weight of a set

[TECNOMODEL]

I'm noticing something weird.
I build a set, the various parts have all the material set with the right density and therefore their weight corresponds to reality.
but the weight is greater than reality. known that as density takes a value of 7,164 g/cm3, I imagine it is an average of the density of the various components as I have steel parts, cast iron, rubber commercial components etc.
Is there any settling to do to have the correct weight in the axieme?

I've already noticed.
in the past years I had to make an automatic cart where I had a maximum weight to respect, I worked as much as possible to lighten and, when we weighed it, we found almost 5% less than the theorist.
I don't think he does an average, if you take the individual weights and calculate the weight on an excel sheet, the total corresponds to that given automatically in the set.

 

[TECNOMODEL]

and therefore the error would be in the weights of the individual pieces?
I'm finding a difference over 20%, it really seems to me a lot.

 

[stefanobruno]

work on welded and then worked?

 

[TECNOMODEL]

No, no welded.
counts that the axieme is 43.8 kg, measured the real product 36 kg.
It really seems like an excessive mistake.

Hello everyone
to me had happened with previous versions (I do not remember which) where I had noticed a variation of mass and baricentro on the mirrored parts (the derived parts) for example a frame of a conveyor belt in sheet metal, the dx side had a weight and the sx flank (despite the correct set of style sheet, thickness and identical material), was a different mass and the baricentro completely "sballato"

I had hoped that I had a very derivative part and mirrored in the axieme but this is not:
the two parts have identical weight.
