how do you use blueprints?

[*Yuki*]

and, most important question - how to remove blueprint item from inventory?

To remove: Right click, press the trash button.
Blueprints are used to map out a plan for a factory. To make one, click the blueprint button, then click and drag once you have chosen to make one. To place a blueprint, select blueprint and click where you want it to be. This gives you the outline for where you want your items, and robots can help build it for you as well. This is just a brief explanation, as blueprints and deconstruction planners can be used for many things.

I think you are currently unable to delete "blank" blueprints by right clicking them. There simply won't be a trash icon. To fix this, use the blank blueprint to blueprint anything at all, then delete it.

Blueprints are there mostly to automate the placement of objects. My main use for them is to lay down rail line blueprints, that help me maintain a consistent design for my rail network. Blueprints are almost entirely worthless without construction robots to lay down the objects for you, but I suppose you can use the ghosts laid down by it to plan out a base ahead of time.

For me, this is the most frustrating part of the game. Hopefully this is changed on release.
