Maneuvering the BIM modeling process can be complex without parametric creations from the Revit family, therefore we label it as the inevitable part of BIM. Family creations make the process quite simple, as they are made from components that are the building blocks of the digital model.
Understanding Parametric Family Creations
Understanding parametric family creations lies in demystifying the word parameters. Parameters refer to mathematical equations and formulas in Revit family software that provide the relationship between family elements. They act as the framework upon which familiar elements are created. In simple terms, parameters give us the relationship between component properties: width, length and depth.
These parameters are based on reference planes within the model. And these reference planes are labeled as dimensioned. Most importantly, parameters help us coordinate and manage digital. The Revit software allows the automatic or manual creation of these parameters.
Structural members such as doors, windows, roofs, walls, and floors are typical structural components that are coordinated through parameters.

Creation of the BIM Family
The creation of the BIM family is an indispensable part of BIM. It is through Revit families that MEP engineers access architectural, structural and engineering components to complete virtual models according to specifications. Think about building a specific component, i.e. a door with a specific feature, like a doorknob. This will be indicated on the virtual model with correct dimensions, construction materials and other related information. There are a multitude of components in a virtual model and creating families classifies them accordingly.
There are basically three types of Revit families: in-place, system, and parametric. The first two existing families and System BIM are project specific, therefore they are not preferred in the BIM modeling process due to their lack of flexibility. They are useless when dealing with multiple projects whereas Revit family parametric creation can be used for multiple projects.
Even more, the creation of parametric families can be used for facilities management purposes. This is more of an advantage for the owner. Can also be used as a built-in. Ideally, we can add details about the manufacturer, construction materials, models, dimensions and more information about certain components. This helps in managing and maintaining the facility.
Due to the lifecycle information we attach to components, building maintenance can also be simplified by creating parametric families. This helps us keep a record of assets and equipment.
Typically, the built-in library comes with predefined families in the software. However, this may not work with parametric family creations.
Revit parametric family creations
A family's parameters can be edited or modified. The crux of creating parametric families lies in the precision of adding parameters to characterize the shape, properties and finishes of the components. To achieve this, you need to have knowledge and experience in handling BIM. Additionally, BIM standards in a specific location must be considered.
Among others, to maneuver the creation of Revit parametric families, you need to understand basic features such as adding geometry, understanding structure, and categorizing components into relevant families. Ultimately, properties such as width, length and depth of the components of each family must be controlled appropriately, so this activity requires extensive experience in BIM modeling. New York Engineers has expert technicians who have mastered the art of parametric creation of the Revit family on various projects.
Understanding Revit Parametric Family Creation
The first thing is to understand the model and how to configure it. Creating families requires meticulous attention because creating parametric families does not work well with generic models. You need to choose the right template from the beginning and assign categories and subcategories accordingly. After the model, you need to draw reference planes and add dimensions and labels to them. After that add parameters and test them. The last step will be to align the geometries and lock the model. Without an experienced MEP engineer, this may seem unattainable or simply complicated to accomplish.
The creation of parametric families makes life easier for BIM model designers. This makes the whole process easier. Compared to other families, parametric is the best option due to its flexibility. Your components can be saved for later use in other projects. All you need to do is modify and edit them according to the project you are undertaking.
