Here is another way to find out how much water (or whatever) a bottle will hold. This example we’ll be combining 2 bodies. Lets take a look.
The first thing I’m going to do is sketch a rectangle. I have a plane in the middle of this bottle that I’m going to start my sketch.
Next we’ll do a simple mid-plane extrude. The only thing I’m going to do is drag the extrude out so that it goes past the exterior of the bottle. You also want to un-check merge result.
When you have finished with the extrude you’ll notice that we now have 2 solid bodies in our feature tree.
Now we can Combine these bodies into one. Holding down your Ctrl key, select both bodies in your feature tree and RMB (right mouse button) and select Combine
What we want to do now is Subtract the “water” (the rectangle block) from the bottle. In the Main Body box select the extrude we created. In the Bodies to Subtract select the bottle.
After you select the Ok check, you’ll get a dialog box asking which bodies you want to keep. In this example, I’m only interested in how much water this bottle will hold. So I’m going to select Body 2 (Which is highlighted in the dark greenish color)
After you hit Ok, you are left with just the interior of the bottle.
