Applying Tolerances to a Single Feature The process of applying tolerances to features is nearly identical for all feature types, only the tolerance type and the entry of nominal values are different. The four methods of entering nominal values and applying tolerances include: • Enter nominal values using keypad • Auto round actual values • Enter values with keypad or auto round and then use place tolerancing • Import nominal values from a DXF drawing file (CNC enabled systems) The four methods are diagrammed here. The differences between these methods are shown in shaded blocks. The contents of each block will be explained in detail. The blocks that are common to all processes will be explained as part of an example of tolerancing a circle. The blocks that are unique in each process will be explained separately.
