Method to select resolution values

A method for selecting resolution values for a computer aided design model, the method comprising:

• determining a set of geometric relationships in relation to a set of object representations within the computer aided design model, wherein each geometric relationship of the set of geometric relationships is represented by a number;
• determining a set of intervals within the set of geometric relationships that meet a resolution interval criterion, wherein each interval of the set of intervals is a numerical range that does not include numbers representing the set of geometric relationships;
• selecting a set of resolution values, wherein each resolution value of the set of resolution values is within one of the intervals according to a resolution setting criterion;
• updating the computer aided design model, the updating of the computer aided design model comprising implementing the set of resolution values;
• generating a set of instructions for controlling a manufacturing process using the updated computer aided design model;
• and
• outputting the set of instructions to a manufacturing system for the manufacturing system to control the manufacturing process according to the set of instructions,
• wherein an interval meets the resolution interval criterion when the interval accommodates a sub-interval,
• wherein a lower limit of the sub-interval is equal to a lower limit of the interval multiplied by a sub-interval factor, such that the lower limit of the sub-interval is the sub-interval factor times larger than the lower limit of the interval,
• wherein an upper limit of the sub-interval is equal to an upper limit of the interval divided by the sub-interval factor, such that the upper limit of the sub-interval is the sub-interval factor times smaller than the upper limit of the interval, and
• wherein the resolution setting criterion is meetable when the resolution value is within the sub-interval corresponding to the interval within which the resolution value is set.
