Question

我有一个长管，有几个垂直于管表面的微小圆柱体。我一直在尝试编写一个脚本，使用布尔修饰符将所有内容组合在一起，然后移除微小的圆柱体，这样只有一个网格由一个带有微小圆柱体的管组成（对于未来的FEA）。创建这些柱面后，我保存了这个搅拌器文件，最后一个柱面处于活动状态。之后，无论我做了什么，我似乎都无法取消选择最后一个圆柱体（如图中i can't seem to get rid of the orange dot, which i thought it was fine but it weren't所示）。因此，当我尝试运行以下代码时：

import bpy  
import bmesh
import mathutils 

bpy.ops.object.select_all(action='DESELECT')

# tried to rename the first cylinder, but the last cylinder was renamed instead
bpy.ops.object.select_pattern(pattern = 'Cylinder')
bpy.context.object.data.name = 'Cylinder.000'

bpy.ops.object.select_all(action='DESELECT')
bpy.ops.object.select_pattern(pattern = 'Cylinder.000')

# tried to remesh the first cylinder, but the last one was remeshed instead
bpy.ops.object.modifier_add(type='REMESH')
bpy.context.object.modifiers["Remesh"].scale = 0.5
bpy.ops.object.modifier_apply(apply_as='DATA', modifier="Remesh")

bpy.ops.object.select_all(action='DESELECT')
bpy.ops.object.select_pattern(pattern = 'tube')

# tried to combine the first cylinder and the tube, but two cylinders were combined instead
bpy.ops.object.modifier_add(type='BOOLEAN')
bpy.context.object.modifiers["Boolean"].object = bpy.data.objects['Cylinder.000']   
bpy.context.object.modifiers["Boolean"].operation = 'UNION'
bpy.ops.object.modifier_apply(apply_as='DATA', modifier="Boolean")

# reselect the first cylinder and delete it (the only one worked!!!)
bpy.ops.object.select_all(action='DESELECT')
bpy.ops.object.select_pattern(pattern = 'Cylinder.000')
bpy.ops.object.delete()

Answer 1

我知道这是一个老帖子，但对于其他想要取消选择所有对象的人，我会这样做：

for obj in bpy.data.objects:
    obj.select = False

Answer 2

Dfelinto向我展示了一个很酷的技巧，让所有物体都成为活跃的。

Answer 3

这是2.8的更新，它减少了对选定对象的迭代。

for obj in bpy.context.selected_objects:
    obj.select_set(False)

或者您可以致电

bpy.ops.object.select_all(action='DESELECT')

无法在Blender中完全取消选择所有对象（使用脚本或密钥A）
