# Circular Pattern Tool

The Circular Pattern tool allows a features/geometry to be repeated in a circular pattern. In this function there is an Axial Reference and a Crown Definition where the user is able to alter the pattern.

### Axial Reference

Parametre
In this tab, the user will choose the 1 of 5 parametres to construct a circular pattern.
The 5 parametres are:

• Instance(s) and Total Angle
• Instance(s) and Angular Spacing
• Angular Spacing and Total Angle
• Complete Crown
• Instance(s) and Unequal Angular Spacing

Instance(s) and Total Angle
In this parameter mode, the program will compute the angular spacing between features after the user specified the number of instances and total angle values.

Instance(s) and Angular Spacing
In this parameter mode, the program will compute the total angle after the user specified the number of instances and the angular spacing.

Angular Spacing and Total Angle
In this parameter mode, the program will compute the number of instances the feature repeats after the user specified the angular spacing and total angle.

Complete Crown
In this parameter mode, the program will ensure a complete crown (360°) is achieved by computing the angular spacing after the user specified the number of instances.

Instance(s) and Unequal Angular Spacing
In this parameter mode, the user can define the number of instances and also the angular spacing between each features.

### Crown Definition

Parametre
In this tab, the user will choose the 1 of 3 parametres to define the crown.
The 3 parametres are:

• Circle(s) and Circle Spacing
• Circle(s) and Crown Thickness
• Circle Spacing and Crown Thickness

Before we begin explaining each of these parametres, the figure below will help you understand some of the terms used:

Circle(s) and Circle Spacing
In this parameter mode, the program will compute the crown thickness after the user specified the circle spacing and number of circles.

Circle(s) and Crown Thickness
In this parameter mode, the program will compute the circle spacing after the user specified the crown thickness and number of circles.

Circle Spacing and Crown Thickness
In this parameter mode, the program will compute the circle spacing after the user specified the crown thickness and circles.

### Instruction

To use this function, first select the feature/geometry that need to be replicated:

Next, click on the circular pattern icon. You might need to click on the black downward arrow beside rectangular pattern to find it:

Click on the Reference element textbox and then click on the plane parallel to the surface where the feature lies:

Choose the parameters and work on it. Similar to the rectangular pattern, you can disable the some of the duplicates by clicking on the dots in the preview:
