Now i will talk about what wireframe which is a way to view the lines of the Primatives as shown by the image below.Now I am going to talk about how I extruded a 2D surface to a 3D surface this is done by making a primative on the grid as shown by the images to the left you have to drag it to make the 2D object then you have to drag it up to extruded it also show by the image to the left.
The way to edit and extruded an 3D object on the grid is by using varied tools but with all the tools used to edit the shape you use the Vertices which are point on the grid with the X,Y,Z points on it as shown by the image to the left. They are used to extruded a shape which is when you get a 2D object and drag it up to make it a 3D object.
With a Primative there is polygons that makes it up with different elements called know as Faces for example there are five face on a cube and on each primative there are lines which can be curved you do this by selecting a polygon and using the Select and Move tool to edit the shape and make it more curved. A group of polygons connected to each other by Sharded vertices is know as an elements.
One of the most popular methods of constructing meshes is box's modelling which uses two simple tools which are the subdivide tool splits faces and edges into smaller pieces by adding new vertices. For example, a square would be subdivided by adding one vertex in the center and one on each edge, creating four smaller squares and the second tolls used is the extrude tool is applied to a face or a group of faces. It creates a new face of the same size and shape which is connected to each of the existing edges by a face. Thus, performing the extrude operation on a square face would create a cube connected to the surface at the location of the face.
