Whats up with this volume plugin? Ive downloaded the 20kb ish one, the newer version i guess, but i cant find any menu or anything to get it to work.

There never was a menu. Select a some things (groups/compos) and right-click context-menu to get Volume option and it runs...

Does it have to be a group or component? Thats about the only thing I havent tried thus far. And i realize it is a context menu (meaning right click) I guess so. Damn, thanks much and now that it works its rather nice lol.
EDIT**
Ok it might be a stupid question but how accurate is this plugin on oddly shaped/curved enclosures?
Im hoping it is VERY close because if it is that means that what I designed is perfectly the right size to a tenth of a cubic foot on the first try. -

I'm hoping it is VERY close because if it is that means that what I designed is perfectly the right size to a tenth of a cubic foot on the first try.The earler version has % accuracy options - this was because accuracy=time-taken-to-work-it-out... However the current version is as accuraate as SUp/Ruby can be... BUT it is more unforgiving if shapes aren't 'manifold' - I am working on an update, BUT for now to be 100% sure that the returned result is 'accurate' you should make sure that the object(s) in question has/have all sides 'faced' and it is/they are 'manifold' - i.e. there are no loose face planes hanging about...
To compare them find and downlaod v1 and v2 and then try both... v1 might take ages to calculate BUT it has confirmed 'accuracy': v2 is as accuracte as it can be BUT it can fail if geometry is not as expected... -
Well the geometry is closed and all the faces are in the same direction if thats what you mean by "faced". Should they only have the white faces towards the area to be calculated or should they simply just all be aligned?

Remember that SU doees not model truly curved surfaces. It approximates them with several flat faces. Turn on "hidden geometry" to see what I mean. You can specify how many "flats in a circle", which will increase accuracy at the price of performance. CB.

As daiku says the accuracy of the volumes for curved surfaces is only as accurcate as the number of facets you give those faces - number of swegments in the arc etc...
Ensure that all of the faces are in the same orientation (use context-menu orient faces) and every part of the object has a face so that the volume doesn't rty to 'leak out' ! In fact v2.0 orients all of the faces in the volume it makes for you... BUT better safe that sorry...
To ensure there are no other complications (at the moment) I recommend that you keep discrete volumes as separate groups - otherwise there can be confusing - imagine several touching 3D shapes atht are otherwise separate volumes - sometimes the calcualtion process can get muddle as to which face belons to what...There are fixes in the pipeline to trap these, but...
