Can someone teach me to make seats that you can sit in as if they were vehicles, cos i want to make a meeting room type thing for a clan.

Vehicle positions are partly odf and partly model. You'd need to find or make your own meeting table model before you can set up the odf.

you could use the space turret control seats

I have found a table with 4 seats around some time ago.

Could that be useful!?
I could reupload it for you because i really don't know where i found that.

i think challenger released it, but thats not the point of the topic i suppose
