Unable to calculate volume

i am trying to get my object into any programme that reads surface files for prototyping so i would really love to know what this is

Without seeing the object, difficult to tell what’s wrong… Your message doesn’t give us much info either… In order to calculate volume, objects must be closed (watertight). Is that the case with your object? There are some workarounds for special cases, but before going into those, it would be good to see what the problem is.

Its is water tight but after updating rhino i was able to since i read somewhere that the version of rhino was the reason for this

Hi Mitviz - There was a bug and then a fix for Volume at some point, so make sure you have the latest service release (SR9). That may fix it, otherwise, please post the file or send it to tech@mcneel.com.

thanks,

Yeah the update really fixed my problem
