Grasshopper
Improve Arch Truss #02
~ variable radius ~
[ surface > freeform > sweep1 ]
断面形状となるCircleを用意します。
ScaleのFactor要素にSeriesをつないでみました。
スタートの数値は” 1 ”にしています。
断面形状の配置先となるレールを用意してPerpFramesをセットします。
N : ナンバーの入力窓はScaleで使った数値を参照しました。
Orient のAに原点の座標系(平面+基点)の情報を設定して、
Bの接続については配置先の情報としてPerpFramesを使いました。
Loftをつないだ状態です。最後の区間が変化していません。
Seriesを用いて複製した断面の個数とPerpFramesを用いて配置した
仮平面の数が一致していなかったのでSubtractionを用いて調整しました。
配置先のレールを検証用に使っていた直線の形状から曲線に置換えてみました。
おまけ:アーチトラスの部材イメージ
