Does the 6i version support converting diagrams (FHD, ER, etc) into other formats yet, such as a bitmap or BPwin/ERwin?
You can select the objects, copy and paste onto a Microsoft Word document with Designer 6i.

Data Modelled from Designer can be reverse engineered. If BPwin/ERwin can accept/convert reverse engineered as an input into a diagram then there should be no problem.
