AutoCAD Automation for Python ⛺

pyautoacad - AutoCAD Automation for Python

This library aimed to simplify writing ActiveX Automation scripts for AutoCAD with Python

Requires:

• comtypes

Optional:

• xlrd, tablib

Features:

• Simplifies work with coordinates (3D points)
• Efficient objects iteration and searching (with casting to correct type)
• Excel/csv/json import and export (xlrd and tablib required)

Simple usage example:

from pyautocad import Autocad, APoint


acad = Autocad()
acad.prompt("Hello, Autocad from Python\n")
print acad.doc.Name

p1 = APoint(0, 0)
p2 = APoint(50, 25)
for i in range(5):
    text = acad.model.AddText('Hi %s!' % i, p1, 2.5)
    acad.model.AddLine(p1, p2)
    acad.model.AddCircle(p1, 10)
    p1.y += 10

dp = APoint(10, 0)
for text in acad.iter_objects('Text'):
    print('text: %s at: %s' % (text.TextString, text.InsertionPoint))
    text.InsertionPoint = APoint(text.InsertionPoint) + dp

for obj in acad.iter_objects(['Circle', 'Line']):
    print(obj.ObjectName)

How to read existing dwg file using autocad??

I studied your tutorial materials.
But most of them are drawing pictures into new file.

How could I open/load/read existing dwg file??

My sorce can run Ok ,but VScode tell me issues

1:L use python 3.8
2:l use pyautocad 0.2.0
3: I use AutoCAD 2023
4:I use windows 11 system
5:My sorce can run Ok ,but VScode tell me issues

PyAutoCAD & Python 2.5

I am getting an attribute error from the initial import of the module. I am using pyautocad 0.1.2, python 2.5.1 & comtypes 0.6.2 on Win7 32Bit system.

Using example

from pyautocad import Autocad, APoint

acad = Autocad()
p1 = APoint(0.0, 0.0)
acad.model.AddCircle(p1, 0.5)

Get the following error;

Traceback (most recent call last):

Is it possible to draw surfaces and Volumes using Pyautocad ?

Hello,

I'm trying to draw several building automatically using python, so far using APoint, line and AddCircle, i'm able to add columns and slabs. But every thing is linear. I wanted to know if there was a way to draw a surface, or Extrude would be PERFECT.

Thank you all for your help :D

pyautocad - windows 8 (64 bits) and AutoCAD 2013

I have a new computer with windows 8 (64 bits) and I installAutoCAD 2013.

I´ve tried a routine that used to work in windows 7 (32 bits) + AutoCAD 2008.....here is the error:

Exception WindowsError: 'exception: stack overflow' in <bound method tagVARIANT.del of VARIANT(vt=0x8, u'Digite ABA da cantoneira: ')> ignored
Exception WindowsError: 'exception: access violation writing 0x0000000000040000' in <bound method BSTR.del of BSTR(None)> ignored

Running functions that takes in symbol as input

I'm just wondering, how can you pass on symbols as arguments here? For example, I very much need to use the GetBoundingBox and GetEntity function, but I can't seem to get this working because both function need to take in a symbol.

Or if this is not possible, then what's the other alternative to solve this?

import dxf from path and paste it on my draw

Hi to everyone,
I'm trying since last week to copy from a directory X:\windows\cad\repo\file_to_import.dxf
and paste to X:\windows\cad\new_file.dxf , but i have to paste the previous (file_to_import.dxf) in a specific layer number and X Y Coordinates.
I cant find how..
In the Docs i dont see some import command or how to write directly in the autocad terminal.
If i can write in the terminal i can do the task..
I dont want someone to write my code, i want to learn the pyautocad's command for do this job.

Thanks to everyone

Read Custom DWGProps

I have been tasked with writing something to read through the custom DWGProps in an AutoCAD drawing. Is this possible using pyautocad?

_ctypes.COMError, need help

Hi reclosedev,
Your lib helps a lot...
And here are 2 question I wand to ask.
The first one is can I save the drawing use acad.doc.save(r'C:\Users\Administrator\Desktop\1.dwg')
or acad.doc.save(r'C:\Users\Administrator\Desktop\1.dwg')?

the example code below:

#!/usr/bin/env python
# -*- coding: utf-8 -*-
from pyautocad import Autocad, APoint

acad = Autocad(create_if_not_exists=True)
acad.prompt("Hello, Autocad from Python\n")
print acad.doc.Name
try:
    acad.doc.save(r'C:\Users\Administrator\Desktop\1.dwg')
except Exception as e:
    print e

The exception show
_ctypes.COMError (-2147352562, '\xce\xde\xd0\xa7\xb5\xc4\xb2\xce\xca\xfd\xca\xfd\xc4\xbf\xa1\xa3', (None, None, None, 0, None))

The second question is how to hatch an object.The doc of ActiveX/VBA gives a VBA code below:

