 The '''Intersection Pass Distance''' shows how near each intersecting 3D centerline comes to each other in 3D space. If the Nearest Pass value is more than the Nearest Pass Tolerance, then VTube-LASER will warn you. This is active for both LASER scanner and ball probe. See [[VTube-LASER Nearest Pass]] for an illustration.

 As mentioned above, because the DCF engine creates two cylinders, it always builds and compares the resulting intersection points from both cylinders. It warns you if they don't match well enough.<br><br>

 The '''Maximum Wobble''' value predicts how precise the surface data fits the cylinder. This was in previous versions, but now two cylinders must pass - not just one.  And we've created a single new value to display at the top rather than multiple XY values.<br><br>

-When using the laser scanner in Uniscan mode, VTube cylinders must pass a total of FOUR checks to be qualified as good cylinder scans.<br><br>(Versions before 2.8 only required CHECK 1 shown below. This 4-level check is only available in version 2.8 and newer.)
