【python】【cad】在当前活动的cad界面中使用pyautocad绘制图形

代码

from pyautocad import Autocad, APoint

def create_rectangle(layer_name, pt1, pt2):
    # 初始化AutoCAD应用程序
    acad = Autocad()
    acad.prompt("Hello, Autocad from Python\n")

    # 检查图层是否存在，如果不存在则创建
    layer = None
    for lyr in acad.doc.Layers:
        if lyr.Name == layer_name:
            layer = lyr
            break

    if layer is None:
        layer = acad.doc.Layers.Add(layer_name)

    # 设置当前图层
    acad.doc.ActiveLayer = layer

    # 定义矩形的四个顶点
    pt3 = APoint(pt1.x, pt2.y)
    pt4 = APoint(pt2.x, pt1.y)

    # 绘制矩形的四条边
    acad.model.AddLine(pt1, pt3)
    acad.model.AddLine(pt3, pt2)
    acad.model.AddLine(pt2, pt4)
    acad.model.AddLine(pt4, pt1)

if __name__ == "__main__":
    layer_name = "PYTHON"
    pt1 = APoint(0, 0)
    pt2 = APoint(10000, 10000)
    create_rectangle(layer_name, pt1, pt2)

绘制完成
