EC3 Builder Support

After exporting a Revit project, EC3 will attempt to detect which building elements could be refined by the EC3 Builders. These builders are a set of helper tools which allow you to automatically recognize and refine typical assemblies. For example, a single Concrete layer could be turned into Reinforced Concrete, a Metal Stud layer mass could be calculated according to its volume and other properties, etc.

To use this feature, after opening an exported EC3 project in a browser or using the Open in EC3 window, click the Next Decision button in the Revit or Custom view.

It will highlight the next element EC3 is proposing to apply a builder to.

For example, in this case it's a Concrete layer which could transformed into Reinforced Concrete by automatically adding a rebar. To do this, click the layer's quantity.

You will see two options: Concrete By Area and Concrete By Volume, so you can choose which dimensionality to use for this layer.

After clicking either of them (for example, Concrete By Volume) the builder dialog will open allowing you to choose how to calculate the required amount of rebar for this element.

By clicking Add Rebar By Concrete Volume, Add Rebar By Reinforcing Ration or Add rebar By Length, you'll make the builder to automatically add a Rebar layer for the Concrete layer using the selected principle to calculate the quantity.

By clicking the Accept button you'll confirm the calculated quantities and get the reinforced concrete assembly.

The EC3 Builders could help with Metal Stud layers too.

After the export, EC3 often is unable to reliably calculate the quantity of such layer, because it lacks material density. In this case, instead of quantity, the #VALUE! error is displayed in the quantity filed.

After clicking the quantity field of such layer, you can apply the Metal Stud builder to it.

It will help to calculate the realistic quantity.

After clicking the Accept button, you will get the properly calculated Metal Stud layer.

Apart from proposing to apply a builder, the Next Decision button also highlights other problems in the project, like missing quantities or EPDs, lacking an accurate material category, etc.
