How IMPACT works with Revit

Common – Local – Project
Following the usual IMPACT workflow, every company should work on creating a company standard on three levels.

Common – the initial company standard used at the highest level. Basically, components, definitions, and settings which are common for the whole company. 

Local – if a company has different divisions or departments, they can be differentiated by using the local levels. Basically, components, definitions, and settings which are common for the specific division. 

Project – contains project-specific components, definitions, and settings which might not be used before or in the future.

Figure 1. Schematic representation of the IMPACT Company Standard.

The IMPACT company standard for Revit mainly contains two file types. 
XML files (e.g. rebar templates) – a mark-up language that contains encoded information describing data used by applications
Revit families (column, beam, Cast-in Material…) – a solid form controlled by constraints (rules) and forming different components by changing its parameters. 

The families are organized in a specific hierarchy. This hierarchy is used to organize the Revit model.

The whole model in Revit is based on different elements. There are three main categories of elements:

• Modeling elements available in all parts of the project (wall, ceiling, floors)
• View-specific elements that are only visible I n this view where they are created (text, lines)
• Support elements (datum elements) are general support elements to help create model environment (Level, reference planes)
