Script: set object centers

[Andy]

This is a small script based on one that came with a plugin from Lisa. The original plugin was platform dependent; this version uses a script only so works on Windows, Linux and Mac. The original plugin reportedly crashed on some machines/OSs which is why this one is now available.

To install it, put the file in the "scripts" folder which is inside the AC3D folder.

It adds a tools menu item "Set Object Pivot Points" and selecting this pops up a small UI which can be used to set the X, Y, Z center (same as 'Loc' in Tools->Object-property-editor) on one or more selected objects.
