Earns its place in the superhive library by expanding Blender's stock symmetrize with non-destructive reference points, local and global orientation, and an adjustable threshold. A demo video is available.
Advanced Symmetrize adds more control to Blender's symmetrization process. Instead of relying only on the object's origin, it lets you symmetrize from multiple non-destructive reference points: the 3D cursor, the center of the current selection, or the active element, whether that's a vertex, edge, or face. Because you don't have to modify the object's origin, the mesh's rotation and any modifiers that depend on that origin stay intact.
The add-on offers local orientation, which respects the object's orientation, and global orientation, which aligns with the world axes; a cursor orientation option is listed as coming soon. An adjustable threshold defines which vertices are treated as symmetrical, and automatic cleanup removes duplicate faces on the symmetry plane.
It's accessible from the mesh edit menu. To use it, select the elements to symmetrize in edit mode, choose the axis, reference point, and orientation, adjust the threshold if needed, and execute the operator. It runs under the GPL license.
Advanced Symmetrize is best for blender modelers who want to symmetrize from reference points other than the object's origin, with threshold control and automatic cleanup of duplicate faces on the symmetry plane.
Advanced Symmetrize is completely free to download and use.
Advanced Symmetrize lists support for a broad range of Blender releases: 4.3, 4.2, 4.1, 4.0, 3.6, 3.5, 3.4, 3.3, 3.2, and 3.1. That spans both the 3.x line and the more recent 4.x versions, so if you're working in any of those you should be able to install and run it. If you're on a version outside that list, check the developer's page for the current compatibility details before installing.
Advanced Symmetrize is accessible from the mesh edit menu. The basic workflow starts in edit mode: select the elements you want to symmetrize, then choose the axis, the reference point, and the orientation. Adjust the threshold if you need to fine-tune which vertices are treated as symmetrical, then execute the operator. Reference points include the 3D cursor, the center of the current selection, and the active element, so you can symmetrize without changing the object's origin.
Advanced Symmetrize offers local and global orientation. Local orientation respects the object's own orientation, while global orientation aligns the symmetry with the world axes. A cursor orientation option is listed as coming soon. Alongside orientation, you can pick from multiple non-destructive reference points and set an adjustable threshold that defines which vertices are considered symmetrical, giving you control over how the symmetrization is aligned and calculated.
Advanced Symmetrize is listed as free here in the catalog, and it's distributed under the GPL license. Licensing terms can change over time, so for the most current details on pricing and usage rights, head to the developer's page. The GPL license applies to the add-on itself, which is standard for Blender add-ons and covers how you can use, modify, and redistribute the code.
