Revit Family Creation

Revit is one of the most powerful tools in the architectural and engineering world. It is also very much prominent for the construction industry. With the coming age technology and progress in the industry it has become a highly competitive software and has largely contributed to BIM content creation. 

Revit family creation is one of the most prized services of Revit. It has become almost an indispensable part. Here we will be clarifying all your doubts about Revit Family creation. At the end of this piece you will understand the power of Revit. Even if you have no idea of Revit software you will get comprehensive details on it. 

Getting started with a Revit family creation is an extremely important step towards the success of your project. Whatever you create in the Revit software, automatically becomes a part of the Revit family. But knowing how to change and edit the existing families is quite a work which needs understanding. 

Families are a group of components that have common characteristics of graphical representation known as parameters. Every element such as the wall or column belongs to a hierarchy. The Revit ones tops the hierarchy. These categories are of two types:

Annotation categories: Contains texts, dimensions and tags.

Model categories: Consists of the building modelling elements. For example windows, doors, floors, and walls.

The types of families you are creating is another important aspect of the architectural family creation. There are 3 types of Revit families, which are as following:

System Families: They create the basic features that are used in the assembling process at a construction site. For e.g., walls, floors, doors, windows, ducts pipes etc.

There are certain system settings that are a part of the project environment like the grids, levels, viewpoints and drawing sheets.

The system families do not need to be loaded from external files or other locations. They are predefined in the software.

Loadable Families: They create the following

  1. The building elements that are bought and installed in a constructed building like doors, windows, fixture, furniture casework etc.
  2. System elements that are bought and installed in a building like air handlers, plumbing equipment, boilers, and water heaters.
  3. Few of the annotation elements which can be customized like the title blocks and symbols.

It is mostly seen that loadable families are created in the Architectural BIM Modeling because of its customizable feature. These are created in external locations and imported from there, or loaded in the project. There are loadable families having different types, and for them type catalogues can be created. This makes sure that only the needed ones are loaded.

In place families: These are exquisite types that enable one to create unique elements for the designated project only. These components are not to be found in any other project. The in-place geometry can be created accordingly to refer the adjustments and geometrical elements to other projects. An in-place element has a single family type. Creating an in-place element can be done with the same family editor tools such as the loadable family.

Points to remember in parametric Revit Family Creation

  • The family should have standard types and types catalogue.
  • The data in the family should be thoughtfully managed and organized.
  • The designated parameters in a family should be proper and clear.
  • The file size of the family should be as low as possible.
  • Specific and appropriate categories should be given to the family.
  • The LOD (level of detail) needs to be considered properly.
  • The right amount of data should be present in a family.
  • The reference lines in a family should be prioritized.
