To measure radii
You can measure the radius of a cylinder, fillet, circle, or arc. You can measure the radius of both partial and full cylinders. You can also measure the major or minor radius of both partial and full tori.
To measure radii,
1. Click Analysis and then, in the Measure group, click the arrow next to Rad/Dia.
2. Click Radius. The Measure Output and Distance dialog boxes open.
3. Creo Elements/Direct Modeling displays the radius in the Distance Output field.
a. If you want to measure the radius of a cylinder, fillet, circle, or arc: select the cylindrical face, circle, or arc.
b. If you want to measure the major or minor radius of a torus: click a face on the torus. Click Torus Major or Torus Minor.
4. Click the green arrow button to send the measurement to a command.
5. Click the green arrow and calculator button to send the measurement to the calculator.
To measure the radius of a blended edge,
1. Click Analysis and then, in the Measure group, click Blend/Chamfer. The Measure Output and Blend/Chamfer dialog boxes open.
2. Select the blended edge you want to measure.
3. Creo Elements/Direct Modeling states whether the blend is of a constant or variable radius, and displays the radius of the blend in the Blend/Chamfer field. If you have measured a blend of variable radius, graphical feedback is provided to show the radius at the beginning and end of the blend.
4. Click the green arrow button to send the measurement to a command.
5. Click the green arrow and calculator button to send the measurement to the calculator.
