About the Circle Command

It is possible to create a circle manually.

To create a circle manually, move the pointer to activate SmartPick and click as soon as you get the required option.

Changing the Circle Radius

Once you have created a circle, you can change its radius.

To change the radius of the circle, you can perform either of the following actions:

  • If the offset constraint corresponding to the radius exists: Double-click the offset constraint and modify the radius value in the Constraint Definition dialog box that appears.
  • Double-click the circle and modify the radius value in the Circle.1 dialog box that appears.
  • Drag the circle until you get the required radius.

Circle Center

By default, circle centers are visible in the geometry.

If you create circles by clicking and do not want to see the centers, you can specify your preference in the Preferences dialog box. For this, clear the Create circle and ellipse centers check box under Me > Preferences > App Preferences > 3D Modeling > 3D Modeling Core , under tab.

Tip: If the circle center is fixed (or iso-constrained), you can change the circle radius using one of the methods explained above.

If you select a circle, an ellipse, an arc of a circle or an arc of an ellipse in a sketch, its center point is automatically highlighted, provided the Create circle and ellipse centers check box is selected. This helps to differentiate the center point of the selected geometry from the other points in the sketch. It is also applicable when you select multiple geometry objects such as several circles, arcs or ellipses in the graphic window or in the tree. However, in case of geometries created without their center points there is no visual change (i.e. there is no highlight).
