EdgeFlow

MODELINGTOPOLOGY TOOL
📖2 min read

Introduction​

EdgeFlow is a community-created addon that brings advanced edge manipulation tools to Blender. It is particularly useful for fixing topology on curved surfaces where manually adjusting vertices would destroy the smooth curvature.

It essentially allows you to "relax" edges so they flow naturally between their neighbors.

Key Features​

Set Flow

Adjusts the selected edges to fit the curvature of the surrounding geometry. Like a "smooth" brush but mathematically precise for loops.

Set Linear

Straightens the selected edge loop into a line between its endpoints.

Set Curve

Fits the selected edges to a spline curve, creating perfectly smooth organic shapes.

Installation​

This is an external addon:

  1. Download the ZIP file from the GitHub Repository.
  2. Open Edit > Preferences > Add-ons.
  3. Click Install... and select the downloaded ZIP.
  4. Enable Mesh: EdgeFlow.

Usage​

  1. Select an edge loop or a series of edges in Edit Mode.
  2. Right-click to open the context menu.
  3. Navigate to the EdgeFlow menu at the bottom.
  4. Select Set Flow, Set Linear, or Set Curve.

Tip: You can also access these commands via the Ctrl+E (Edge) menu.

Visual Investigation Use Cases​

  • Vehicle Modeling: Cleaning up topology on car hoods or fenders where reflections need to be perfect.
  • Organic Shapes: Smoothing out edge loops on character models or organic evidence (e.g., clothing folds).
  • Topology Repair: Fixing "pinched" or uneven geometry after boolean operations or manual stitching.
