Edge Length Measure v1.0.0

Blender 插件，用于测量选定的网格物体，并直接在 3D 视口和侧边栏中显示每条边的长度及总边长。

专为精确测量、建模分析和技术工作流程而设计。使用基于求值依赖关系图的数据，完全支持修改器变形后的几何体。

兼容 Blender 5.0+ 版本。

设计目的

本插件旨在物体模式下测量网格边长。

在 Blender 中，当应用了骨架、细分曲面或其他变形修改器时，物体模式下显示的网格几何体可能与编辑模式下的原始网格存在显著差异。

Blender 自带的测量工具和大多数现有插件主要在编辑模式下运行，测量的是基础网格几何体，而非包含修改器变形的求值网格。

然而，在许多技术性建模工作流中，需要测量修改器应用后、在物体模式下实际显示的可见几何体。

Blender 并未提供原生工具来直接测量物体模式下求值网格的每条边长。本插件正是为解决这一限制而开发。

它能够在不应用或破坏修改器的情况下，精准测量求值网格上的边长。

功能特点

• 注册多个网格物体

• 在 3D 视口（物体模式）中显示每条边的长度

• 显示每个物体的总边长

• 显示所有已注册物体的总合计边长

• 当网格或修改器发生变化时实时更新

• 完全支持修改器变形后的几何体（骨架、细分曲面等）

• 基于场景设置的单位格式化显示（毫米、厘米、米、公里）

• 每个物体的可见性切换

• 简洁高效的侧边栏界面

Blender add-on that registers selected mesh objects and displays individual edge lengths and total edge length directly in the 3D Viewport and Sidebar.

Designed for precise measurement, modeling analysis, and technical workflows. Fully supports modifier-deformed geometry using evaluated dependency graph data.

Compatible with Blender 5.0+.

Purpose

This add-on was created to measure mesh edge lengths in Object Mode.

In Blender, when modifiers such as Armature, Subdivision Surface, or other deformation modifiers are applied, the mesh geometry displayed in Object Mode can differ significantly from the original mesh in Edit Mode.

Blender's built-in measurement tools and most existing add-ons primarily operate in Edit Mode, measuring the base mesh geometry rather than the evaluated mesh that includes modifier deformation.

However, in many technical and modeling workflows, it is necessary to measure the actual visible geometry as it appears in Object Mode after modifiers are applied.

Blender does not provide a native tool to measure individual edge lengths directly in Object Mode for evaluated meshes. This add-on was developed to address that limitation.

It enables accurate measurement of edge lengths on the evaluated mesh without applying or destroying modifiers.

Features

• Register multiple mesh objects

• Display individual edge lengths in the 3D Viewport (Object Mode)

• Display total edge length per object

• Display grand total edge length across all registered objects

• Real-time updates when mesh or modifiers change

• Fully supports modifier-deformed geometry (Armature, Subdivision, etc.)

• Unit-aware formatting (mm, cm, m, km based on Scene settings)

• Per-object visibility toggle

• Clean and efficient Sidebar interface
