cad坐标怎么输出到excel

要将CAD坐标输出到Excel，可以使用Python的第三方库`ezdxf`和`openpyxl`。以下是具体步骤：

1. 安装所需库：

```bash

pip install ezdxf openpyxl

```

2. 使用以下代码将CAD坐标输出到Excel：

```python

import ezdxf

from openpyxl import Workbook

# 加载CAD文件

def load_cad_file(file_path):

doc = ezdxf.readfile(file_path)

modelspace = doc[0].modelspace

return modelspace

# 将CAD坐标添加到工作表中

def add_cad_coordinates(sheet, modelspace, row, column, x, y):

sheet[row][column] = x, y

# 将数据写入Excel文件

def write_to_excel(file_path, data):

workbook = Workbook()

sheet = workbook.active

for row in range(data.shape[0]):

for col in range(data.shape[1]):

if data[row, col] is not None:

sheet.cell(row=row, column=col).value = data[row, col]

workbook.save(file_path)

# 主函数

def main():

input_file = "input.dwg"

output_file = "output.xlsx"

modelspace = load_cad_file(input_file)

data = []

for row in range(modelspace.layers[0].entities[0].numpoints + 1):

for col in range(modelspace.layers[0].entities[0].numpoints + 1):

if row == 0 and col == 0:

continue

coordinates = (modelspace.points[row][col].x, modelspace.points[row][col].y)

data.append(coordinates)

write_to_excel(output_file, data)

if __name__ == "__main__":

main()

```

3. 运行上述代码，输入CAD文件路径（例如：`input.dwg`），输出Excel文件路径（例如：`output.xlsx`）。请确保输入的CAD文件格式为DWG或DXF。
