(2.) Dựa trên các ZXPlane. Sử dụng dòng từ hộp công cụ Draw của tab Phác thảo để tạo ra các dòng. Để vị trí của nó, đặt điểm đầu tiên tại Z = 0 m, X = 0 m và sau đó đặt các điểm thứ hai ở góc gần chính xác, | Tutorial 10 Heating Coil 1. Create a new sketch based on the ZXPlane. 2. Use Line from the Draw Toolbox of the Sketching tab to create the line. To position it place the first point at Z 0 m X 0 m and then put the second point down at approximately the correct angle as shown in the picture below. 3. Now specify the exact angle as follows. Use the Dimensions section of the Sketching tab and choose Angle. Then click on the line and then on the X-axis. If the wrong angle is displayed after you have selected the axis then right-click and choose Alternate Angle until the correct angle is displayed. Click in the Model View to position the angle label.
