Pycad

Python Extension for AutoCad

Editor/Debuger

简要说明:

Pycad是利用ironpython来实现对CAD.net API的利用,使得大家得以在CAD上面使用Python语言进行编程.

我们致力于适配上AutoDeskCAD/浩辰CAD/中望CAD等主流CAD.

使用方法:

  1. 程序支持AutoCad2013-2020(2014版本以下需安装.Net4.5),将压缩文件下载后解压到任意目录,在AutoCad在用Netload命令选择解压目录中的NFox.Pycad.Acad.dll,同时支持浩辰Cad,对应加载文件为NFox.Pycad.Gcad.dll。

  2. 程序选用vscode作为编辑器,在Cad中键入pye命令,可以自动打开vscode,当然你需要安装vscode,以及vscode的Python扩展(微软)和Pythonv3.7+。

  3. 如果代码修改完成,在Cad中键入pyrb命令可以即时编译python的脚本。

  4. pytest项目有很多例程可以参考。

  5. vscode右下角有一个即时窗口,可以直接在这里键入或者从代码区拷贝代码直接执行看结果

  6. 修改py项目的组织形式,原项目组织形式为包,不能防止同名包覆盖的问题,新的项目组织形式与国际接轨, 根目录可随意命名, 保证目录下有个extension包即可, 该包不可重命名, 不可缺失;项目的data目录可放置数据文件,程序中可使用findfile(filename)获取文件路径;项目的cuix目录可放置Cad的cuix文件用于加载定制的菜单、工具条和Ribbon菜单;重写了发布功能, 命令pyrelease, 可选择多项目一起发布, 完成后会在temp目录下生成一个自解压安装包xxx.Setup.exe;可以在未安装Pycad的机器上安装Pycad的运行版本和开发的项目;pye命令名修改为pyedit。

  7. 调试器基本完成,提供测试,调试流程: 打开Cad->打开pytest项目->按下F5->在Cad中敲命令即可进入调试模式;退出调试只需要点vscode中的断开连接按钮。

  8. 修正发布功能,增加invokeArx模块以调用Arx函数,例子见pytest项目的runtime模块

感谢山人编写的文档,但是改版暂时只能借鉴了,我们一起把他顶出来写新版的吧:)

如果pye命令出现“系统找不到指定的文件”的错误,请在“Pycad\bin”目录下找到配置文件settings.json,修改“editor.path”参数为vscode的安装目录.

使用教程:

基本用法

1、启动命令

  • 打开cad,在命令行输入netload,如果是autocad,请加载 NFox.Pycad.Acad.dll 如果是浩辰cad,请加载 NFox.Pycad.Gcad.dll,
  • 在命令行输入pyedit,系统会提示你打开项目或者创建项目等选项,选择完毕后,程序自动打开vscode,如果没有安装vscode,请自行安装vscode。
  • 编写完命令后,输入pyrb进行项目编译。

2、导入模块文件:

from pycad.runtime import *
from pycad.system import *

3、开始第一个程序:hello world

@command()
def test(doc)
    print("hello world")
  • 第一行 @command():代表下面定义的函数是个命令函数。命令名称是test, doc是传入参数,是当前主文档对象,如果不太理解的话。可以用下面方法调试查看
@command()
def test2(doc):   
    print "the type is :" , type(doc)
    print "the dwg name is :" , doc.Name
    args=dir(doc)
    for val in args:
         print "the doc object has method or propertyname is :", val

Autocad对象

pycad主要对objectarx.net的二次封装,在system与runtime中,封装了下面的对象:

"acap": "Autodesk.AutoCAD.ApplicationServices",
"acdb": "Autodesk.AutoCAD.DatabaseServices",
"aced": "Autodesk.AutoCAD.EditorInput",
"acge": "Autodesk.AutoCAD.Geometry",
"acrx": "Autodesk.AutoCAD.Runtime",
"acws": "Autodesk.AutoCAD.Windows",
"acgi": "Autodesk.AutoCAD.GraphicsInterface",
"acgs": "Autodesk.AutoCAD.GraphicsSystem",
"acin": "Autodesk.AutoCAD.Internal",
"acps": "Autodesk.AutoCAD.PlottingServices",
"acco": "Autodesk.AutoCAD.Colors",

编写方式跟c#二次开发差不多

图形的创建方法:

@command()
def enttest(doc):
    with  dbtrans(doc) as tr:
        btr=tr.opencurrspace()  #这里默认只读打开,.netapi推荐对象打开先以读打开以节省资源,再需要写入时提权

        #创建点
        point=acdb.DBPoint(acge.Point3d(2,2,0))
        tr.addentity(btr,point)  #addentity会将btr提权为写打开,并将对象加入数据库

        #创建直线 第一个参数:起点  第二个参数:终点
        line=acdb.Line(acge.Point3d(2,2,0),acge.Point3d(4,5,1)) 
        tr.addentity(btr,line)

        #创建圆形 第一个参数:起点 第二个参数:投影向量,第三个参数:半径
        c1=acdb.Circle(acge.Point3d(10,10,0),acge.Vector3d(0,0,1),1)  # z轴投影
        c2=acdb.Circle(acge.Point3d(20,20,0),acge.Vector3d(0,1,0),2)  # y轴投影
        c3=acdb.Circle(acge.Point3d(30,30,0),acge.Vector3d(1,0,0),3)  # x轴投影
        tr.addentity(btr,c1,c2,c3) #or: tr.addentity(btr, *(c1,c2,c3))


        #创建多段线
        pl=acdb.Polyline()
        pl.AddVertexAt(0,acge.Point2d(0,0),0,0,0) #添加顶点
        pl.AddVertexAt(1,acge.Point2d(0,1),0,0,0)
        pl.AddVertexAt(2,acge.Point2d(1,1),0,0,0)
        pl.AddVertexAt(3,acge.Point2d(1,0),0,0,0)
        pl.Closed=True                            #是否闭合
        tr.addentity(btr,pl)

        #创建弧线 第一个参数:弧的圆心 第二个参数:半径 第三个参数: 起点角度 第四个参数:终点角度
        arc=acdb.Arc(acge.Point3d(10,0,0),3,math.pi*0.5,math.pi*1.25)
        tr.addentity(btr,arc)

图层的创建方法:

默认创建图层:


    @command()
    def createlayer(doc):
        LayerName="MyLayer"
        with dbtrans(doc) as tr:
            tr.addlayer(LayerName)
        print("\n创建{0}图层成功".format(LayerName))

添加带颜色的图层


@command()
def cl1(doc):
    LayerName="MyLayer2"
    with dbtrans(doc) as tr:
        tr.addlayer(LayerName,acco.Color().FromColorIndex(acco.ColorMethod.ByLayer,2))               
    print("\n创建{0}图层成功".format(LayerName))

修改图层属性


@command() #修改图层属性
def ModifyLayer(doc): 
    res=edx.entsel("\n选择要修改的图形:")
    if not res.ok(): return
    with dbtrans(doc) as tr:
        ent=tr.getobject(res.ObjectId)  
        ltr=tr.getobject(res.LayerId,acdb.OpenMode.ForWrite) #获取LayerTableRecord表记录
        ltr.IsFrozen=True   #冻结图层
        ltr.IsLocked=True   #锁定图层
        print("\n{0}图层已经冻结和锁定".format(ent2.Layer))

错误类型:

xxx() takes no arguments (1 given)

    @command()
    def cl1(): #这里缺少参数doc,正确写法为 def cl1(doc)
