== How to Create a Mirror Image Part - Additive Invert a Column in an XYZ Grid ==
<table cellpadding=10 width="900">
<tr valign=top>
<td width=500 >
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.<br><br>
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===
<table cellpadding=10 width="900">
<tr valign=top>
<td width=400 >
Select a cell in an XYZ column to invert, right click, the choose Additive Invert.

===STEP 2: Redraw and Zoom All===
<table cellpadding=10 width="900">
<tr valign=top>
<td width=400 >
If the new part does not appear on the screen, then REDRAW and ZOOM ALL.<br><br>
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.

== How to Create a Mirror Image Part - Swap Any Two Columns in an XYZ Grid ==
<table cellpadding=10 width="900">
<tr valign=top>
<td width=500 >
VTube also lets you perform column swaps. This means that VTube can swap the XY, XZ, or YZ columns in an XYZ grid.<br><br>
Any time you swap columns an odd number of times (1, 3, 5, etc.), the part will be mirrored 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 2: Redraw, Zoom All, and Alignment===
<table cellpadding=10 width="900">
<tr valign=top>
<td width=400 >
If the new part does not appear on the screen, then REDRAW and ZOOM ALL.<br><br>
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 after you perform an alignment.
