Calculated values in material takeoffs

[anthony.doyle]

Can anyone help??

I am trying to do material takeoffs for combined areas of conc beams, floors, columns and walls. We are trying to achieve a total concrete area for a project (surface areas for floors and beams)

This works well as a multi category takeoff, however with framing members (conc beams) the areas given are for all 6 sides of the beam, not just the top surface area.

Now I can add a calculated value in to achieve this, but all the other elements area values disappear (See attachement). Is there a way I can achieve this or is it just not possible?

What range of formula staements can we have in the calculated values???

Can anyone help?

Did you try shared parameters?

Later, when I have more time I'll give it a try.

I have tried shared parameters. This works for concrete beams.......but cannot apply to floors. Also the shared parameters will not calculate. So this didn't seem to work, unless I have done something wrong?

Thanks for the suggestion. Any other ideas?
