2nd topic
Simple shapes,
their projections and parameters
Embedded Files
The purpose of an engineering drawing is to clearly and accurately capture all geometric features of a product or component so that a manufacturer or engineer can produce the required item. We can divide all things into smaller parts, which you can create with any CAD system and use for modelling tasks.
In this second topic you will learn how the projections of simple shapes are obtained and how these projections are used in CAD/BIM. Exercises and a test will help you master the material.
CONTENT
2.1. About the simplest shapes ~15 min

Expected outputs
Expected outputs
In this topic, you will accomplish the following:
develop an understanding of the form of a shape,
learn how to choose a base view,
understand the use of the first/third angle system and how to choose a system for arranging images/projections of an object in a drawing, and
learn how to use shape dimensions to derive the projections required.
Expected outcomes
Expected outcomes
The student will understand the relationships among spatial structures.
The student will be able to create a visualization of simple objects (as a 3D-model).
The student will develop his or her visual literacry and have a better command of the vocabulary necessary to express his or her ideas.
The student will be able to imagine how a 3D model can be assembled from 2D parts, as a digital scale prototype, to convey his or her ideas.
