how to calculate weight of a set

[gil]

Hi.
I have built a small test structure, now I would like to calculate its weight.

the structure has been realized combining two separate frames, each of which realized starting from a cube, on the vertices has been inserted of the tubular. on the tubular subsequently welded plates. .

Of course, I need the weight of the pipes and plates, not that of the generator cubes. How can I do that?

I have tried in these ways
1) from the browser select the assemblies and parts of my interest and then go to “iproprietis”. does not work because the “physical” tab does not appear with multiple select objects
2) from the menu in high selections “material count” (bill material). I can not remove the presence of the generator cubes and do not sum the weights of the different parts
3) I open a file “.idw” I insert the model and then “list parts”. I can't get a lot of weight.
4) Text command, select the physical values of the model to obtain weight. Once again there is no way to remove the generator cube from the total value.

I don't know what you want. ideas? because I can't even do something so trivial.

try to open the cubes and in the "physical" tab write "0" to the mass voice.

Thanks, but it doesn't seem possible, values are blocked.
the only thing I can do is set the cube material with "air" which weighs little, although it is not possible to descend below 0.001g/cm^3.

is not a great result ...

Open your frame, in the browser search for the particular that acts as a model to build it then dx key, distinct structure components and "refer" tick. This way excludes the component in calculating physical properties

thank you, but it continues to be present, even if I put it as a reference or ghost.

I try, too. to the generator cube eliminates a face, so as solid becomes superfice and then mass 0

hello to all and thanks
Davide75's advice was right, my fault I didn't do it well.
Here a video for posters that illustrates the thing.http://www.youtube.com/watch?v=ffqc4fcqggo
