Hi

I have a question In Topic I raised the following:

Now My question It is When Estimate Volume of steel columns How Account Calculation  Is؟

And Also Weight Total Structures How can We calculated?

I know that:

Cross section * length = volume

But The parameter Which Part Column Defined Edit Family Look at Something I did not see.

hi

I compared  Between Revit And Inventor :

I Made A Beam with:

L 4000mm and IPE 220 In the Both software(Revit-inventor)

Calculation Weight As follows Is shown:

Revit Calculation Weight:

Inventor Calculation Weight:

What is the weight difference?

Is my calculation is incorrect?

According to Euronorm 19-57 the weight per meter for a IPE 220 profile is 26.2 kg/m and section area 0.00334 m2.

4 m x 26.2 kg/m = 104.8 kg which means that the section area for a IPE 220 Revit family type is not that exact (3% difference). In a 100 ton project the difference is worth 10-15 000 €.

Well it's also of good practice to check the density of steel 7800...7850 kg/m3. There's also a round-off error involved and I recommend you to check the steel profiles you use using a handbook.

It's frustrating but you better check the OOB content before using it for real world purposes.

hi

Thank you very much for the answers and tips.

I suggest that you first give position numbers for all members to be schedule. Use the extension 'Element numbering' under ribbon title 'Extensions'. This extension will put a position number into the 'Mark' parameter.

In the Properties window for your framing schedule you select 'Formatting', select schedule key/ parameter 'Weight' and select 'Calculate totals'. Remember to include 'Mark' into your schedule.
