Fusion360APIでNURBS曲線を作成してみる3 - C#ATIA
Line Arc Nurbsの各種入ったIgesをこちらにUpしました。
GrabCAD - CAD library
（ファイル名：nurbs_curve_3d_sample1.igs）
閉じた円弧はArc3Dでは都合悪いかも知れませんが（未テスト）
siren側で2つの開いた円弧に分割しているような気がするので後回し。
Nurbs以外の曲線が現実的に存在しているものか不明なので無視。
一応途中ですが、こんな感じです。
実は円弧に苦労しています。
ｺｰﾄﾞは全く駄目なものですが、自宅で続きをやるかもしれないので記載。

本当は・・・拡張ﾒｿｯﾄﾞ作れそうだからその方法かな？
