It's display the length, width and height
A 3D wall can include all interior framing, drywall, baseboards
Different between 2D and 3D Object
From the 2D drawings, you have to imagine how the object look like
With the 3D drawing, you can see the actual object in all directions
You can generate 2D drawings from the 3D object
You can render the object to create photorealistic image of the finish model
3D Model Types
Wireframe Model
Only edges
No surfaces between the edges
Let you see through the model
Surface Medel
Consist of infinitely thin surfaces that represent the shell of the model
Create complex geometry, like car body, cell phone
Mesh Model
Consist of polygons that form edges, faces and vertices
No mass
Can create complex shapes that can be creased, split, deformed
Can be shaded and rendered without a mass
An alternative for solid
Solid Model
A volume that represent a 3D object
Mass inside, center of gravity, moments of inertia
The only model can be used for mechanical and thermal analysis
