# Merge Graphs
***
## About this Block
**What it does:** The **Merge Meshes** block merges multiple meshes into a single mesh.
**Common uses:**
* Combining multiple meshes into a single mesh.
**Tips:**
* Adjacent nodes from the meshes will not be shifted or combined, and connectivity will not be assigned between nodes from separate meshes.
* Adjacent nodes can be merged using **Collapse Mesh Vertices**, and the **Remesh Surface** block can redefine the connectivity of a mesh for downstream use.
* Different methods for refining meshes: ([https://support.ntopology.com/hc/articles/360061372374](https://support.ntopology.com/hc/articles/360061372374))
* How to export multiple mesh objects as a single STL: ([https://support.ntopology.com/hc/articles/1500002149622](https://support.ntopology.com/hc/articles/1500002149622))
