TP_OFFSET_Z
It creates, to the left or to the right side of the selected polyline, the tool radius compensation path. The final depth of the output path can be achieved in one or more  Z movements. Inputs and outputs can be added to the final path.
TP_OFFSET_XY
It creates, to the left or to the right side of the selected polyline, the tool radius compensation path. The path can be constructed by a variable number of approaching movements in the plane of the selected polyline.
TP_POCKET
It  creates, from a selected closed polyline, the tool centre point path that empties the area inscribed in the polyline. The final route includes a boundary movement and internal routes with three possible ways; linear, zigzag or concentric. In the area you can insert islands that are respected and not emptied.
