Blender MCP Tooling

搅拌机mcp工具

一个类型化的Python工具包，用于通过MCP生成参数化Blender对象，而无需在迭代之间重置Blender会话。

每种能力都作为 食谱：一个接受类型化规范并返回一个可通过MCP执行的自包含Blender Python脚本的函数。

它看起来像什么

切削刀具托架板

带有布尔切割半瓦孔图案（八角形+菱形+菱形簇）的边框框架。

规格： 317.5×165.1毫米框架·0.75英寸边框·10.58毫米厚·14×6网格·336个贯通孔

看 examples/cutting_tool_carrier_v3.py 对于完整的发电机。

结构件

网格/格子图案

图案拼接和切割

为什么 build_center_pattern_script()? build_repeat_grid_script() 按对象的局部起源放置群集对象。实际的形状顶点（八角形、菱形、菱形控制点）可以相对于世界原点偏离中心几毫米。 build_center_pattern_script() 测量所有POLY样条曲线控制点的真实边界框，并在布尔切割之前对其进行校正。始终在铺瓷砖和切割之间运行。

承载板的标准管道

from blender_mcp_tooling.application.recipes.repeat_grid import build_repeat_grid_script
from blender_mcp_tooling.application.recipes.center_pattern import build_center_pattern_script
from blender_mcp_tooling.application.recipes.boolean_cut import build_boolean_cut_script

# 1. Tile the cutting pattern
exec(build_repeat_grid_script(request, grid, collection_name="CuttingTool_HalfTile"))

# 2. Geometrically centre it on the carrier (corrects cluster-origin offset)
exec(build_center_pattern_script(request, collection_name="CuttingTool_HalfTile"))

# 3. Boolean-cut through the carrier solid
exec(build_boolean_cut_script(
    request,
    target_object_name="CuttingTool_CarrierPlate",
    cutter_collection_name="CuttingTool_HalfTile",
))

快速食谱示例

带角孔的框架

from blender_mcp_tooling.application.recipes.frame import build_frame_part_script
from blender_mcp_tooling.design import FrameHolePattern, FramePartSpec

frame_spec = FramePartSpec(
    outer_width=317.5,
    outer_height=165.1,
    thickness=10.58,
    inner_opening_width=279.4,
    inner_opening_height=127.0,
    border_left=19.05,
    border_right=19.05,
    border_top=19.05,
    border_bottom=19.05,
    hole_enabled=True,
    hole_pattern=FrameHolePattern.CORNERS,
    hole_diameter=5.0,
    part_name="CuttingTool_BorderFrame",
)

script = build_frame_part_script(request, frame_spec)

圆环

from blender_mcp_tooling.application.recipes.ring import build_ring_part_script
from blender_mcp_tooling.design import RingPartSpec, RingShape

ring_spec = RingPartSpec(
    shape=RingShape.CIRCULAR,
    outer_size=(96.0, 96.0),
    thickness=5.0,
    band_width=10.0,
    part_name="Ring_Circle_01",
)

script = build_ring_part_script(request, ring_spec)

通过倒角方形辅助件形成八角形环

from blender_mcp_tooling.design import build_chamfered_square_points, RingPartSpec, RingShape

outer_pts = build_chamfered_square_points(140.0, 140.0, 28.0)
inner_pts = build_chamfered_square_points(98.0, 98.0, 18.0)

ring_spec = RingPartSpec(
    shape=RingShape.CUSTOM_CURVE,
    outer_size=(140.0, 140.0),
    inner_size=(98.0, 98.0),
    thickness=8.0,
    custom_outer_points=outer_pts,
    custom_inner_points=inner_pts,
    part_name="Ring_ChamferedSquare_01",
)

重复网格簇平铺

from blender_mcp_tooling.application.recipes.repeat_grid import build_repeat_grid_script
from blender_mcp_tooling.domain.repeat_grid import EdgeMode, RepeatGridSpec

grid = RepeatGridSpec(
    cluster=cluster_spec,
    cols=14,
    rows=6,
    col_gap=0.5,
    row_gap=0.5,
    edge_mode=EdgeMode.EDGELESS,
)

script = build_repeat_grid_script(request, grid, collection_name="CuttingTool_HalfTile")
