The declaration for swCustProp is missing, by adding the 3 lines above it works (be careful your code still needs a good cleanup (2x Set swModel...)
Here is the code to clean up:
Dim swModelDocExt As ModelDocExtension
Set swModelDocExt = swModel.Extension
Set swCustProp = swModelDocExt.CustomPropertyManager(tConfig(i))
bRet = swCustProp.Get6("POIDS", False, sValout, sMasse, False, False)
I answer myself, missing the set of the swCustProp variable hence the error:
Set swCustProp = swModelDocExt.CustomPropertyManager("POIDS") 'Propriété à changer si ce n'est pas celle-ci
Yes, I confirm that there is some cleaning to be done.
It's DIY, I'm trying to understand all this, not easy 
I cleaned up and I have a new alert about Dim i:
(tConfig(i)) is it good for All Configs?
Hello
Dim i must be declared elsewhere in the code.
It would take the complete code to understand.
So, the problem is the over-positioning of the DIM i as integer declaration.
Basically, since there is the line Set swCustProp = swModelDocExt.CustomPropertyManager(tConfig(i)) at the beginning of the macro, vba initiates the variable i on its own.
It therefore considers that there is a duplicate variable declaration.
For my part, I prefer to have the variable declarations in global for all Subs rather than declaring them in each procedure (depends greatly on the use of variables and the different procedures/functions in the macro)
You also have the swApp declaration 2 times, once above the Sub and once at the very beginning of the Sub.
Before making a declaration, you must find out if it is not already existing.
And in the idea, making the declarations at the very beginning of the sub or outside (before the sub) is cleaner in my opinion.
Something like this sounds better to me:

Thank you very much
I answer myself. I searched and searched... 
When I first launched my macro, it stuck at this line:
I did END the command and in the F8 properties, I could see that PROFILES/mass/WEIGHT and MATERIALS were well informed. It was therefore missing SURFACE PIECE
I restarted and the macro worked until the end by filling SURFACE PIECE well.
As if the first time the macro was launched, it was unable to retrieve the value of WEIGHT which is calculated just before.
So I added a part reconstruction between MATERIALS and mass property recovery and it works. 
I tested my macro with a single configuration creation and the SURFACE PIECE was correct.
Then I tested my macro by integrating the creation of 3 configurations: 00 / PC / R1018.
SURFACE PIECE is created well in the 3 configurations, but I only get a good calculation result on one configuration.
Do you have an idea of the problem?

I answer myself again!
I modified the macro by creating only config 00 at the beginning, then filling in all the properties.
Finally, I create all the other configurations, which take up the properties of the initial configuration.
YIPPEE!!!
Thank you for the help. I managed to get by with your advice.
