Pythonを使用してFreeCADで単純な柱を作成し、.stlファイルとしてエクスポートしたいと思います
私はこれまでに何をしましたか？
円柱（パーツ）を作成し、それを stl ファイルとしてエクスポートするマクロを記録しました。
マクロのテキストをコピーして、「pillar.py」という名前の Python ファイルに貼り付けます。
コードは次のとおりです。
# -*- coding: utf-8 -*-
+++++++++++++++++++++++++++++++++++++++++++++++++
import FreeCAD
import Part
import Mesh
App.ActiveDocument.addObject("Part::Cylinder","Cylinder")
App.ActiveDocument.ActiveObject.Label = "Cylinder"
App.ActiveDocument.recompute()
__objs__=[]
__objs__.append(FreeCAD.getDocument("Unnamed").getObject("Cylinder"))
Mesh.export(__objs__,u"C:/Users/totyped/Desktop/pillar_2.stl")
del __objs__
+++++++++++++++++++++++++++++++++++++++++++++++++
GUI を閉じてターミナルを開き、次のように入力します。
"C:\Program Files\FreeCAD 0.18\bin\FreeCADCmd.exe" "C:\Users\totyped\Documents\pillar.py"
ソース: https://forum.freecadweb.org/viewtopic.php?t=23869
結果:これは端末に表示されるだけで、stl ファイルは作成されません。
また、警告やエラーメッセージも表示されません...
ノート
それで、スクリプトファイルをFreeCADmd.exeと同じディレクトリに置くとうまくいくことに気づきました。なんで ？私は見当もつかない。
編集
@sliptonic の提案に従って、スクリプト ファイルを次のように変更しようとしました。
import FreeCAD
import Part
import Mesh
App.newDocument("Unnamed")
App.ActiveDocument.addObject("Part::Cylinder","Cylinder")
App.ActiveDocument.ActiveObject.Label = "Cylinder"
App.ActiveDocument.recompute()
__objs__=[]
__objs__.append(FreeCAD.getDocument("Unnamed").getObject("Cylinder"))
Mesh.export(__objs__,u"pillar_2.stl")
del __objs__
しかし、私はまだシリンダーを手に入れませんでした。おそらくログファイルが役立つでしょうか？ここにあります：

FreeCAD GUI内からマクロとして実行すると、動作して.stlシリンダーが作成されるため、奇妙です。
