Few queries:
1. Which format do you want to export to? DXF is anyways a valid format and the functionality is already there in AutoCAD itself
2. Could you please elaborate about what manipulation you require? We can read the DXF format which is an open protocol and manipulate it accordingly.
3. After manipulation do you want to re-import it to AutoCAD?
I am Pranav Patil, representing Iristechsys Software Services LLP, an ISO 9001:2015 company based out of Pune, India.
Our company has a valid DUNS number and is duly registered with Registrar Of Companies, India - just to point out that we are *not* a fly by night operator.
My Linked-In profile will provide you overview of my experience.
In my corporate stint, I was working with the CAD connectors group in Siemens PLM, the company that develops NX CAD modelling software. And by education, I have done my post graduation in Computer aided engineering.
In the past I have worked both on AutoCAD as well as DraftSight API.
Looking forward to hearing from you
