Bentley Map Schema register update a Bentley Map project schema with an ESRI shapefile feature schema and/or an ESRI personal geodatabase feature schema.
To load this tool you will need Microsoft .NET 3.5, but if you have MicroStation V8i installed on your machine, then you already have it.
Also, if your shapefiles are stored in long path names or with long file names, then you may need Visual Fox Pro 9.0 OleDB driver to be installed on your computer. This driver is packed in the SchemaRegister.zip file.
Now, with very special thanks to Kees Van Prooijen, with application manual.
