Measure radius
You can measure the radius of several objects. You can measure:
partial and full cylinders
fillet
circle
arc
major radius of both partial and full torus
minor radius of both partial and full torus
In this section:
Measuring the radius of a cylinder, arc, or circle
Measuring the major radius of a torus
Measuring the minor radius of a torus
To measure the radius of a cylinder, arc, or circle
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. Specify the cylindrical face, circle, or arc. The viewer displays the radius in the Distance Output box.
4. You can click further measure options, or click to complete the operation.
To measure the major radius of a torus
You can measure the major radius of both partial and full tori.
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. Click a face on the torus.
4. Click Torus Major. The viewer displays the radius in the Distance Output box.
5. You can click further measure options, or click to complete the operation.
To measure the minor radius of a torus
You can measure the minor radius of both partial and full tori.
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. Click a face on the torus.
4. Click Torus Minor. The viewer displays the radius in the Distance Output box.
5. You can click further measure options, or click to complete the operation.
