This is a modification which allows you to use product options to modify it's dimensions, just as you would with price, points or weight. You can modify the dimensions based on addition (+), subtraction (-), multiplication (*), or equal to (=).
You will find this a useful companion to any shipping modules which use product dimensions to get rate quotes, such as Qphoria's UPS Deluxe addon.
NOTE: For OpenCart 3.0 and up: The extension is packaged as a standard OCMOD which can be installed via admin extension installer. NOTE: For OpenCart 2.3 and earlier: You must install vQmod for this to work. You can get the latest release here: vQmod on Github
