Foton mould solves the following problems by using CADdoctor:

1. The number of procedures is difficult to deal with (digital-to-analog suture), so it needs to be done by the designer in the early stage

2. The mathematical model cannot be cut out, so it needs to be repaired or broken into small parts

3. Parameters are reserved in the initial stage of design, and most of them will affect the update speed if they are processed after the review is completed. The operation sequence of some features has an impact on the adjustment range of parameter values, and some of the correlations are in the later stage
