Earns its place in the superhive library as a focused, single-purpose add-on for rounding bezier corners in Blender 2.7x, with a modal workflow and a GPL license.
Bezier Curve Fillet Tool is a small Blender add-on from Luxuy Store that converts sharp bezier corners into rounded edges. Modeling with bezier curves usually produces either smooth curves or sharp lines, yet most real-world objects are a mixture of both. Adjusting spline handles by hand to round a corner takes time to get the angles exactly right, and this add-on handles that step with the click of a button.
The tool uses a modal operator, so the result appears in real time. In curve edit mode, you select the corners you want rounded and press W then Bezier Curve Fillet, or use the Ctrl+F hotkey. Moving the mouse sets the fillet radius, and holding Ctrl while moving changes the ratio, with values calculated from the mouse's distance from its initial position.
As of the 2015-06-04 update, a ratio of 1 makes a perfect circular fillet and 0.5 makes a flat chamfer-like fillet. Built for Blender 2.7x and released under the GPL license, it stays focused on one task: turning sharp corners into fillets.
Bezier Curve Fillet Tool is best for blender artists working in curve edit mode who want to round sharp bezier corners into fillets without manually dragging spline handles.
Bezier Curve Fillet Tool is completely free to download and use.
Bezier Curve Fillet Tool is built for Blender 2.7x, where it works as a small add-on for rounding sharp bezier corners into fillets. To activate it, you open the user preferences window, switch to the add-ons tab, find the Add Curve category, and turn on the Bezier curve fillet tool. Because it targets the 2.7x series, artists on newer Blender releases should check the developer's page before relying on it, since compatibility with later versions is not stated here.
Bezier Curve Fillet Tool installs by placing its python file into the scripts/addons/ directory, then pressing F8 to refresh Blender. After that, open the user preferences window, switch to the add-ons tab, and look under the Add Curve category, where you enable the Bezier curve fillet tool. Once it is turned on, the operator becomes available in curve edit mode, so you can select corners and start filleting them right away using the menu or hotkey.
Bezier Curve Fillet Tool works in curve edit mode. Select the corners you want rounded, then press W and choose Bezier Curve Fillet, or use the Ctrl+F hotkey. Because it uses a modal operator, the result shows in real time: moving the mouse adjusts the fillet radius, and holding Ctrl while moving the mouse changes the ratio. The value is calculated from the mouse's distance from its initial position, so you set both radius and ratio interactively as the result updates in real time.
Bezier Curve Fillet Tool controls the shape of each rounded corner through its ratio value, which you adjust by holding Ctrl and moving the mouse. As of the 2015-06-04 update, a ratio of 1 produces a perfect circular fillet, while a ratio of 0.5 produces a flat, chamfer-like fillet. Alongside the radius set with Ctrl+F, this gives you two controls for shaping corners, letting you move between rounded and chamfered results as part of the modal operation.
Bezier Curve Fillet Tool is listed as free in this catalog and is distributed under the GPL license. Licensing terms can change over time, so check the developer's page for the current details before downloading. The add-on targets Blender 2.7x, so it is worth confirming that the version you need matches your setup while you are reviewing the listing and its requirements.
