I was a bit confused with obj files.
I thought they contained some compiled java code but they are 3D wavefront files.
The thread you pointed made a lot clearer
Thanks

Hello,

I'd like to create some new furnitures like an electric outlet and a light switch as drawn in electric schemes.
However I can't find any source code example of a furniture where I could start from.
I did find an example of a (volume)plugin on the website but I'm afraid that's something ...
