Let’s start with modeling
Use the line tool to draw a curve in the top view, with only 3 vertices.
Switch to the editing and modification panel, enter the line subset of the line object, select the line object, hold down the shift key and move up, copy another line segment, switch to the vertex subset of the object, and edit the moving vertices.
Open the lock button at the bottom of the screen, right-click to bring up its setting options, and change it to vertex mode.
Still staying in the subset, press the Create Line button on the panel, click in the view, and connect the vertices. At this time, since vertex adsorption is enabled, the newly created line segment endpoints will automatically adsorb to the desired on the connected vertices. This is done so that the surface command can be used in the next step to perform correctly, because the working principle of surface is that the lines must form a quadrilateral or a triangle.
Close the subset of objects and return to the top layer, add a surface modifier, and voila, the surface has been created! At the same time, you can set the object to be visible on both sides, or simply assign a material to the object, and check Visible on both sides on the object material in the material editor.
At this time, you can adjust the shape or add details according to the specific situation. Just return to the subset of the line state, you can move the vertices, or add points or lines.
Just remember-the line segments must surround a quadrilateral or a triangle, and there are still points between the points. There must be line segments connected.
Adjust it to what you imagine. You should have the windmill blade you want in mind, right?
Enter the hierarchy panel and move the object's axis to its corner.
Select the rotation tool, hold down the shift key to rotate the object (you can press the lock angle button at the bottom of the screen first) 120 degrees, an options window will pop up, select the association method, and the second piece of wind will be copied. leaf. Duplicate the object in the same way until three wind blades appear. With this, the modeling is complete!
