Undersize
The undersize values are radius values.
Planar orbit
The undersize is applied in a XY plane (/Z diving direction of the electrode).
The software "removes the fillets", applies the undersize, then re-inserts the fillets with their first values.

Spherical orbit
The undersize is applied in all directions.
If it needed, the software removes the fillets, is for example undersize>Radius.

Undersize
value is not an associative value. z Les valeurs de sous-dimension ne
sont pas associatives. Its modification
afterward will not be put back on the geometry of the electrode.
