安装dxf模块后，就可以用python 画图，生成dxf文件。
下面是我写的一个示例，用来画很多个不相交的、大小和位置都随机的圆构成的多孔图形。
代码语言：javascript复制import sdxf as s
import random
from random import random, randint
d = s.Drawing()
d.append(s.Text('圆的世界!', point=(0, 105, 1)))
# d.append(s.Line(points=[(0, 0, 0), (1, 1, 1)])) # 画线段
c0, r0 = (0, 0, 0), 100 # 外围大圆的中心和半径
# d.append(s.Arc(center=c0, radius=r0, startAngle=0.0, endAngle=90)) # 画圆弧
d.append(s.Circle(center=c0, radius=r0)) # 画圆
siblings = [] # 格式[((x1,y1,z1),r1),((x2,y2,z2),r2)...]
r_lsl, r_usl = 3, 15
xy_lsl, xy_usl = -100, 100
i = 0
j = 0
while i <= 1000 and j <= 100000:
r = randint(r_lsl, r_usl)
center = xy_lsl (xy_usl-xy_lsl)*random(), xy_lsl (xy_usl-xy_lsl)*random(), 0
# 需在大圆内部
dx = center[0] - c0[0]
dy = center[1] - c0[1]
if dx*dx dy*dy >= (r0-r)*(r0-r):
continue
# 需在所有小圆的外面
for circle in siblings:
dx = center[0] - circle[0][0]
dy = center[1] - circle[0][1]
if dx*dx dy*dy <= (circle[1] r)*(circle[1] r):
break
else:
d.append(s.Circle(center=center, radius=r))
siblings.append((center, r))
print(f"r= {r}, center= {center}")
i = 1
j = 1
d.saveas(r'k:circle world.dxf')
# help(s)该python代码生成的dxf文件在CAD中打开的效果如下：
