Without the Cut Plane Offset set properly, scanning data from a cylinder on a table would appear like this to VTube-LASER.

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.

STEP 2

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

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.

STEP 4

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

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.)

Offset Distance Rule

1. VTube can work with offsets that are up to about half the diameter of a tube.
   
   
2. This would mean that small diameter tubes that are less than 0.25" diameter might not scan well on a regular office table.
