There are several calculation strategies available in WinWerth® for analyzing circles and cylinders. Among others, Gaussian, maximum inscribed, minimum circumscribed, and minimal zone elements can be calculated. Expanding on the maximum inscribed, minimum circumscribed, and minimal zone elements can be calculated. Expanding on the maximum inscribed conditions, the two point dimension has been introduced. For the maximum inscribed circles, the least diameter, and for minimum circumscribed circles, the greatest diameter is output. The new “contact Plane” calculation strategy makes it possible to determine co-planarity of integrated circuit (IC) leads, for example. Coplanarity is a critical dimension for manufacturing these parts, because the distance between the IC leads and the circuit board influences the soldering process. Ensuring the leads are within the prescribed distance from the board is the only way to solder reliably. The measurement can be performed using autofocus points or the Chromatic Focus Line Sensor and calculating a plane from the extreme points. The form error is the distance between shortest lead and the contact plane. In addition, the software has been expanded to include the penetration point of a line through a torus. The penetration point is used to obtain the position of a prescribed diameter on the torus. From this position the distance to a plane can be calculated.
