EdgeFlow earns a place in the blender_extensions library for its Set Flow operator, which brings a set-flow style tool common in many 3D applications to Blender's edge loop workflow.
EdgeFlow adds a set of operators to Blender for dealing with curved-shaped meshes. Its core functionality works with edge loops, though a couple of tools operate on vertex selections too. The main tool is Set Flow, which fits an edge loop to the curvature of the surrounding mesh using spline interpolation, adjusting the loop so it respects the flow of neighbouring geometry.
Alongside Set Flow, the add-on includes Set Linear, which straightens each selected edge loop into a line between its start and end while spacing points evenly or projecting from the original distances; Set Curve, which bends an edge loop onto a spline controlled by its first and last edge; and Set Vertex Curve, which moves vertices onto a curve based on the selection order, so two points form a half circle, three fit a circle, and four or more project onto a spline. Options such as Mix, Tension and Iterations tune the results.
The operators are reached from the 3D View via the Mesh > Edge and Mesh > Vertex menus, the right-click context menus, or the Ctrl-E / Ctrl-V shortcuts. Set Flow uses a hermite interpolation with a tension variable.
EdgeFlow is best for modelers adjusting edge loops and vertices to fit curved-surface geometry in Blender.
EdgeFlow is completely free to download and use.
EdgeFlow lists compatibility with Blender 4.2 LTS and newer on the Blender extensions marketplace, so it runs on 4.2 and later releases. Version 1.1.2 included a fix for the Set Vertex Curve operator on Blender 4.4. The developer's GitHub notes the add-on should also work from Blender 3.5 onward and in the current Blender release. Compatibility can shift between versions, so for the current supported range check the developer's page or the marketplace listing before installing.
EdgeFlow installs from a downloaded zip. Get the latest EdgeFlow.zip release from the developer's page, then start Blender and open the user preferences. Switch to the Add-ons tab, click the 'Install...' button, locate the downloaded EdgeFlow.zip file and double-click it to install. Search for the add-on "EdgeFlow" and activate it by ticking the checkbox, hitting Save User Settings at the bottom if your Blender is set up that way.
EdgeFlow's operators are accessed from the 3D View. You can find them in the Mesh > Edge and Mesh > Vertex menus, through the corresponding right-click viewport context menus, or via the default Ctrl-E and Ctrl-V shortcuts. The edge loop tools such as Set Flow, Set Linear and Set Curve work on edge loop selections, while Set Vertex Curve works on vertex selections, where the picking order of the chosen vertices defines the outcome. Each tool then exposes its own settings, such as Mix, Tension and Iterations, to refine the result.
EdgeFlow is listed as free here and is released under the GNU General Public License v3.0 or later. The extension does not require special permissions, according to its marketplace listing. EdgeFlow is maintained by Benjamin Sauder, with additional contributions credited to IngoClemens and ora-0. For the current licensing terms, source code, issue reporting and the latest release, see the developer's page on GitHub. Pricing and availability can change, so confirm the current terms there rather than relying on this listing alone.
