In Mechanical, you can open and close the Scripting view from the ribbon's Automation tab. In the Mechanical group, clicking Scripting switches between opening and closing the view.
For information on using the Mechanical Scripting view, see Scripting Introduction in the Scripting in Mechanical Guide.
Note: You can revert to the ACT Console by changing the scripting view preference under File > Options > Mechanical > UI Options > New Scripting UI. Mechanical must be restarted to see the scripting view change.
