It may happen, that opening a part will directly lead to a "sub-environment",
such as "Sketch", "XpresRoute", "Framing".etc. without the possibility to go
back into the "normal" operational mode. How to get out of this?
Solution 1. Open the part.
2. Go to View -> Window -> New Window.
This will open an additional window of the same part, but in its "normal"
3. Now change and close the previous window.
