group density

[cacciatorino]

A colleague showed me a group of densities assigned. The problem is, it's wrong and the weight calculation of the group.

You know how to impose density on a group, and maybe take it off if it's already there?

it is not possible to set the density of a group but is the direct consequence of the density of the various parts. normally it is not visible because almost always in the group there are parts of different density. when shown, as in the image you have attached, it means that all parts within the group have the same density. to change it is sufficient to change the density of the parts.

The problem is that the sum of the weights of the individual parts is on 200 gr, while the group weighs 15 kg. Anyway, I'll give your info to my colleague, thank you very much!

Then it's probably the same problem I've had a while ago. The model we're talking about is probably a model imported from another system. happens in some cases that on imported models, even changing the properties of the parts, the group continues to have wrong properties. it simply solves by making a copy of the group and deleting the other model. prove it. Hi.

The problem is when the group is shared, then how do you replace all instances? Then let's hope that the pdm doesn't give a problem, the one in use sometimes is bad enough sometimes...

hi, I also saw this problem, I found it from the festo site if you download *.lsp, within it set a weight attribute.
as it suggested stefanoparducci create a new group and throw everything there erasing the old one, otherwise that set weight you will carry it behind the infinite and maybe on the inertias could cause big problems.

Are there no parts in density 1? this often happens with elements loaded from the web and farce the weight of the part and all the assembling.
By the way, does anyone know how to calculate the density of all parts of a group so as to quickly identify which one has density?
