A new preview feature has been added which allows the clearance height, retract height, feed height, stock height, and depth to be visualized when editing a 3D operation. The currently selected tool will also be shown such that the tip touches the previewed plane.
To visualize a specific linking parameter, click on the corresponding field on the operation property page. If no parameter is selected the clearance plane is visualized. The plane dimensions are derived from the bounding box of the selected geometry.
