What DB Roles should I have to use SQL with HyDraw CAD and how do I change these roles?

Within the SQL Database, users should have the dbcreator role assigned to their login credentials in order to read and write from the database.
To change a user's role within the SQL database do the following steps:

1.     Open SQL Server Management Studio. Select the username from Logins and right-click select Properties.

                        
               2. Login Properties dialog pops up. Select the Server Roles and select “dbcreator” (public is by default selected and can’t be selected).
