When the machine has a transmit function (e.g. G12.1), rather than sending a path decomposed on the axis of rotation (many points), we can use this box to ask TopSolid to send the XY path to the machine. It is then the transmit function of the machine that will wrap the tool path.
We can then have a simpler tool path (with arcs for example) as well as the use of compensation (G41/G42).
It is therefore only possible to use this option if the machine tool controller has a TRANSMIT function (G12.1 for example.
Attention: do not check the transmit box for drilling.
