How i get the archive simgeom of a sims 3 hair??

I do not know if it is possible to use s3pe without the game installed, but there are other software that can extract .obj from any file. Unfortunately, i cannot find the one that I used (something related to tomb rider??), but if you were to google, you'll see other software

here is a tutorial
