# Export Mesh

## About this Block

**What it does:**
The Export Mesh block saves a surface mesh to a specified file path as either an .OBJ, .STL, .PLY, or .3MF file. The length units are specified as an input.

**Common uses:**

* Exporting meshes for use in alternative software or other instances of nTop.

**Tips:**

* Easiest way to export an STL, OBJ, or PLY file.
* For information on all import/export file types: ([https://support.ntopology.com/hc/articles/360048249514](https://support.ntopology.com/hc/articles/360048249514))
* If you are having trouble exporting a complex mesh, consider using Refine Mesh, Simplify Mesh by Amount, or Simplify Mesh by Threshold blocks to reduce the file size. ([https://support.ntopology.com/hc/articles/360061372374](https://support.ntopology.com/hc/articles/360061372374))
