Elements m2 on bim softwares

[Joostm]

Hi,

We have projects where we need to model everything in great detail so the contractor can calculate the m2 of materials he needs. Example: m2 of plasterboard around an opening or m2 of a complex profile plate.

When you open a model in solibri the m2 is usually not accurate. I find myself having to model everything separately ( 2 walls + 1 slab) or adding formulas to properties to make the m2 +/- accurate.

It would be save a lot of time if one could define the perimeter that should be calculated for the m2 of the element. (red Line) inside the complex profile for instance.

Have you tried using a 'surface' schedule rather than an 'element' or 'component' schedule?

i have seen the Contrabim tutorial and i do see it works accurately in schedules but my point is in the m2 that you get as an surface area when you open the IFC model with solibri/bimcollab.

There the m2 are not accurate so it leads to the mentioned solutions that make it very un efficient
