how models came?

[NycRayJai]

i always wondered how the kit models we build today became what they are.

like for people at bandai

for models in production, do they used some auto cad like program to design the models? then have this machine like car manufactors have which produces a plastic copy?

i don't think someone sits there all day sculputing it?

when when it's all finalized they start mass producing them the in factories?

thanks
