Volume Measurement

Volume Measurement

(OP)
Is there any tool in NX, that allows you to do measurementsof the volume between some surfaces without making a body with them?
  

RE: Volume Measurement

If your model represents a volume of space bounded by surfaces but which have NOT been sewn together to form a solid body, you can use a function which, despite it's name, is actually a very old technique that has survived from before the days of solid modeling.  Go to Analysis -> Advanced Mass Properties -> Mass using Curves and Sheets...  Now this will work even if there are small gaps or openings in your model, however the larger the gaps the more the accuracy of the results will suffer, but if the volume is closed tight, even if the sheets are all separate sheet bodies it will work, however during the selection process you will be asked if the surface normals are all correct, or in this case, point AWAY from the center of the model (out into space).  If not you will have to use the reverse normal tool to fix any faces that are not correct and then restart the Analysis operation.

Generally speaking, if you have a volume closed by surfaces, it's better to sew them together and then perform a normal solid Mass Properties calculation, but this older legacy approach still does work, if you're careful.
