python cad 二次開發

from pyautocad import Autocad, APoint
import win32com.client
from win32com.client import VARIANT
from win32com.client import Dispatch
import pythoncom

要么用pyautocad這個，要么用win32com

cad不識別直接傳過去的坐標，需要轉換下，以下是關鍵代碼

def vtpnt(x, y, z=0):
    """坐標點轉化為浮點數"""
    return VARIANT(pythoncom.VT_ARRAY | pythoncom.VT_R8, (x, y, z))


def vtobj(obj):
    """轉化為對象數組"""
    return VARIANT(pythoncom.VT_ARRAY | pythoncom.VT_DISPATCH, obj)


def vtFloat(list):
    """列表轉化為浮點數"""
    return VARIANT(pythoncom.VT_ARRAY | pythoncom.VT_R8, list)


def vtInt(list):
    """列表轉化為整數"""
    return VARIANT(pythoncom.VT_ARRAY | pythoncom.VT_I2, list)


def vtVariant(list):
    """列表轉化為變體"""
    return VARIANT(pythoncom.VT_ARRAY | pythoncom.VT_VARIANT, list)

 下面是如何啟動autocad2007，其他的自己試吧

if __name__ == '__main__':
    # AutoCAD2007 ProgId is "AutoCAD.Application.17"
    acad = Dispatch("AutoCAD.Application.17")
    doc = acad.ActiveDocument
    doc.Utility.Prompt("Hello AutoCAD\n")
    mp = doc.ModelSpace
