I'm writing a VBA Macro to automate some tasks on various Drawing Sheets, and am running into some issues in actually selecting a Sheet.

I tried recording a macro where I shifted between Sheet1, Sheet2, and Sheet3, but the coding didn't seem to reflect anything: 
 

Dim swApp As Object

Dim Part As Object
Dim boolstatus As Boolean
Dim longstatus As Long, longwarnings As Long

Sub main()

Set swApp = Application.SldWork
