Sheet Preparation By Ordering And Swapping Cells Vba Macro

in 1 workbook i have 2 sheets (sheet1 and sheet2) with same format of data that I need to compare and compile in sheet3 by a primary key column.

example:

sheet 1 & 2 data format:

|Atr1|Key|Atr2|SubAtr1_1|SubKey1|SubAtr1_2|SubAtr2_1|SubKey2|SubAtr2_2|Atr3|
..................... ......................................../......................................../
......................................Set1.....................................Set2

To be more specific I can compare this with an electrical wiring table, where:

Key is the wire number
Atr1, Atr2, Atr3 are general atributes of the wire number
Set1 are the atributes of the first end of the wire, called "from":
SubKey1 is the "from" device and its subatributes SubAtr1_1 & SubAtr1_2
Similar for the other end of the wire is Set2.
This means that Set1 and Set 2 have similar format & type of data.

I have found on your site an example of macro that is doing the comparision between the 2 sheets of data but I encountered a problem...sometimes on sheet2 Set1 and Set2 are reversed and are highlighted as a difference but I don't want this.
Please help me with macro that would create a rearranged copy of sheet 2 respecting the following conditions:

1. if Key from sheet1 cannot be found on sheet2 then copy entire row on sheet3.
2. if Key from sheet2 cannot be found on sheet1 then copy entire row on sheet3.
3. If Key from sheet1 = Key from sheet2
If SubKey1 from sheet1 = SubKey2 from sheet2
& SubKey2 from sheet1 = SubKey1 from sheet2
Then reverse Set1 with Set2 by swapping cells
and copy entire row (with Set1 and Set2 reversed)to sheet3.

All data on sheet 3 should be sorted by Key.
