Hi guys,
I had time to update this just released script requested by oXYnary.

IC.SizeInScreen calculates the apparent dimension measured in pixels of the current
selection in Screen Coordinate System. Works on Editable Polys and Meshes. Has the ability to set current view to the right zoom factor to achieve the needed dims, and other nice features.

It is quite a particular task, oXYnary stated it helps when dealing with TGEA engine. Well, it was just fun to code, I hope you like it

As usual, get it form the IllusionCatalyst website, in MaxScript page, under Scripts.

Wow. Its even better now. Awesome work Synchview. I put a post up at the Garage Game forums letting people know about this plugin.
