Helixtoolkitte I need to bend the pipe for this, I have prepared the code for this, but I need xml in ModelVisual3D. The code I've prepared is below. That's not what I want. I want it to come when I click a button. If you have different ways, can you help? A click should form a flat tube and a trapezoid tube.But it does not occur. why not? xaml:
