Running functions that takes in symbol as input

[JonathanHandojo]

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?

[CEXT-Dan]

the function should return a tuple with the min max values.
I think you call the entity.GetBoundingBox() with no arguments

``Yea, I tried that, it returned an error of ctypes.COMError: (-2147352562, 'Invalid number of parameters.', (None, None, None, 0, None))

The snippet is:

from pyautocad import Autocad

acad = Autocad()
adoc = acad.ActiveDocument
ent = adoc.HandleToObject("15E88")  ## <--- an object that exists

gb = ent.GetBoundingBox()

Edit: Further to this, I tried the below as well, and this returned Variable 'll': None, 'ur': None, 'gb': None:

from pyautocad import Autocad

acad = Autocad()
adoc = acad.ActiveDocument
ent = adoc.HandleToObject("15E88")  ## <--- an object that exists

ll = None
ur = None
gb = ent.GetBoundingBox(ll, ur)
print('Variable \'ll\': %s, \'ur\': %s, \'gb\': %s' % (ll, ur, gb))

Yeah, I couldn’t get it to work.
As part of my project, https://github.com/CEXT-Dan/PyRx
See https://github.com/CEXT-Dan/PyRx/blob/main/PyRxStubs/AxApp24.py

I used win32com’s makepy to generate wrappers, and that works.
I modified the generated wrappers in that I added in a sequence to variant, as needed.

If you can’t use my project, maybe it will give you inspiration

        util: Ax.IAcadUtility = doc.Utility
        result = util.GetEntity("\nPick an ent: ")
        ent: Ax.IAcadEntity = result[0]
        print(ent.ObjectName, ent)
        print(ent.GetBoundingBox(), ent)
    except Exception as err:
        traceback.print_exception(err)

Wow... I haven't tried it yet, but just by looking at it, that's a very impressive project. I'll follow the steps to install this and give it a shot. I'll let you know how I go. Thanks!

Hi Dan,

I tried installing PyRx, but I can't seem to import its libraries. Upon running the installation, it says 'Python not found', even though I have it installed.

[CEXT-Dan]

If the installer is complaining, you can double check that python is in your path(s)
Before running the installer, make sure the python has a path

BTW, I’ll be out of of touch for the holidays, I fly out in the morning.. kind of bad timing

There’s a ton of info at the swamp that may help you.. kind of a history of my progress and a bunch of samples

Hi, no worries, have a good holiday.

I finally got the modules loaded. However, I wasn't sure from which theApp was referring to.

I made it as such, but still yields an error:

from pyautocad import Autocad
import AxApp24 as Ax

def PyRxCmd_GetEntX():

    acad = Autocad()
    try:
        doc: Ax.IAcadDocument = acad.ActiveDocument
        util: Ax.IAcadUtility = doc.Utility
        result = util.GetEntity("\nPick an ent: ")
        ent: Ax.IAcadEntity = result[0]
        print(ent.ObjectName, ent)
        print(ent.GetBoundingBox(), ent)
    except Exception as err:
        print(err)

PyRxCmd_GetEntX()

Unless I'm misunderstanding something... but I'll continue to investigate and try again.

[CEXT-Dan]

Great! you can just get rid of the pyautocad import and stuff

You can try my test
https://github.com/CEXT-Dan/PyRx/blob/main/PySamples/ActiveX/testWin32Com.py

in AutoCAD, use the new pyload command, load testWin32Com.py
and type GetEntX

let me know how that works.
