最左边的物体make2d结果出现箭头

那個圓管不曉得有什麼問題，會產生有箭頭的曲線，我把你的模型抽出幾個物件回報給我們的工程師處理，謝謝。

@anon667555

我們的工程師說，那個圓管的屬性裡的確有雙向箭頭，所以 Make2D 的結果會有雙向箭頭。

Rhino 無法在曲面物件的屬性加入雙向箭頭，請問你模型裡的那個圓管是怎麼來的?

我忘记模型怎么样了。  
圆管应该是GH提取出来的

物件屬性裡的箭頭是 grasshopper 在 bake 那個圓管的時候加入的，或許 grasshopper 不該把箭頭加入不支援箭頭的 Rhino 物件，等 David Rutten 看看這個問題，謝謝。
