How the XYZ Intersection Tolerances Work

The XYZ intersection tolerances allow you to quickly qualify a part using +/- tolerances to the intersection points.

The intersection tolerances are based on values are that follow the three axes in a coordinate system. Since the tolerances measure along the axes, as of version 1.93, these tolerances can be positive or negative to also indicate a direction.

XYZ Intersection Deviations

The XYZ intersection tolerances are based on the XYZ deviations as shown in the model in this screen image.

In this case, most of the error is in the Y axis. It can be verified by seeing that the intersection point of the derived data is visually above the master point. (You can click on the image to make it larger.) The deviation data indicates that it is exactly 0.012" above the master point in the Y axis.

The reason the grid is entirely green is because the tolerance values are higher than the deviation values (in this case the tolerances are 0.039").

Note: The 0.013" value is the 3D deviation from point to point. Unless it lays on an X, Y, or Z axis, it is usually slightly larger than any of the other values.

Set the Default Tolerance in Part Setup Menu

You can set the default tolerance in the Part Setup menu. Scroll down to row 34.

Set the Default Tolerance in General Setup Menu

You can set the default tolerance in the Inspection Data General Setup menu.

Set the Default Tolerance in Inspection Data Menu

You can set the default tolerance in the Inspection Data menu by entering a Default Tolerance at the top and pressing the Set button.

Set the Tolerances in Inspection Data Grids

Click on the Change Grid Setup button until you see the tolerances in the grid like we show in the image on the right.

Then select and change any tolerance value. The grid will allow you to edit only the tolerances.

Set the Tolerances in Expanded Windows

The second place to edit the value is in the VTube-LASER Expanded Window.

Click on the Expanded Window button to display the Expanded Window, and then make changes to the tolerances there.

The benefit of the Expanded Window is that you can view all the tolerances at the same time.

(You can click on the image to see it larger.)

Setting All The Tolerances At The Same Time

The intersection deviation grids allow you to set the default tolerance to every value in a row, column, or even the entire grid using a popup menu

To use this feature, single click on a tolerance value, then right click and choose the action in the popup menu.
