What Is Free Form Element in Revit?

Understanding Free Form Elements in Revit

Creating free form elements in Revit is a technique that allows users to model complex shapes that traditional geometric forms cannot achieve. Free form elements are particularly useful in architectural design, where organic shapes and non-linear surfaces are often required. Here, we will explore what free form elements are, how to create them, and their importance in the design process.

What Are Free Form Elements?

Free form elements refer to the versatile shapes created within Revit that do not conform to standard geometric forms, such as rectangles or circles. These elements can take on any shape, making them indispensable for creative designs that require unique silhouettes and intricate details. Unlike bounded shapes, free form elements provide designers with the flexibility to manipulate the geometry as needed throughout the modeling process.

Step-by-Step: Creating a Free Form Element

  1. Initiate the In-Place Mass Environment

    • Begin by navigating to the Massing & Site tab in the ribbon at the top of the workspace.
    • Click on the "Conceptual Mass" panel and select "In-Place Mass". This opens a new environment where you can start modeling.
  2. Defining the Mass

    • In the dialog box that appears, give your in-place mass a unique name. Choosing a descriptive name will help with identification later on.
    • After naming, you will gain access to a variety of modeling tools tailored for conceptual design.
  3. Begin Form Creation

    • Use the available sketching tools to create the base form. Depending on your design needs, you may utilize tools like lines or curves to define your shape. Follow the guidelines to complete a closed loop to create a solid mass.
  4. Manipulate Your Form

    • Select the newly created loop or profile. Utilize the modification tools to refine your shape. Adjust vertices, edges, and curves to achieve the desired organic design.
  5. Finalizing the Mass
    • Once your form is to your satisfaction, navigate to the Modify tab. You will find an option labeled "Finish Mass". Click on it to exit the editing environment and solidify your design.

Practical Applications of Free Form Elements

Free form elements are highly beneficial in various architectural scenarios, including but not limited to:

  • Sculptural Elements: Designing features that serve as focal points in a building, such as a unique roof or an eye-catching wall.
  • Landscape Architecture: Creating forms that blend seamlessly into natural settings, enhancing the harmony between built structures and the environment.
  • Interior Design: Formulating custom furniture designs or wall panels that break traditional norms and elevate the aesthetics of interior spaces.

Frequently Asked Questions

1. Can I edit free form elements after they are created?
Yes, free form elements can be modified even after they are created. You can select the element and adjust its vertices or curves using the Modify tab’s editing tools.

2. Are there any limitations to creating free form elements in Revit?
While free form elements offer extensive flexibility, they can be complex to manage concerning detailing and documentation. Some users may find performance issues if the forms are highly intricate or involve a large number of facets.

3. How do free form elements impact the overall building model?
Free form elements can significantly enhance the visual appeal of a building, providing unique architectural expressions. However, they also require careful consideration in terms of construction feasibility, material choices, and integration with standard building components.
