You can buy “Azerilo Smart Tools” instead of this add-on. This add-on, along with seven others, is included in that package at a significant discount.

Effortless Mesh Symmetry Detection and Fixing

Take control of your mesh symmetry with Symmetry Checker, a powerful yet lightweight Blender addon designed to detect and correct asymmetry in your 3D models—perfect for character modeling, hard surface design, and cleanup workflows.

Key Features:

• Intelligent Symmetry Detection
  Quickly identify asymmetric vertices along the X, Y, or Z axis. Selected vertices are automatically highlighted, allowing you to fix issues with precision.

• Customizable Threshold
  Fine-tune the tolerance for detecting symmetry with a user-defined threshold, ensuring accurate results even for high-resolution models.

• One-Click Symmetrize Tool
  Fix symmetry instantly using Blender’s native symmetrize operation, with full control over the mirror direction (e.g., -X to +X, +Y to -Y).

• Seamlessly Integrated UI
  Access everything from the 3D Viewport Sidebar under the “Symmetry Checker” tab. Clean, intuitive, and non-intrusive.

• Real-Time Feedback
  Get clear feedback right in Blender’s status bar: ✅ for symmetric meshes, ❌ for asymmetry detected.

Ideal Use Cases:

• Cleanup scanned or sculpted meshes

• Ensure topological accuracy before rigging or animation

• Model hard-surface objects with structural symmetry

• Debug accidental vertex edits
