Ax.AcadBlockReference.dynamicBlockProperties ZWCAD

[gswifort]

Should this work on ZWCAD? or is dynamic block properties support only available in AutoCAD?

bref: Db.BlockReference = ...
ax_bref = Ax.AcadBlockReference.cast(bref.objectId().acadObject())
ax_bref.dynamicBlockProperties()

#

RuntimeError: 
Exception! Object is NULL, in function GetDynamicBlockProperties, Line 4728, File PyAcadEntityImpl.cpp:

seems to work

from pyrx import Rx, Ge, Gi, Db, Ap, Ed, Ax, command

#M:\Dev\Projects\PyRxGit\PySamples\dwg\dynamicBlock.dwg

@command
def xdoit():
    ps, id, _ = Ed.Editor.entSel("\nSel", Db.BlockReference.desc())
    axRef = Ax.AcadBlockReference.cast(id.acadObject())
    if axRef.isDynamicBlock():
        props: list[Ax.AcadDynamicBlockReferenceProperty]  # hint
        props = axRef.dynamicBlockProperties()
        for prop in props:
            print(prop.value())

Just a note, you should not mix Db and Ax if the object is opened, otherwise it’s undefined behavior.
Ax opens and closes on every function call, possibly changing the state of the DbObject

Make sure bref is closed or garbage collected before getting ax_bref

This is a flaw in AutoCAD’s .net API because your forced to have the Db object opened kForead to get the AcadObject, then all ‘set functions fail because the object is opened kForread

hope that makes sense

Yes, I just figured that out - I had an object open in write mode somewhere else.
Thanks!
