Hello @Rim-b
Excellent!! But not perfect... This is exactly the expected end result, except for the placement.
I insert a sheet metal part into the host sheet metal part, but I can't position it as desired. Is it possible to rotate the inserted sheet metal or are we limited to translation during insertion only?
The initial idea of going through an assembly was mainly to make the positioning simple, before it all ended up in a loan.
Hello
No, there are assembly functions (move with constraints).
But quite frankly, it's a gas factory, seen from my window, what you're trying to do.
You have to choose the right mode at startup (assembly or part within part) because "converting" afterwards is hours and hours of work. I'm not even sure that a macro can do it without generating positioning errors or at least will have to spend hours on this type of development.
I often use the insert part function and I confirm your dir cyril, the thing jumps at the slightest change in the tree sw doesn't like to play too much with the recovery bar,
For the copy of a function with macro I don't think either, I don't see how you can modify a hole or a removal of blind material or through everything without affecting the other bodies!
Hello
Inserting a part within a part works. On the other hand, if you have more than a dozen parts, it can very quickly be a hassle to manage. If you want it to work, the best thing to do is to probably not use constraints when inserting parts, but only positions.
A possible solution would perhaps be to make groupings of pieces that go together (so make sub-pieces) and then to insert a dozen pieces in a room.
NB: In terms of reconstruction, it may be difficult to manage in any case.
Yes, I confirm and it's quite penalizing when a customer sends you an ASM in STEP format for example or other neutral format to make you do an RDM simulation. Not to mention that you lose all the constraints in the process.
Good luck 
Hello.
Thank you all for your very informative answers!
So, I tested the insertion of a part in a part, the file weighs 2 times less than an assembly with the same part made virtual.
The fact that the weight goes from double to single is not negligible.
However, reading this topic, I have the impression that virtualizing the parts in an assembly remains by far the simplest, most practical and flexible solution.
What a shame that the file weighs twice as much...
The pee trick is indeed an interesting possibility, @froussel
Checking in lapi, it seems to me that it's playable:
Browse the components one by one
Retrieve the position and orientation of the component relative to the assembly origin.
Insert the component into a part and break the link.
Detecting new bodies (a bit of a headache!) .
Apply orientation and displacement to these new bodies
By breaking the link, the functions of the inserted part are recovered in the tree, the miracle is that SW only applies them to new bodies (it modifies the definition and action areas of all bodies to an automatic😀 selection) which avoids the problem I mentioned earlier, so the link is broken the tree and stable,
The only bimol I find is that these bodies are positioned in relation to the part origin not by stress interactions.
Not to say that the tree structure will be very very long depending on the number of components and their complexities
If attached a description of the points

Hello @Lynkoa15
THANK YOU! This macro looks great. I test it as soon as possible.
Just one thing. On one of my macros in the process of dev' I needed to apply view rotations, and in order to have the most accurate PI value possible, I wrote this:
Dim DtR# '(DegToRad)
DtR = (4 * Atn(1)) / 180 ' "Constante" de conversion degrés en radians (Pi/180)
This code gets PI and divides it by 180 to change the degrees to radians.
(For example, (3 * DtR) converts 3 degrees to radians)
In short, to have a "perfect" PI in VBA you need this code:
Dim PI# '(THE_number)
PI = (4 * Atn(1)) ' "Constante" Pi calculée
When I say "perfect" it's obviously within the decimal limit of the Double (#) type.
Of course, there is an advantage to using a constant, as long as you remember the first 14/15 decimal places of pi (3.14159265358979)
