Constraints > Circular Array

This constraint is automatically created for a Circular array and Copy with Rotation. This constraint is indicated by the icon near center of array. Due to the constraint, the lines in the array retain the interrelations during parameterization and editing: equal angle between the elements of the array, equal radius from the center of the array. To create this constraint, the array/copy should be created in the Create copies with constraints mode.

Example

Applying Driving Dimensions to a Circular Array

Let's take a look at the circle with a rectangle is constructed along one of its axes. The center of the rectangle lies on the axis. All lines are created in the Infer constraints mode. We'll create a circular array of a rectangle. Select the rectangle with a selector frame by holding , then call the Circular array command. Check that the Create copies with constraints mode is active. Specify the number of copies equal to 4, choose the center point of the array and the angle. As soon as the array was created, a Circular array constraint was automatically created. A constraint icon has appeared on the drawing.

We put several driving dimensions on the elements of the array and change their values. Due to the Circular array constraint, all elements have changed, maintaining the equality of the geometric dimensions.
