Circle points

On this page, you can automatically create points that can be used to define circular or elliptical surfaces.

Types of circles

You can choose from three basic types:

Simple

• A full circle can be defined with 6 points. These are the points of 2 Bézier curves.
  
  
• This method is not very precise, but it uses half the points and curves compared to the normal method.
  
  
• It is commonly used for relatively small sizes (buttons, etc.).

Normal

• A full circle can be defined with 12 points. These are the points of 4 Bézier curves.
  
  
• This method allows you to draw a precise circle or ellipse. (The distance of the Bézier control points is always 55% of the radius.)

Segmented

• The points will be on the line of the circle or ellipse.
  
  
• In this case, the circle is approximated with straight segments.
  
  
• You can specify the number of segments in a quarter circle.

Circle size and position

Size

• Here you can specify the radii of the circle or ellipse. Naturally, there is only one for a circle.
  
  
• You can toggle which quarter section you want.
  
  
• This cannot be set for the simple type.

Position

• You can choose which coordinate plane the circle should be parallel to.
  
  
• If you want it tilted differently, you can rotate the completed circle as desired on the surface movements page.

Creating circle points

• Select an existing point that will be the center of the circle.
  
  
• After setting the above parameters, press the "New Circle Points" button.

• The new circle points will be directly connected to the center point.
  
  
• When moving, you will only need to move the center point.
  
  
• Circle points can also be individually moved from their positions.
