I have a part as a multibody object and I would like it to show me the mass of the selected solid object in the list of materials, not the total mass. How do I make some objects have a mass of zero? In Inventor, it was possible to treat some solid objects as references and not treat them as masses.
"Delete/Keep Bodies" gives the effect I would like to get, but I thought there was an easier way than removing unnecessary solid bodys.
Thanks

Yeah, but when I want to make a BOM, I can't choose which solid bodies the program should sum up, it sums all up.

Correct. And zero added to anything is still zero.

One possible solution.
1. Select the body or bodies you want to use as reference (from the body folder, or using the solid body filter)
2. Invert Selection
3. Right click and select Material
4. Apply a material with 0 kg/m^3 density
Job done.
I had the same idea, but it is impossible to set the mass of the material to 0, I set 0.000001 and it works.
You could try a combination of these two links below. Essentially, create a weldments feature to break the solids into separate cut-list items, then add a 'weight' property to each cutlist item. Then you can manually force the 'weight' to zero in the cut-list properties dialog, but the others will retain the actual value.
I don't know that there's a one-click way to do it in a multibody part.
Typically for reference bodies that were used for intermediate modeling steps, I would put a "Delete/Keep Bodies" feature at the end of the feature tree that removes those and also helps prevents confusion for other users. Suppress or roll back above this feature when you need to access them again
Alternatively, if your reference bodies were surface bodies then they would automatically have 0 mass.
