将原点的 X 方向与选定的面法线方向对齐,Python 脚本

问题描述 投票:0回答:0

我不是程序员,我陷入了一个问题,也许有人可以帮助我!使用 AI 代码生成,我制作了这个脚本,其中原点跳到所选面的中心。在这一步之后,我只想将原点的 X 方向与选定的面法线方向对齐。到目前为止,我无法从 AI 生成代码。

我将不胜感激任何帮助或指导。

代码在下面!

import bpy
import bmesh
from mathutils import Vector

def set_origin_to_selected_face():
    # Ensure the object is in Edit mode
    bpy.ops.object.mode_set(mode='EDIT')

    # Get the active object
    obj = bpy.context.active_object

    # Create a BMesh object
    bm = bmesh.from_edit_mesh(obj.data)

    # Get the selected face
    selected_faces = [f for f in bm.faces if f.select]

    if not selected_faces:
        print("No face selected. Please select a face and try again.")
        return

    selected_face = selected_faces[0]

    # Calculate the center of the selected face
    face_center_local = selected_face.calc_center_median()
    
    # Convert the face center from local to world coordinates
    face_center_world = obj.matrix_world @ face_center_local

    # Store the current cursor location and set the cursor to the face center
    cursor_location = bpy.context.scene.cursor.location.copy()
    bpy.context.scene.cursor.location = face_center_world

    # Set the origin to the 3D cursor
    bpy.ops.object.mode_set(mode='OBJECT')
    bpy.ops.object.origin_set(type='ORIGIN_CURSOR')

    # Restore the cursor location
    bpy.context.scene.cursor.location = cursor_location

set_origin_to_selected_face()

enter image description here

希望原点的 X 方向朝向所选面的法线方向。
