Net nets are the original form of building space that has been cleaved. Or another understanding of nets is a flat building which when linked will form a building space.

UNDERSTANDING BEAM NETWORK

From the definition of beams and nets above, it can be concluded that the nets of the beam are the result of a unit of wake which is a cleavage from a building in the form of a beam.

Characteristics of Beams

- Has 12 ribs
- 8 vertices
- Consisting of 6 sides
- The entire angle must be right-angled;
- Has 12 diagonal fields and 4 diagonals in the form of building space

### Properties of Beams and Beams

Following are the general characteristics of the beam :

- Beams are composed of 3 pairs of the same side (a total of 6 sides).
- Each side is rectangular, square or rectangular.
- At least it must have 1 pair of sides with different shapes.
- Has 12 ribs.
- The parallel ribs are the same size.
- Has 4 diagonal fields.
- Diagonal parallel planes have the same size.
- Has 4 diagonal spaces and all have the same size.
- Each diagonal field is rectangular.

#### How to make beam nets

To further strengthen the understanding of beam nets, we will try to practice making meshes.

- Take a box in the shape of a beam
- Cut the cardboard according to the pattern of the cube at certain points. Do not leave one side down and one side.
- Then you will get the form in the form of beam nets like the picture above.
- After we divide the cardboard box into a network of beams, we can see that the mesh networks are composed of 6 rectangles consisting of 3 rectangles that are equally large. Then

ABCD rectangle is the same as EFGH.

EHDA rectangles are the same as BCGF.

ABFE rectangle is the same as DCGH.
