Triangles to quads
Merge a suitable adjacent triangle pair into a quad. Matching topology and surface conditions determine which pairs can be combined.
Before you start
Use Face Select in mesh edit mode and select neighboring triangles. Conversion needs suitable adjacent pairs; it is not automatic retopology for an arbitrary generated mesh.
Use the operation
Replace suitable triangle pairs with easier-to-edit quads.
- Start with a small area of adjacent triangles whose shared diagonals you want to remove.
- Choose Tris to Quads from the face context menu.
- Inspect which pairs were combined and which triangles remain.
- Continue region by region, using manual connections or dissolves where automatic pairing is unsuitable.
Controls and choices
| Controls | What changes |
|---|---|
| Adjacent pairs | Two triangles must share suitable topology to form one usable quad. |
| Surface compatibility | Geometry and surface conditions influence which pairs can be joined. A remaining triangle is not necessarily an error. |

Before
A triangle pair
After
One quad
Check the result
Look for regular edge flow and quads that follow the intended shape. A four-sided face can still be stretched or non-planar. Do not repeat the command expecting every triangle to disappear; use deliberate topology editing or remeshing for a different overall structure.
