🔪 Cut Floors

Cut Floors performs advanced floor splitting operations with support for model lines, curves, complex geometry, and room boundaries, addressing Revit's limited floor division capabilities and eliminating manual floor redrawing.
Version 1.1 | Specials

Overview​

While Revit's standard floor division methods are limited to create parts functionality or manual floor redrawing (both time-intensive and inflexible), this tool addresses those limitations by providing automated floor splitting and opening creation using various geometric elements and room boundaries. This enables rapid floor division using model lines, splines, ellipses, circles, and actual room geometry with independent floor type control, as well as opening creation when cutting geometry forms closed shapes within floors, significantly reducing the time spent on repetitive floor modification tasks that are fundamental to finish planning and space coordination workflows.

Key Features​

Usage includes:

  • Multi-Geometry Cutting: Split floors using model lines, splines, arcs, ellipses, and circles.
  • Opening Creation: Create floor openings when cutting geometry forms closed islands within floor boundaries.
  • Complex Curve Support: Handle splines, arcs, and organic shapes for non-linear floor divisions.
  • Multiple Floor Processing: Split multiple floors simultaneously with single cutting geometry.
  • Cutting Element Management: Option to automatically delete cutting geometry after operation.

Requirements​

Before using Cut Floors, ensure your environment meets the following prerequisites:

 Autodesk Revit: From version 2020 to newest.
 NonicaTab: NonicaTab Pro.

note

Cut Floors can only split floors with lines or rooms that split floors in two parts. If more parts are required, they need to be handle sequentially in different operations.

Usage​

Understanding Standard vs. Enhanced Floor Division Methods​

  1. Standard Revit Floor Division:
    • Create Parts Limitation: Create parts functionality with limited geometric flexibility
    • Manual Redrawing: Time-intensive manual recreation of floor boundaries
    • Limited Curve Support: Difficulty handling complex curves and organic shapes
    • Single Floor Processing: Process floors individually for each division operation
  2. Enhanced Floor Division (This Tool):
    • Geometric Flexibility: Support for lines, splines, arcs, ellipses, circles, and room boundaries
    • Automated Processing: Split multiple floors simultaneously with single cutting operation
    • Complex Shape Support: Handle organic curves and non-linear division patterns
    • Independent Control: Create separate floor elements with individual type control

Basic Floor Cutting Workflow​

  1. Navigate to NonicaTab Pro → Cut Floors.
  2. Floor Selection: Select the floors you want to split (can select multiple floors).
  3. Cutting Geometry Definition: Choose cutting elements:
    • Model Lines: Draw or select existing model lines for linear cuts
    • Splines: Use splines for organic, curved divisions
    • Arcs: Select arcs for radial cutting patterns
    • Circles/Ellipses: Choose circular or elliptical cutting boundaries
    • Rooms: Select room boundaries for finish-based floor division
  4. Cutting Element Management: Choose whether to delete cutting geometry after operation.

Floor Opening Creation Applications​

  1. Island Geometry Operations:
    • Closed Shape Recognition: Tool automatically detects when cutting geometry forms closed shapes within floor boundaries
    • Opening vs. Division: Closed island shapes create openings; edge-to-edge cuts create floor divisions
    • Complex Opening Shapes: Create openings with organic splines, circles, ellipses, or custom polygonal shapes
    • Multi-Opening Processing: Generate multiple openings simultaneously using multiple closed geometric elements
  2. Architectural Opening Applications:
    • Stair Openings: Create custom-shaped stair openings using splines or complex curves
    • Elevator Shaft Openings: Generate precise elevator shaft openings with rectangular or custom geometry
    • Skylight Openings: Create floor openings for skylights with circular, elliptical, or custom shapes
    • Decorative Features: Generate openings for architectural features like water features or planters
  3. MEP and Structural Integration:
    • Service Coordination: Create floor openings for major MEP equipment or risers
    • Structural Coordination: Generate openings that accommodate structural elements passing through floors
    • Access Requirements: Create openings for maintenance access to building systems
    • Future Flexibility: Design openings that accommodate future building system modifications

FAQ​

Create Parts has limited geometric flexibility. This tool provides automated splitting using various geometric elements including organic shapes and actual room boundaries, creating independent floor elements rather than parts.

Room-based floor division aligns floor finishes with architectural programming, enabling different finishes for kitchens, offices, and other spaces. This creates logical floor divisions that match functional requirements and simplifies finish specification and coordination.

The tool provides an option to automatically delete cutting geometry (like model lines) after the operation. For rooms, this option doesn't apply since rooms are never deleted. Choose based on whether you want to keep the cutting geometry for reference or clean up the model.

The tool may have limitations with very irregular or complex room geometries. For standard room shapes, it works reliably, but extremely complex or unusual room configurations might require alternative approaches or manual adjustments.

Yes, you can select multiple floors and use the same cutting geometry to split them all simultaneously. This is efficient for applying consistent floor divisions across multiple levels or areas, ensuring coordination between different floor levels.
