Physical / Logical Model?

Hi,

I have used ERwin before but not VISIO, am using this product for the first
time.

I have done reverse enggineering from one of existing data bases in SQL2k5
in to Visio professional 2007 drawing. I have 2 questions now..

1) I am seeing only physical model in visio, where can i see logical model
of the schema, This option was available in ERwin?

2) How can i build a new sql2k5 database by extracting the schema from the
visio that i created.

Can any one please help me out as am newbee to this product.

--Regards
