Smart Slice

Overview

The Smart Slice tool leverages Revit’s native “Parts” engine to subdivide wall faces and columns into smaller, independently paintable regions. It is the perfect tool for designing wainscoting, tile dados, split-level finishes, or complex facade paneling.

Instead of splitting the actual 3D wall elements—which can ruin your structural model and wall joins—Smart Slice safely overlays a divided “Part” geometry. It also works in perfect tandem with the Smart Paint tool, automatically unlocking the new parts so they are instantly ready for materials.

Interface Breakdown

1. Slice Modes

Choose the scope of your slicing operation:

• Room Mode (All Boundaries): Click a Revit Room, and the tool will automatically find and slice every single bounding wall face inside that space at once.
• Face Mode (Individual): Click individual walls, existing parts, or architectural/structural columns to slice them specifically.

2. Horizontal Slicing

Define the height and location of the horizontal band you want to create across your wall.

• Bottom Level & Offset: Set the starting elevation for the slice. (e.g., Level 1 + 0mm).
• Top Level & Offset: Set the ending elevation for the slice. (e.g., Level 1 + 1200mm to create a standard tile dado).
• Note: The tool will automatically read the wall’s geometry and cut a perfect horizontal strip between these two defined elevations.

3. Vertical Slicing

• Enable Vertical Slicing: Check this box to subdivide the horizontal band into vertical panels.
• Divisions: Input the number of equal vertical segments you want to create along the face of the element.

4. Action Bar & Smart Paint Integration

• Slice: Initiates the command to pick elements/rooms and generate the divided parts.
• Remove (Merge/Restore): If you make a mistake or want to remove a slice, use this mode. Clicking previously sliced parts will merge them back together and restore the original, unified wall face.
• Paint (Switch to Smart Paint): A dedicated quick-switch button. Once you have finished slicing your walls into panels, click this button to instantly close Smart Slice and open the Smart Paint palette to begin applying materials to your new regions.

💡 Tips

• Auto-Unlocked Materials: A major frustration with native Revit Parts is having to manually uncheck the “Material by Original” property for every single part before you are allowed to paint it. Smart Slice does this for you automatically. As soon as a slice is generated, it is instantly unlocked and ready for Smart Paint.
• Non-Destructive Modeling: Because this tool uses the Revit Parts engine, your core architectural walls are never actually cut, split, or damaged. If you turn off “Show Parts” in your Revit View Visibility settings, your walls will look completely normal.
• Re-Slicing Existing Parts: You don’t just have to slice walls! If you have already sliced a wall horizontally, you can select the newly created top or bottom Part and run the tool again to slice that part further.
• Column Wrapping: The selection filter explicitly allows for Architectural and Structural columns. You can easily slice the bottom 500mm of a concrete column to paint a safety-yellow warning base.
