점선면 : Point, Line, Plane : 공간지

Hello. This is the dotted line development team.

We have launched an app that can solve the spatial perception problem of the job aptitude test of large companies.
The currently supported problem types are the unfolded type, origami type, the punching type, and the stacking type.
Each type is divided into easy, medium, and hard.

Incorrect answer notes are also provided, so solve the problems and improve your spatial perception!

thank you.
