If necessary

The user can allow a collision avoidance by clicking on this button.  In that case, the user does not have to worry about collisions between the tool, the part as well as the machine’s environment.

This is because TopSolid'Cam will automatically clear the tool to a height defined by the user if it's necessary.

In this case, the button "clearance plane" is disabled.
