About Cut Planes

Cut planes allow VTube-LASER to define a plane of a table or other surface in order to cut laser points from being used in measurements to VTube-LASER.


How to Create a Cut Plane

Cut planes are created with four measurements with the ball probe.

STEP 1

In VTube-LASER click on Measure Process, then click on Measure Cut Plane. The Laser scanner will turn off automatically.

Follow the instructions in the yellow guide box on the left.

Touch the table with the ball probe and press and release the green button.

STEP 2

Move the probe to another place on table. The further away from the first point, the better for the math engine.

Press and release the green button.

STEP 3

Move the probe to another place on table in a way that forms an approximate equilateral triangle. (It is best to not make the triangle a thin sliver triangle.

Press and release the green button.

STEP 4

Move the probe anywhere above the table. This forms the up direction of the plane (also called the "normal" to the plane)

Press and release the green button.

STEP 5

The Cut Plane Offset menu will display.

Enter the cut plane offset in this window. There must be an offset or table points will eventually be included in the scan.

Granite Surface Plate

0.039" offset is acceptable

Office Tables

0.125" offset is usually acceptable (Tables are much less flat than surface plates - so the offset needs to be greater than on surface plates.)

General Offset Rule

VTube can work with offsets that are up to about half the diameter of a tube.

This would mean that small diameter tubes that are less than 0.25" diameter might not scan well on a regular office table.

STEP 4

Press the Close button in the FARO Arm Utilities window.

STEP 5

Observe that the new ball probe selection will appear in the Arm grid.
