ImportSplineCSVの使い方
Fusion360を開き，上のタブから「UTILITIES>ADD-INS>Scripts and add-ins...」をクリックする
開いたウィンドウの中から「ImportSplineCSV」を選択し，右下の「Run」をクリックする
エクスプローラーが開くので，先ほど用意した.csvファイルを選択する
翼型のスケッチがインポートされる
ただし，
・後縁が閉じていない（閉曲面になっていないので押し出せない）
・コード長が10㎜（1㎝）になっている
ことに注意する
左のツリーの翼型のスケッチをダブルクリックして編集モードにし，後縁をつなぐような直線を追加する
スケッチの内側が薄い青色になる
ツリーで翼型のスケッチを選択した状態で，上のタブから「SOLID>MODIFY>Scale」をクリックする
倍率を入力できるので，「100」を入力してコード長を10㎜から1000㎜に拡大する
最後に，ツリーで翼型のスケッチを選択した状態でF2キーを押し，名前を分かりやすいように変更する（今回は"NACA0009"）
これで翼型の読み込みは完了である
おわりに
Fusion360でImportSplineCSVを使って翼型の座標ファイルを読み込む方法について説明した
このアドインをちょっといじれば，連番のCSVファイルを読み込んだりもできるようになる
