 This function can be used to calculate the appropriate number of segments based on the radius of the rounded shape. This function can be used to calculate the appropriate number of segments based on the radius of the rounded shape.
  
-//NOTE: The number of segments can become large depending on the 'precision' requirements. Testing designs with a lower number of segments is recommended.//+Using the above example, the arc has a radius of 3.5 mm (units are typically mm). The laser printer requires 0.1 mm segments or more while moving. The segments can be calculated, and supplied when creating the arc.
