How can I switch between Logical and Physical models in erwin DM 2020 R1 - there is no visible op (4310719)

Problem: 

How can I switch between Logical and Physical models in erwin Data Modeler 2020 R1. I don't see this switch in this version of the program, but in the old one, it was there.

Solution:

Please locate the toolbox toolbar (figure 1) and click the down arrow.  You will then see the Logical/Physical model selector (figure 2).

 It is also there by default, but may be hidden if the application is reduced in size, in which case making it wider should also make it visible.
