• Back to VTube-LASER

The Split Bend feature allows you to accurately measure bends that equal or exceed 180 degrees.

Split Bend setup is controlled in the Bend Setup tab of the Master Tube menu in VTube-LASER, and in the Bend Setup tab in VTube-STEP. Both modes of VTube allow you to configure Split Bends.

To turn a Split Bend ON for a straight section, you enter the Split Bend window and select the straights that should be treated as Split Bends.

Enter the Part Setup data for the new part. Especially enter the DEFAULT RADIUS. (You can measure the radius if necessary in Measure Process.)

Since the Split Bend feature creates a grid based on the number of straights in the MASTER data, it is important to set the number of points that you will be measuring in the reversed tube.

Enter the MASTER TUBE menu, set the point count (which is two more than bend count), and press the SET button. The XYZ values will be filled with zeros like this:

The radius values were automatically filled with the DEFAULT RADIUS value from the PART SETUP menu.

The Split Bend window is on the Bend Setup tab in the MASTER TUBE menu. Click into that window.

In the Split Bend window, set any straight that will be treated as a Split Bend.

Close the window. VTube will now understand which straight to treat as a Split Bend during measuring.

This step is identical to regular reverse-engineering measuring.

Press FINISH and APPLY Measure when the measurement is completed.

Because the MASTER data row count is greater than zero, the Measurement Complete window will offer to allow you to ALIGN the measured tube.

However, do NOT align at this point - because there are only ZEROS in the MASTER Data fields.

Rather - press the Build Measured Tube button.

The new measured tube will appear as a blue tube like this.
