Microsoft Visio 2010 models can be saved to the VSD format, is it possible to import these files into erwin using the MetaIntegration Model Bridge (MIMB)? This is accessible through erwin 'File' menu under 'Import' and 'From External Format...'.
The MIMB cannot import a VSD file as it only supports erwin XML and ERX formatted files from Microsoft Visio. Saving to either of these formats needs to be done within Visio itself. The ability to save to these formats is made by an add-on to Microsoft Visio and you need to contact Microsoft in regards to getting this add-on.