Sub Ch4_AppendInnerLoopToHatch()
    Dim hatchObj As AcadHatch
    Dim patternName As String
    Dim PatternType As Long
    Dim bAssociativity As Boolean

    ' 定义和创建图案填充
    patternName = "ANSI31"
    PatternType = 0
    bAssociativity = True
    Set hatchObj = ThisDrawing.ModelSpace. _
        AddHatch(PatternType, patternName, bAssociativity)

    ' 创建图案填充的外部环
    Dim outerLoop(0 To 1) As AcadEntity
    Dim center(0 To 2) As Double
    Dim radius As Double
    Dim startAngle As Double
    Dim endAngle As Double
    center(0) = 5: center(1) = 3: center(2) = 0
    radius = 3
    startAngle = 0
    endAngle = 3.141592
    Set outerLoop(0) = ThisDrawing.ModelSpace. _
       AddArc(center, radius, startAngle, endAngle)
    Set outerLoop(1) = ThisDrawing.ModelSpace. _
       AddLine(outerLoop(0).startPoint, outerLoop(0).endPoint)

    ' 将外部环附加到 Hatch 对象
    hatchObj.AppendOuterLoop (outerLoop)

    ' 创建一个圆作为图案填充的内部环
    Dim innerLoop(0) As AcadEntity
    center(0) = 5: center(1) = 4.5: center(2) = 0
    radius = 1
    Set innerLoop(0) = ThisDrawing.ModelSpace. _
                                 AddCircle(center, radius)

    ' 将圆作为内部环附加到图案填充
    hatchObj.AppendInnerLoop (innerLoop)

    ' 计算并显示图案填充
    hatchObj.Evaluate
    ThisDrawing.Regen True
End Sub

the code hatchObj.AppendInnerLoop (innerLoop) how to rewrite use python?
Need your help, thanks a lot.

for the following code,
from pyautocad import Autocad, APoint
acad = Autocad(create_if_not_exists=True)
doc = acad.ActiveDocument
def gpuser():
sp = APoint(0, 0, 0) # Initializing sp with coordinates (0, 0, 0)
ep = APoint(0, 0, 0) # Initializing ep with coordinates (0, 0, 0)
rp = APoint(0, 0, 0) # Initializing rp with coordinates (0, 0, 0)
sp = doc.Utility.GetPoint("\nBottom-left corner on the column:")
ep = doc.Utility.GetPoint("\nBottom-right corner on the column:")
rp = doc.Utility.GetPoint("\nTop-left corner on the row:")
print("sp(1) input =", sp[0]) # Assuming you want to print the X coordinate of the 'sp' point
gpuser()
How can I fix the error and to get the correct response from the active autocad drawing.
Thanks in advance,
Sun, Son

Read&Write DWG

There is a task to automate the routine process associated with Autocad 2020 LT. You need to insert the same table into 180 DWG files (it's not a problem to load it in Python). The method for opening the file doesn't work:

from pyautocad import Autocad, APoint
acad = Autocad()
acad.prompt("Hello, Autocad from Python\n")
print(acad.doc.Name)

Help me, please if it possible.

How can i settle this? I need your help.
By the way ,the version of my auto cad is 2018.
Thanks~!

How to convert an image to cad file or vector file using python?

I am new to this and have saw python package pyautocad. Can someone help me out with this? Thanks

why my script doesn't iterate all text objects

Hello, I have a problem, I wrote some script and I want to iterate all the text in my model space and redefine changed texts.

Some texts are not iterated, Some texts iterated two times and rest of them are ok.

you can take script also, I have something like 2000 object for the testing purpose, they are all the same I just want to use this script in the project, I have to renumber chainages and add all of them 0.51m. how can I fix this problem?
I think it is a pyautocad problem, every time when you just iterate texts by regular expression search it skips some text, but only cases when you use obj.Delete() or obj.Move() functions, if you just ask to show all object it will show you all of them, but if you try to change position or delete them it will skip some objects, I think some operations happens quicker then others.

`from pyautocad import Autocad, APoint

from pyautocad import Autocad, APoint
acad = Autocad(create_if_not_exists=True)

L1 = acad.model.AddLine(APoint(0,0), APoint(500,250))
L2 = acad.model.AddLine(APoint(0,100), APoint(500,600))

for obj in acad.iter_objects():
    obj.Delete()

it returns:

COMError                                  Traceback (most recent call last)

I noticed (from AutoCAD) the first object is deleted but not the 2nd one (in the case of two objects).
If I have a lot of objects, some are deleted, and some are not.

It is ok when i do L1.Delete() or L2.Delete(),

Is there anything wrong? Thanks a lot!

How can i open a new drawing with pyautocad?

how to access to all methods and classes of 'pyautocad' library

hello. Iwant to know that how can I access to all methods and classes of 'pyautocad' library?

