Earns its place in the Blender extensions library as a focused, lightweight curve tool at 17.0 KB, with a reversible fillet workflow and no special permissions required.
NURBS/Poly Fillet Tool adds a small context menu in edit mode for curves in Blender. To use it, select a control point at the corner of a path, right-click, and choose 'Filet Helper > Fillet Curve Points' at the bottom of the menu to add a fillet. The add-on covers both fillet and unfillet operations for paths.
The fillet operation is destructive, but it can be reversed. Select the points the fillet created, right-click, and choose 'Filet Helper > Merge Points at Segment Intersection' to turn them back into a single point and start over. Both actions live in the same context menu.
The current version is 1.0.0, published in January 2026 as the initial release. It's compatible with Blender 4.2.5 LTS and newer, weighs 17.0 KB, requires no special permissions, and is distributed under the GNU General Public License v3.0 or later. Installation is by drag and drop into Blender, or by downloading and installing from disk.
NURBS/Poly Fillet Tool is best for blender users who want to add and remove fillets on curve path corners from within edit mode.
NURBS/Poly Fillet Tool is completely free to download and use.
NURBS/Poly Fillet Tool is compatible with Blender 4.2.5 LTS and newer. It works in edit mode for curves, adding a small context menu reached by right-clicking after selecting a control point at the corner of a path. If you're on an earlier Blender release, update to 4.2.5 LTS or later before installing. The add-on is a compact 17.0 KB and requires no special permissions, so it sits lightly alongside your other extensions. The current version is 1.0.0, published in January 2026.
NURBS/Poly Fillet Tool can be installed by dragging and dropping it into Blender, or by downloading the file and using Install from Disk in Blender's extensions preferences. Once installed, it adds a context menu in edit mode for curves. To use it, select a control point at the corner of a path, right-click, and choose 'Filet Helper > Fillet Curve Points' at the bottom of the menu. The add-on is 17.0 KB and asks for no special permissions during setup.
NURBS/Poly Fillet Tool performs a destructive fillet operation, but it offers a way back. After filleting, select the points the fillet created, right-click, and choose 'Filet Helper > Merge Points at Segment Intersection' to turn them back into a single point and start over. This lets you rework a corner rather than permanently locking in the result. Both the fillet and merge actions live in the same context menu available in edit mode for curves.
