Well, a 3D model or shape means a 3D (looks real) house or tree or even a cube or a sphere. Paper is flat, so things on it are two dimensional (2D). If you change the appearance of a square into a cube by adding extra lines, or a circle into a sphere by clever shading, you're making it look three dimensional (3D). Two dimensional figures have width and length; 3D figures also have height or depth.
Paper is a 3D object.
A heptagon is not a 3D shape. It is a seven sided shape. It could be designed on 3D software if necessary.
A shape in 3D is a polygon. Poly=many and gon=shape.
Many 3d shapes have a corner.
A 3d shape can have infinite sides
