# Pieces of Drafting [3] (Solución) [Normalization] [Education]

Solution to the third piece of technical drawing.

They have represented the two main views (elevation and profile) leaving the student carrying a plant that completes the third projection (not necessary for the representation of the object).

# Pieces of Drafting [2] (Solución) [Normalization] [Education]

Solution to the second piece of technical drawing.

They have represented the two main views (elevation and plan) leaving the student performing a profile that finished defining one of the inclined planes.

Between the two possible profiles, we use one hidden lines of least.

# Test geometry and technical drawing

One way to measure our level of training in a particular subject is to conduct a self-assessment test.

In the case of the teaching of geometry or technical drawing no generalized models for this task.

This page shows a Java applet that can be used to measure our level of graphic expression in subjects (Drawing) baccalaureate level or first-year engineering schools.

# Educate playing with impossible figures

Impossible figures can be real simple objects that produce optical illusions obtained by proper perspective.

Use from the educational point of view can be justified in requiring a detailed analysis for understanding.

They can also be approached as a challenge for the student who can compete with others in an educational game object identification. Do not forget that play activities encourage interest in the learning process, entertain and arouse curiosity for the study of new cases: Learning enjoying.

# Introduction to technical drawing : Normalization

The engineering drawing to represent three-dimensional objects on a two-dimensional format (papel) using projection techniques that are studied in the systems of representation, particularly Diédrico System. Using a projection system rollbond (the center of projection is located at infinity) provides interesting advantages from the point… (leer más)
