If you "join" two surfaces by merging them together into a single mesh (such as joining two halves of a symmetric object), you typically want them to become a single surface, not just two surfaces that happen to be next to each other in space. This has a big impact on rendering, particularly when rendering your model as a subdivision surface. The Weld modifier joins two-or-more surfaces by discarding any "overlapping" points, and "stitching together" the adjacent polygon edges.


  • Apply Weld to a mesh that needs to have boundaries joined.
  • Adjust the Distance property so that Weld can correctly distinguish overlapping points.

Tips & Tricks

See the Symmetric Modeling Tutorial for a detailed example of where to use Weld.
