# How to export multiple mesh objects as a single STL

## Objective:

When trying to export a mesh file from nTop, it may be necessary to export a multibody part as a single mesh file.

## Applies to:

* Merge Meshes
* Export Mesh
* STL
* OBJ
* 3MF

## Procedure:

1. Convert the bodies into meshes using a meshing block like our **Mesh from Implicit Body** block.
2. Add the **Merge Meshes block** to your Notebook and insert the meshed bodies. This will combine the individual meshes into a single mesh.
3. Add an Export Mesh block and insert the new merged mesh. This will export the multibody mesh as a single mesh file.

And that's it! You've successfully exported multiple mesh objects with a single STL file.
