Thanks for that.
For me, it is generally just one material - steel (structures) or
aluminium (windows and curtain walling) so I don't have them on
separate layers. I also have to provide full cutting lists with each
individual element listed and an estimated mass for it.
What prompted this was a rather messy job where I was fed incorrect
information on the total job mass. I quoted a $/tonne figure, but it
turns out that the fabricator is claiming that the actual tonneage is
around 30% less than the figure I have worked out. Of course their
transport and galvanising records clearly show this 30% discrepancy.
With some 400 assemblies and each assembly comprising something like 6
or more individual items, I almost wore the spots off my calculator.
I will have a look through things and see what I can use. It is a pity
that AutoCAD does not let you simply nominate what the default
material bulk density is - at least I have not been able to find it.
Thanks again.
