X Mirror¶
The X Mirror option of the Mesh Options panel allows you to edit symmetrical vertices on the other side of the mesh in a single action. When you transform an element (vertex, edge or face), if there is its exact X-mirrored counterpart (in local space), it will be transformed accordingly, through a symmetry along the local X axis.
Nota
The conditions for X Mirror to work are quite strict, which can make it difficult to use. To have an exact mirrored version of a (half) mesh, it’s easier and simpler to use the Mirror Modifier.
Espelhar topologia¶
Nota
Para que a opção Espelhar topologia funcione, a opção Espelhar em X deve ser habilitada.
When using the X Mirror option to work on mirrored Mesh Geometry, the vertices that are mirrored must be perfectly placed. If they are not exactly positioned in their mirror locations then X Mirror will not treat those vertices as mirrored.
A opção Espelhar topologia tenta resolver este problema determinando quais vértices serão espelhados não somente pela utilização de suas posições mas também pela pesquisa de como estes vértices estão relacionado aos outros na geometria da malha. Ela pesquisa na topologia em gera para determinar se os vértices em particular serão tratados como espelhados. O efeito disto é que os vértices espelhados poderão ser não totalmente simétricos ou não simétricos e ainda assim, ser tratados como espelhados quando as opções Espelhar em X e Espelhar topologia estão ambas ativas.
Nota
The Topology Mirror functionality will work more reliably on mesh geometry which is more detailed. If you use very simple geometry, for example a Cube or UV Sphere, the Topology Mirror option will often not work.
Exemplo¶
Por um exemplo de como utilizar corretamente a opção Espelhar topologia, aba uma nova cena do Blender, e então apague o cubo padrão e adicione um objeto do tipo Macaco (Suzanne) para a janela de visualização 3D.
- Pressione o atalho Tab para colocar o objeto de macaco no Modo de edição.
- With the X Mirror option disabled move one of the Monkey object’s vertices slightly.
- Then Turn X Mirror option on again but leave Topology Mirror disabled.
- If you now move that vertex again X Mirror will not work and the mirrored vertices will not be altered.
- If you then enable Topology Mirror and move the same vertices again, then X Mirror should still mirror the other vertex, even though they are not perfectly positioned.
Auto Merge¶

When the Auto Merge option is enabled, as soon as a vertex moves closer to another one than the Threshold setting, they are automatically merged. This option affects interactive operations only (tweaks made in the Adjust Last Operation panel are considered interactive too). If the exact spot where a vertex is moved contains more than one vertex, then the merge will be performed between the moved vertex and one of those.
- Auto Merge
Enables the Auto Merge feature.
- Split Edges & Faces
- Detects the intersection of each transformed edge, creating a new vertex in place and sectioning the edge.
- Threshold
- Defines the maximum distance between vertices that are merged by the Auto Merge.
