why does my sw software apply a weight in the bom when a material has not been selected yet? This gave me and my client "big ones", when it placed an amount of weight much less than proper amount, into the bom. You would think if material is not selected at part level,... a arbitrary number would not be parametrically placed into the bom. It was overlooked, not double checked, and was a mistake and cost us big money. If it had correctly said zero, there would not have been a problem.
Thank you for your quick response! I think I understand you correctly Deepak: that is how SW works.
I have decided to have a column in the bom that specifies the material so that this won't happen again - hopefully.
And I may have exaggerated the consequences of the error a bit - my bad, hopefully it won't cost that much money, only headache.
My boss/client went easy on me so far, and I shall pass that mercy on. Sorry I got excited!
In addition to that you can set a material to your part templates
SW has a default density under document properties which is used to define the weight and other related values in case material is not defined.
You can set to any required value but not 0. But if you remove material from the model then it would revert back to the default value.
