Determine the Volume of an
Oddly Shaped Cavity
Have you ever needed to determine the volume of an oddly shaped cavity? Wouldn't it be nice to be able to do so easily? Here's how to go about determining the capacity of any cavity you can think up.

The basic steps to accomplish the above:
1. Open the drawing of the 3D model you wish
to show the volume of.
2. Open your 3D part model.
3. Create a custom property called "volume" & link it to
the 3D model's volume by
clicking FILE -- PROPERTIES.
4. Create a derived configuration (This will be the
configuration that shows the
volume of the cavity & be linked to the parent
configuration)
5. Extrude a cube around your part model (make sure it
will always be larger than
the object)
-- Make sure to uncheck "merge results' when extruding
the cube
-- Also make sure the cube is coincident to all of the
openings of your 3D part
model.
6. Now use the "combine" command & subtract your 3D part
from the cube.
7. You should now be left with a model representing the
volume of the cavity.
8. Now unlink & suppress the last few features in your
feature tree from the by right
clicking on them & going to "feature properties".
9. Go back to your parent configuration & suppress the
last few features -- you
should now see your original 3D model.
10. Go back to your derived configuration & un-suppress the last
few features -- you
should now see the volume of the cavity.
11. Go back to your 2D drawings.
12. Copy one of your views.
13. Change the configuration of that view to show the derived
configuration (volume
of cavity)
14. Now create a not inside that view & click LINK TO PROPERTIES
& link to the
volume of the cavity.
15. You can move this view off the page if you do not want it to
print -- but, move
the volume not back onto the drawing. . .
16. Now when you change the 3D model you will notice the volume
