To create a floor-based void in Revit, you will need to use the Model In-Place feature with a void extrusion. Here's a step-by-step guide, incorporating information from the provided reference:
Steps to Create a Floor Void:
-
Switch to a 3D View: Begin by opening a 3D view of your Revit project. This will allow you to visualize the void being created.
-
Initiate Model In-Place: Navigate to the Architecture tab, then click Component and choose Model In-Place.
-
Select Generic Models: In the Category dialog box, choose Generic Models and click OK.
-
Name the Model: Give the generic model a name that will help you identify it later, such as "Floor Void".
-
Create Void Extrusion: Go to Create > Forms and select Void Forms > Void Extrusion.
-
Set the Work Plane:
- Click Set in the Workplane panel.
- Choose Name in the Work Plane dialog.
- Select the level associated with the floor or a relevant reference plane. If you don't have a plane ready, make sure you create one before creating the void.
-
Draw the Void Form:
- Use the drawing tools to sketch the shape of the void you want to create within the floor. The void can be any shape you need, from simple rectangles to complex polygons. The depth of the extrusion should be greater than the floor thickness so that it will be cut out completely.
-
Finishing the Void:
- Once you have drawn the void shape, click on the Finish Edit Mode icon (check mark).
- Then click on the Finish Model button to finish and save your floor void.
Practical Considerations:
- Placement: Ensure your work plane is correctly set to the same level as the floor you're trying to modify.
- Shape: Complex shapes might require multiple void extrusions to achieve the desired results.
- Adjustments: You can modify the extrusion depth by adjusting its properties to ensure it cuts through the floor.
- Visibility: You can adjust visibility settings to control how the void is displayed in different views.
By following these steps, you can successfully create floor-based voids in Revit for design purposes such as stairwells or other openings.
