 Note
Fast calculation will be automatically executed if no effective burn-area value available (=0) so far. Fast calculation will
be good enough for most electrodes with only one shape as it uses all surfaces below FREE FACE. It’s results are limited if additional features — especially supporting geometry are added:  Also a combination of shapes machining in different positions is not suitable for fast calculation.
