I am using Solidworks 2017 Academic with HSM Ultimate 2019. Whenever I open Solidworks and start a new part, the HSM tab in the Command Manager is always shown. My preference is for the Sketch tab to be the default tab.
Searching the forum I know that the Command Manager has a 'memory' so I close the Command Manager with the Sketch tab active. Reopening the Command Manager the Sketch tab is shown by default. Now if I close the part without exiting Solidworks and start a new Part the Sketch tab is shown by default. However when I close Solidworks, reopen it, and then start a new part the HSM tab is back showing by default.
I have also tried saving part templates to no avail.
