Description

Some routines such as the boolean operation of surface models are not numerically stable, which is why random changes are made to the coordinates. Nevertheless, it is not always possible to calculate a result. This is not always a problem for the design. For example, if a labelling is not engraved, then only the labelling is missing, but the mechanical function is fulfilled. However, there are cases in which a failed subtraction, for example, renders further design steps pointless. In this case, the only option is to call the function again in the hope that the numerics will then work better. Trail and error
