I am looking to download a newer version of drawing flattener but am not able to find it.
Could you please provide me following details, so that I can guide you in proper direction.
1. What is the current version of AutoPLANT you are working on?
2. What is the Latest version of AutoCAD you are using?
If you have AutoCAD 2016 AutoPLANT flattener will not be available as separate installable, it will come in bundle with AutoPLANT Modeler SS8
You can download AutoPLANT Modeler from following Bentley fulfilment Center link:
Hope this help. Looking forward to your reply.
