How to export multiple mesh objects as a single STL


When trying to export an STL file from nTop, it may be necessary to export a multibody part as a single *.stl file. 

Applies to:

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


  1. Convert the separate objects to Mesh geometry using any workflow that suits your requirements.
  2. Add the Merge Meshes block to your Notebook and pass a Mesh list of multiple objects into the Meshes property.
  3. Export the results as an STL by right-clicking the Merge meshes block and selecting Export, or by adding an Export Mesh block to your Notebook.

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