assembly instructions and spare part book?

I think I saw some introducing video about some Add-in (or similar) about SW which is good to make assembly instructions and maybe a spare part book. I need to make assembly instructions for our production and the spare part books for our customers. Are there any good add-ins? Or is the best way to do this just to use normal SW drawings? I am looking to make some sort of book like you got with IKEA furnitures. I think the regular drawings are bit too clumsy for this purpose. Now I have used the normal drawings and exploded view for this.
