I am looking for...
 

a kind of online database where you can find drawing of an aircraft (optimal would be three views: 1) front 2) above 3)left or right side.

Would this be available by OEM?

I checked janes but unfortunately its not an online rescource....

Thanks a lot

Would something like that suit you?

I think I found what you're looking for, they are at a cost though.

Google's your friend, he says to have more than 200 types.

Database
 

If you are looking to re-produce the pictures this might not be too good, but otherwise is excelent.

Aircraft Performance Database V2.0

You can also find more data here;

SKYbrary - Category:Aircraft Types

These sites are also very good for helping young Miles learn his types, only trouble is that now he is better than me!
