Library to make reading, writing and modifying both binary and ascii STL fileseasy.

Project description

Simple library to make working with STL files (and 3D objects in general) fast and easy.

Due to all operations heavily relying on numpy this is one of the fastest STL editing libraries for Python available.

Requirements for installing:

  • numpy_ any recent version
  • python-utils_ version 1.6 or greater

Installation:

pip install numpy-stl

Initial usage:

  • stl2bin your_ascii_stl_file.stl new_binary_stl_file.stl
  • stl2ascii your_binary_stl_file.stl new_ascii_stl_file.stl
  • stl your_ascii_stl_file.stl new_binary_stl_file.stl

Quickstart

from stl import stl

mesh = stl.StlMesh('some_file.stl')
# The mesh normals (calculated automatically)
mesh.normals
# The mesh vectors
mesh.v0, mesh.v1, mesh.v2
# Accessing individual points (concatenation of v0, v1 and v2 in triplets)
mesh.points[0] == mesh.v0[0]
mesh.points[1] == mesh.v1[0]
mesh.points[2] == mesh.v2[0]
mesh.points[3] == mesh.v0[1]

mesh.save('new_stl_file.stl')
