Understanding Void Cutting in Revit Walls
Cutting a void in a wall in Revit is essential for creating openings and custom designs in your architectural models. This process involves creating a void form that interacts with the wall geometry to achieve the desired result. Below is a comprehensive guide detailing how to cut a void in a wall in Revit, broken down into clear, actionable steps.
Steps to Cut a Void in a Wall
1. Access the Appropriate View
Start by opening an elevation or section view of your wall. This perspective allows you to see your wall more clearly and to select the wall conveniently for modification.
2. Initiate the Wall Opening Command
Navigate to the Home tab on the toolbar. In the Opening panel, locate and click on the “Wall Opening” tool. This function prepares you to create a new opening in the selected wall.
3. Select the Target Wall
Click on the wall where you want the void to be created. Ensure the right wall is chosen, as this action is crucial for the subsequent steps.
4. Design the Opening Profile
With the wall selected, sketch your desired opening shape directly on the wall surface. The most common method is to create a rectangular opening, but other shapes can be used depending on your design requirements.
5. Modify the Opening as Needed
If adjustments are needed, go to the Modify tab and select the opening you created. This allows for resizing, moving, or changing the configuration of the void to meet specific design needs.
6. Finalize Your Design
Once the opening is satisfactory, complete the process by confirming your changes. This will update the wall geometry to reflect the new void. Review the 3D view to ensure the void appears as intended.
Creating a Void Form in Revit
If you require more advanced cutting techniques, such as creating complex void shapes, follow these steps:
1. Open the Family Editor
Access the Family Editor by creating a new family or editing an existing one. Opt for a face-based generic model to give you the flexibility needed for creating voids.
2. Generate Solid Geometry
Within the Family Editor, construct a solid form first. This can be a straightforward shape like a box, or a more complex geometry depending on your design specifications.
3. Introduce a Void Form
Create a void by drawing a closed loop that intersects the solid geometry. Select the loop and navigate to the Modify tab to transform this closed loop into a void form.
4. Position the Void Form
Align the void form appropriately with your solid geometry, ensuring it is placed correctly to cut through the solid.
5. Join the Forms
Make sure the newly created void interacts correctly with the solid by using the “Cut Geometry” tool in the Modify tab. Select the cutting void and the solid geometry, ensuring they join correctly.
FAQ
1. Can I create non-rectangular voids in Revit?
Yes, Revit allows for the creation of various shaped voids using drawing tools such as lines or polygons before converting them into void forms.
2. What types of walls can I cut voids into?
Voids can be cut into various types of walls, including basic walls, curtain walls, and other wall types that are part of Revit’s architecture.
3. Is it possible to modify the size of a void after it is created?
Absolutely. You can select the void opening and use the modify tools to alter its size, shape, or position as needed to fit your design specifications.
