Change the dynamic property of a bloc using python

[Grimoult]

Hello everyone,

 

(This is my fist post ever, so don't hesitate to ask me more information if needed) 

 

I'm trying to write a python code to modify a dynamic property of a bloc outside of AutoCAD with python. Here are some information:

- The bloc name is "MESH_RECT". It is a rectangle with a dynamic parameter WIDTH and LENGTH

 

- The dynamic parameter I want to modify is named "WIDTH"

 

- I want to write a python code which would be able to insert the bloc and define width value to the value X (3 for example)

 

 

I manage to insert the block, but can't modify the parameter width. Here is the python code I have started: 

 

import pyautocad


acad = pyautocad.Autocad()
doc = acad.ActiveDocument
ms = doc.ModelSpace

insertion_point = pyautocad.APoint(0, 0)
inserted_block = ms.InsertBlock(insertion_point, "MESH_RECT", 1000, 1000, 1000, 0)  

print(inserted_block.hasattributes)

if inserted_block.IsDynamicBlock:
    # Iterate through dynamic properties
    dynamic_properties = inserted_block.GetDynamicBlockProperties()
    if dynamic_properties:
        for prop in dynamic_properties:
            print(f"Property: {prop.PropertyName}, Value: {prop.Value}")
            if prop.PropertyName == "Width":
                prop.Value = 3

    else:
        print("No dynamic properties found.\n")

 

 

 

Thanks in advance for your help !
