Shadow Slice Pro 2.0 - Interior Shadow & Section Tool for SketchUp

Cut away walls and roofs while keeping their natural shadows. The perfect tool for interior sunlight simulation

[FEATURES]

The plugin has 03 core features.

1. 1-Click Interactive Slicing

Forget tedious setups. Now, you just click the “+ Add Slice Tool” on the dashboard, click directly on the Group/Component you want to cut, and you’re done!

2. Centralized Dashboard:

All your Shadow Slices are now managed visually within a single control panel. You can easily toggle visibility or change the color of your slices on the fly.

3. Smart Style Management

Minimize manual setups and streamline your workflow, letting you focus entirely on your design ideas.

[Analytical Use Cases]

How it Transforms Your Workflow:

1. Interior Natural Light Analysis

Shadow Slice makes the ceiling transparent but keeps the shadows solid. This allows you to look inside and analyze natural light distribution throughout the entire house without changing the actual lighting conditions.

2. Smart Section Compensation

This tool reconstructs the parts of the building removed by the Section Plane. The compensated portion is transparent to the eye but still blocks sunlight (except for glass), ensuring that your interior lighting analysis remains physically accurate.

3. Section-Based Shadow Study

Specially designed to analyze interior shadow behavior directly within a section view. It is the perfect solution for documenting how sunlight penetrates a space for professional design reports.

4. Perspective Cutaway Visualization

Create perspective sections that help viewers easily visualize the entire architectural mass. It provides a perfect balance between maintaining the building context and revealing the interior space.

Why Choose Shadow Slice?

The Problem: SketchUp’s Default Sections

If you’ve ever done interior shadow or energy analysis, you’ve likely hit a major limitation in SketchUp: the default Section Plane does not block sunlight. When you use a section cut to hide the roof, the sun shines directly into the interior as if the roof doesn’t exist. This makes accurate natural lighting analysis nearly impossible.

The Solution: How Shadow Slice Works

Feb Shadow Slice automates the complex manual workflow required to fix this by creating an intelligent “Ghost Slice” copy of your model.

Accurate Shadow Casting: Reconstructs the geometry removed by the Section Plane to ensure it continues to cast shadows accurately while remaining invisible to the camera.
Non-Destructive Workflow: The tool is incredibly safe. Your original model remains completely untouched, ensuring your design process is never disrupted.
Intelligent Entity Processing: Automatically handles materials and back-materials for nested groups and components to ensure consistent transparency without losing structural data.
