 This is the size of the voxel grid that will be used to search for neighbors. The smaller the value, the more accurate the algorithm will be but the slower it will be.

+The command will substract a cloud from another cloud. The command will output a cloud that is the result of the substraction of the two input clouds. The clouds can have a different number of points. Select first a *cutter* cloud and then a *to be cut* cloud. The *cutter* cloud will do a radius search for each of its points on the other *to be cut* cloud. If the distance between the two points is smaller than the `RadiusSearch` value, the point will be removed from the *to be cut* cloud.

+**Command options:**

+RadiusSearch=0.003
+```
+{: .fs-6 .fw-300 }
+The radius of the search for each point of the *cutter* cloud. The bigger the value the more rough the substraction will be.
