CAN VTUBE-LASER CALCULATE TRUE POSITION?

The answer is YES - VTube-LASER has spherical radius true position values in it - which is what the quality control needs when required to use GD&T along the centerline of the part.

Here is how we can interpret the values in relation to GD&T:

Tangent Point Deviations: Spherical Radius True Position

The tangent point deviations along the centerline Spherical RADIUS True Position values.  This is a grid of those values (Tangent-Midpoint-Tangent along each straight).

This shows emphasis given to the middle straight.

Values

The T1 and T2 TRANSLATE values control the influence that tangent 1 or tangent 2 have in each straight. This is a translation influence - which means it controls the influence along the X, Y, and Z axes without reference to any twisting motion for the alignment.

The STRAIGHT VECTOR values allow each straight to have more or less influence with rotational or angular alignment - like a twist. (Twist in alignment is also referred to as "transformation" - which is distinct from "translation". See the T1 and T2 TRANSLATE for "translation.)

Set these values to change the alignment. Then press recalculate alignment.

Popup Menu

As of 2.9.17, VTube also includes a popup menu to make changing the values easier.
