この.csvファイルをFusion360で読み込んでみる

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
