+
+For complex machines, there is not any long chain of crafting. In reality when you want to build a complex machine, you actually have a overall plan and you just have to follow it to assemble essentials components right ?
+So it's the same here with machines. You have to get an overall plan of a mechanism and just put it in the craft table with required components ... and it's finished !
+Yet the problem is to get the overall plan. There is currently only one way to get it: have it generated by a computer: my computer mod. Idealy, this mod would require a sketching table node to achieve plans.
+
+* enter the following command in a computer : 
+	design ELEVATOR 
+(replace 'ELEVATOR' by the plan name of the machine you want) then the plan is added in your inventory.
+put it randomly in the crafting table with components Image
+then you have the machine crafted.
