Part Setup Menu

You can calculate the cut length of the tube in the Part Setup menu in either STEP or LASER modes.

To calculate the cut length, right click on the Part Setup menu, and choose "Calculate Cut Length".

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 Tolerances in Inspection Data Menu

You can set these tolerances in two places in VTube-LASER. The first place is in the Inspection Data menu.

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.

Or 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.

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.

The screen images on the right show an example of before and after changes made to an entire column:

XYZ Intersection +/- Tolerance Values in Printed Reports

The XYZ Intersection deviation values can be included in reports:

  1. plus tolerance values
  2. minus tolerance values
  3. out of tolerance values

The first Inspection Report in the reports menu is good for showing this data.
