Extension (Distance Tool only). It specifies the length of the leader extension that appears above the measurement line.

  • Offset (Distance Tool only). It specifies the amount of blank space that appears between the measurement points and the leader.
