How to Create a Mirror Image Part

To create a mirror image part, VTube lets you perform an Additive Invert on any column of XYZ values. This means that VTube can multiply an entire column of XYZ values negative one.

Any time the Additive Invert feature is applied an odd number of times (1, 3, 5, etc.), the part will be mirror image to the original. Any time this feature is applied an even number of times (2, 4, 6, etc.), the part will be the same shape, but with a different orientation in space.

STEP 1: Additive Invert a Column in the XYZ Coordinates

Select a cell in an XYZ column to invert, right click, the choose Additive Invert.

STEP 2: Redraw and Zoom All

If the new part does not appear on the screen, then REDRAW and ZOOM ALL.

If multiple representations of the tube are switched on (like the ALIGNED and MASTER are on here), then you will see the before and after results like this.

STEP 4: Measure The Part

This step is identical to regular reverse-engineering measuring.

Press FINISH and APPLY Measure when the measurement is completed.

STEP 5: Choose Build Measured Tube Data Only

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.

STEP 6: Copy Measured to Master

Copy Measured to Master Data in the Data Handling menu. This will overwrite the MASTER data ZEROS with the MEASURED tube data.

When you press this button, the MEASURED data will be copied to the MASTER data menu and the MASTER data menu will display automatically.

STEP 7: Optional Reset Origin to Zero

Some customers prefer to translate the new MASTER data so that the first point is at 0,0,0.

STEP 8: View the New Master Tube

View the new MASTER tube by switching the display of the Master tube on, then redrawing and zooming all.

In this case, the MASTER tube is translated in space from the measured tube because the coordinates were zeroed in the previous step.

STEP 9: Optional Alignment Test

This is a cross-check to be sure the process was performed properly. Enter the Inspection Results menu, and press Recalculate for the alignment.

Since VTube is aligning a part to itself, the deviations should be exactly zero.

STEP 10: Save the VTube Project

Press the Project Save button in the Toolbar, choose the project save path and filename, and save the VTube Project file.
