How to calculate the Weight percentage in soliworks...?

....

1 Answer

I don't think I understand the percentage part but bear with me ...
To calculate the a model's weight you need to set a material to it so SolidWorks can figure out the density of your model, do that by Edit>Appearance>Material then choose the desired material ... then just go to the Evaluate tab and choose Mass Properties; it'll give you a lot of informations and one of them is the mass ...
Now, if you want to calculate the percentage one part have over the assembly, do that to all the parts and the rest is plain math ...
If you want the mass percentage and the whole model have the same material in real life then skip all that and calculate the volume percentage and it'll turn out the same, you can get the volume for each part from the Mass Properties ...
Sorry for being long in explaining and if something is unclear, please tell me ...
A small advise, give more details when you ask a question, explain the situation ... it'll make people more willing to help you ...
