Hello,
I wanted to create a simple Battery DC PSU. There I want to have +3,+6,+7.5 and +12.
In this PSU should be
-2x(2xAA battery holder)
-1x(Single AA battery)
-1x(9V battery)
Then I just started inserting everything in LTSpice

There it is. The only problem is that I need the 12V ground and the 3-7.5V ground. But LTSpice wont let me use both. It doesn´t make a difference if I connect for ex. a LED to the 3-7.5V ground but it seems like it is grounded to 12V or in the opposite way :/
Now I want to ask you, is this even possible in LTSPice? Or should I remain on one voltage supply for each schematic, but how should I use 2 or more different projects together if there can only be one ground?
I´m sorry for my bad language
