How it works?
Now let's see how the game process looks like. Let's build a simple mill, for example. After pressing "Start assembly", the camera immediately takes us to the shelf with parts relaxing on it, as if it was a sunny beach. We choose the largest one and pull it aside using wasd buttons.
We'll need an "autonomous" electric motor, so we choose it and bring it to our first part. We arrange it in a way, so that the holes for fasteners are opposite to each other. After a competent click on space button, our parts are pulled up and we see inseparable bolts and nuts. I select both bolts and press space button again. The motor is pleased with its attachment joining and is ready to rotate something on its shaft. Wheel? No problem! We expand it with ctrl q, bring it to the motor shaft end, press the spacebar, and select the nut.