Incompatible with python 3.x

The library's source files contain syntax incompatible with python 3.x, notably the print statement (when it should be a function). The syntax is otherwise not yet adapted for python 3.x, e.g.: old-style string formatting (the % operator), old-style exception handlers (comma instead of 'as'), and so on. The total amount of corrections to be made for python 3.x support is not so large.

As of version 0.1.3, pyautocad causes syntax errors on python 3.4. Please update the library ASAP.

AddRegion - problem with array

Hi....first I'd like to thanks. This Python connection with AutoCAD is very usefull!!!

My goal is to create a solid.....but before the AddExtrudedSolid I need to create a Region (AddRegion).

The problem is to bulid the array correctly. The examle below is to draw a "L" shape....user must inform the width and tickness.

Thanks again,

Luciano

_ctypes.COMError: -2147467262

Hi Roman,
First of all - thank you so much for this library. It is working great and allows me to do what i wanted just in Python.
I wrote a simple script (with gui) and it worked well on my machine, but after compiling i tried it on two different machines and received an error. Here is a version of the error from each of the machines:

1. _ctypes.COMError: (-2147467262, 'No such interface supported', (None, None))
2. _ctypes.COMError: (-2147467262, '\xfe\xfe\xee\xee\xf9\xf7 \xee\xf1\xe5\xe2 \xe6\xe4 \xe0\xe9\xf0\xe5 \xf0\xfa\xee\xea', (None, None, None, 0, None))

Plot automation

I'm working on a project of plan plotting automation with python, I was able to do it with pywin32 but I couldn't do it with pyautocad. The problem itself is that I need a point of only 2 coordinates for the plotting window, APoint uses three dimensions, is there any alternative to solve this problem?

Point1 and Point 2 must be only x , y coordinates.

Open DWG files and manipulate them

I am trying to figure out if it is possible to open multiple already existing dwg files through pyautocad and manipulate them to create a single dwg file. Basically, I am trying to figure out if I can take various drawings of different length walls and manipulate those walls to create a single room. I am trying to automate this process as each wall is already drawn and it is tedious to pull in each wall every time I go to draw a room. Does pyautocad support something like this? I was unable to find anything in the documentation on opening and manipulating previously created DWG files.

Possible Typo in pyautocad-0.2.0.zip and pyautocad-0.2.0.win32.exe

Just installed the pyautocad (and github to make this issue) this afternoon and when running a test for: data = Table.data_from_file('data.xls')
I kept getting an error message for xrange not existing. It was fixed when I deleted an x within the table.py file on lines 163 and 165. I've never used github so I don't have the experience for proposing actions/fixes but I hope someone can use this information to fix the error for other newcomers like me.

Pyautocad: error using pyautocad library on windows (python 3.8)

Good moning,

I’m trying using pyautocad library in python 3.8 on windows with the following example code taken from a tutorial:
import pyautocad acad = pyautocad.Autocad() print(acad.doc.Name) from pyautocad import APoint point1 = APoint(100.0,100.0) circle1 = acad.model.AddCircle(point1,100) circle1.Color = 10 print("current layer: " + str(circle1.Layer)) print("current linetype: " + str(circle1.Linetype)) print("current linetype scale: " + str(circle1.LinetypeScale)) print("current line weight: " + str(circle1.Lineweight)) print("current thickness: " + str(circle1.Thickness)) print("current material:" + str(circle1.Material)) circle1.Layer = "circles" circle1.Color = 256 circle2 = acad.model.AddCircle(APoint(200.0,200.0),100) circle3 = acad.model.AddCircle(APoint(300.0,300.0),100) for obj in acad.iter_objects(): print(obj)

But I obtain the following error and I don’t understand how to solve it:

python pyAutocadTest.py Traceback (most recent call last): File "pyAutocadTest.py", line 6, in <module> print(acad.doc.Name) File "C:\Users\3bMeteo\anaconda3\lib\site-packages\pyautocad\api.py", line 74, in doc return self.app.ActiveDocument File "C:\Users\3bMeteo\anaconda3\lib\site-packages\pyautocad\api.py", line 63, in app self._app = comtypes.client.GetActiveObject('AutoCAD.Application', dynamic=True) File "C:\Users\3bMeteo\anaconda3\lib\site-packages\comtypes\client\__init__.py", line 180, in GetActiveObject obj = comtypes.GetActiveObject(clsid, interface=interface) File "C:\Users\3bMeteo\anaconda3\lib\site-packages\comtypes\__init__.py", line 1245, in GetActiveObject oledll.oleaut32.GetActiveObject(byref(clsid), None, byref(p)) File "_ctypes/callproc.c", line 948, in GetResult OSError: [WinError -2147221021] Operazione non disponibile

Can I ask if someone has a solution?

Thank you in advance

Best Regard
