You are welcome.

You might take a look here for some explanation of the differences...

Part and PartDesign

There's a cross in the top right.

The details to which you refer are for Part Loft not PartDesign Loft, which can be found here

in particular I refer you to the notes.

Not experience just look in the correct place.

I'm not really sure what you are asking.

Part Design has a single solid rule, if you want to combine two objects in made separately in part design, then it sounds like the workflow is faulty.

This is not other CAD, if you prefer that then use it, otherwise learn how to use FC.

In the loft sketches you must make them in the same order inside rectangle then outside rectangle in both sketches.

If you look carefully at the loft you can see it crosses over in the middle.

If a sketch has attachment (as they usually do,) it is attached to a support.

Don't you know where the properties are?

Which exercises?

It is possible to change the support Property.
