Shadow Slice – Interior Shadow & Section Tool For SketchUp

Cut away walls and roofs while keeping their natural shadows. The essential tool for interior sunlight simulation and perspective section diagrams.

[ FEATURES ]

The Plugin has 03 Core Features.

1-Click Interactive Slicing

1. 1-Click Interactive Slicing

Forget tedious manual section setups or deleting roofs. Simply click the + Add Slice Tool on the Shadow Slice dashboard, click directly on the Group or Component you want to cut, and you're done!

  • Non-destructive slicing that keeps your original 3D geometry intact.
  • Shadows from sliced walls and roofs continue casting physically accurate shadows inside.
Centralized Dashboard

2. Centralized Visual Dashboard

All your active Shadow Slices are managed visually inside a single, intuitive control panel. Instantly toggle visibility, adjust slice positions, or customize section fill colors on the fly.

  • Manage multiple slice planes simultaneously with independent toggles.
  • Customizable slice line weights, edge styles, and cross-section fill colors.
Smart Style Management

3. Smart Style Management

Shadow Slice automates the background style configurations, layer management, and shadow settings, letting you focus 100% on your design concepts without breaking exterior lighting.

  • One-click activation of architectural diagram styles.
  • Automatic scene creation for sequential solar presentations.
[ ANALYTICAL USE CASES ]

How Shadow Slice Transforms Your Workflow:

Interior Natural Light Analysis

1. Interior Natural Light Analysis

Shadow Slice makes ceilings and upper walls transparent to the camera while keeping them completely solid to sunlight. This allows you to look inside and analyze realistic natural light distribution throughout the entire floor plan.

Smart Section Compensation

2. Smart Section Compensation

Traditional section planes let sunlight flood in from the cut plane, completely ruining interior shadow accuracy. Shadow Slice automatically compensates for the removed section, keeping shadow casting 100% physically accurate.

Section-Based Shadow Studies

3. Section-Based Shadow Studies

Analyze interior shadow behavior directly within longitudinal or transverse section views. Perfect for daylighting reports and client documentation.

Perspective Cutaway Visualization

4. Perspective Cutaway Visualization

Create stunning 3D perspective sections that communicate spatial flow and interior massing without losing environmental context.

[ FAQ ]

Frequently Asked Questions

1. How is Shadow Slice different from native Section Plane?
SketchUp’s native section cut removes geometry completely, allowing exterior sunlight to pour directly through the cut opening, which destroys realistic interior lighting. Shadow Slice makes the cut geometry invisible to your camera while retaining 100% of its shadow casting.
2. Does Shadow Slice modify or damage my model?
No. Shadow Slice operates completely non-destructively. You can turn off or delete slices at any time, instantly restoring your original model setup.
3. Which versions of SketchUp are supported?
Shadow Slice supports SketchUp 2020 through SketchUp 2026 on Windows and macOS (including Apple Silicon).
4. How do I activate my license for the Pro version?
For Extension Warehouse, your license is linked directly to your Trimble SketchUp account. For Gumroad / SketchUcation purchases, open the Shadow Slice panel in SketchUp, click "License", and paste your license key.
