@stefbeno, no, I practice exactly the same way, I create an assembly, I do the symmetry of the part using as a sym plane a plane of my part in not of the assembly I save the part to keep the new configuration then I close the assembly without saving it., In addition, there is an advantage if you need a part plan, you just have to recover the original plan, point to the symmetrical part and change the configuration.
Otherwise I do it in the room itself. I create my piece and then I create a symmetrical gonfig and in this configue I choose a side of my piece and create the sym without merging the bodies and remove material from my masterpiece and there I have my two versions.
@manu67 yes it works too, but by doing it like this you can't get the plan of the original part to create the symmetrical plan. This is the big advantage of the above method.
Small clarification it sometimes happens to me to make a bogus assembly to make the symmetrical part with derived config then delete the assembly in which I created the config and no worries the symmetrical part updates well
I did the same thing and I'm just tinkering a little bit in the configs to have them separately. Because the sym is in the default, I put myself in the sym config and I create a new sym and delete the one in the default as they are well separated.
Hello, Thank you PL for the links to the tutorials. Not only is it very clear but very simple to follow. I think Claow and anyone else who is experiencing the same problem will have to follow the tutorial.
