I can't run an example file with the following error messages.

Key not found, does the layer Beam_LSection exist in the drawing?

[greenaway0824]

I don't know. I was just trying to run an example.

[CEXT-Dan]

then change to
ine1.layer = "0" #zero

see if it works, all drawings have a zero layer

Also, if your using AutoCAD 2021 or later, you can try this library. Its being maintained

It doesn't work perfectly but works partially and I think I can start from there. Thanks so much.
Is there any manuals or examples I can refer to?

Just the autocad activex documentation. Check out theswamp.org forums for cad programming
