# How to create a quad mesh

## Objective:

Export a quadrangulate mesh (a mesh made up of quadrilaterals) by remeshing a triangular mesh.

## Applies to:

* Quad Mesh

## Procedure:

**1.** **Surface Mesh:** Create the surface mesh using the **Mesh from Implicit Body** block.

* [How to mesh complex parts](/help-articles/knowledge-base/meshing-workflows/how-to-mesh-complex-parts)

**2.** **Refine Mesh:** Refine your mesh using **Remesh Surface**, **Simplify by Threshold**, **Simplify by Amount,** or other simplification methods. This step allows for more straightforward conversion to a quad mesh. Make sure your mesh has no [meshing errors](/help-articles/knowledge-base/meshing-workflows/input-mesh-must-be-manifold) in it. Take a look at these articles for tips on refining and creating a mesh:

* [Methods for refining meshes](/help-articles/knowledge-base/meshing-workflows/methods-for-refining-meshes)

**3. Quad Mesh:** Convert the refined **Mesh** to a quad mesh using the **Quadrangulate Mesh** block. The quad mesh allows easier and faster conversion to a CAD Body format.

* A quad mesh is not just a step for converting but is also a very beneficial model.
* [Cell Map on Quad Mesh](https://support.ntop.com/hc/en-us/articles/1500003847722) is used to generate a lattice structure that is conformal to the quad mesh.
* [Check out this article](/help-articles/knowledge-base/interop/quadrangulate-mesh-fails-when-meshing-my-lattice) if you encounter errors when converting to a Quad Mesh.

<Tip>
  **Tip:** Use a **Refine Mesh** block to refine the Quad Mesh, capture further details, and reduce the amount of rounding near sharp edges.

**4..** **Export:** Add an **Export Mesh** block and choose your save location and file type: STL, OBJ, 3MF, or PLY.

And that's it! You've successfully exported your part as a quadrilateral mesh.
