Enable computing with a sphere

In the case of a 5X sweeping realised with another tool than a ball nose mill, it is necessary to check this option to be able to activate the trimming surfaces.

The trimming surfaces allow to limit the sweeping tool path to avoid collisions. However this option can only be used if the tool is a ball nose mill. If the tool is not a ball nose mill, this option allows to take into account the trimming sufaces as if we have a ball nose mill tool (with a radius equal to the corner radius of the selected tool).It is in the 5X mode that it will be possible to turn the tool to take into account its real definition..

In the example below a barrel mill is used to do the 5x sweeping on the side with undercut, adding the blue trimming surface prevents the tool to go down into the part.

With enable computing with a sphere the trimming is still activated in 5X .

This other example illustrates how to use a side mill to do a 5x sweeping on a spherical pocket.
