Creating instances of families is a crucial step in Revit modeling. It allows you to populate your projects with the defined elements. This process, once understood, streamlines the workflow and enables consistent application of design intent. Modifying instances allows for adjustments to specific elements without affecting the underlying family definition, maintaining data integrity and design control.
Creating Family Instances
Creating instances involves placing copies of the family definition into the project. This is often done using the ‘Place’ command, found in the appropriate Revit panel. The specific method depends on the type of family being instantiated. For example, placing a wall instance involves selecting the wall family and clicking on the desired location in the project view.
Revit prompts for parameters like length and height, allowing for customization. Similar procedures apply to other families like doors, windows, furniture, and custom objects. The family instance is then linked to the overall project model, inheriting its attributes and parameters. This process is essential for constructing a detailed and accurate representation of the design.
Modifying Family Instances
Family instances can be modified in several ways, offering flexibility in design adjustments. These modifications typically involve adjusting parameters defined within the family itself. For example, changing the height of a wall instance affects only that specific instance, not the family definition. This method ensures that modifications to a single instance do not alter the original family definition, maintaining data integrity.
This also allows for efficient modification of multiple elements at once, a crucial element for large-scale projects. Parameters can be modified directly within the project view, offering quick and convenient adjustments.
