This Python code reads polygons from a shapefile, converts them to 3D, and converts them to an STL file. I created this python code for the purpose of making a Japanese city puzzle.

Shapeファイルからポリゴン抽出を行い、Z方向に押し出して、3Dプリンタで使用できるSTLファイルに変換します。

python shape2stl.py [shapefile path] [shapeIndex] [scaleFactor] [z offset]

• [shapefile path]
  • This argument specifies the path to the shapefile (.shp format).
• [shapeIndex]
  • This argument specifies an index to select a particular shape.
• [scaleFactor]
  • This argument specifies the value used to scale the polygons. All polygons are normalized from 0 to 1.
• [z offset]
  • This argument specifies the thickness (Z-direction offset). This value is the length of the extrusion in the Z direction.
