30075 - Drawing and CAD for the Design

Learning outcomes

Knowledge of the main software tools for technical drawing and their employment for the design of rural buildings. Expected skills: CAD representation of farm buildings and relative technical features. These skills are increasingly required in the professional activity and are necessary for the agronomist qualifying examination.

Course contents

Prerequisites: The student who accesses this course has a good preparation in the fundamentals of mathematics and physics. Such knowledge and skills are provided by the basic teachings delivered during the first year of the degree course.

 

Teaching unit 1. Rural buildings outline (10 hours) 

Expected results: the student knows the main criteria for sizing and designing basic rural buildings.

·       Farmstead layout

·       Construction characters and design criteria of the main typologies of rural buildings:

• barns, warehouses and tool sheds

• cattlesheds

• or free-stall barns

Teaching unit 2. Fundamentals of technical drawing (8 hours)

Expected Results: The student knows the conventions for the preparation of technical drawings for the representation of projects, the student knows and is able to apply the rules of projective geometry with regard to the orthogonal projections and sections of buildings.

• Drawing tools and conventions in the representation

• ISO (UNI) formats

• types and thicknesses of line

• dimensions and scales of proportion

• text and symbols

• Fundamental geometric constructions

• Orthogonal projections

• plans and plants

• front views

• sections

Teaching unit 3 Building design process (4 hours) 

Expected results: the student knows the structure of the design process and is able to recognize which level of detail is needed in several possible cases of application; the student knows the content of the drawings relevant to the different phases, and the main tasks of the designer and other professionals involved.

 

• The design phases: preliminary, final, executive

• The organization and content of project documents

• Roles and responsibilities of technical professionals involved

Teaching unit 4. Computer Aided Design (CAD) (18 hours)

Expected results: the student knows the operation of a CAD software and is able to use it for the preparation of drawings  for the design of basic rural buildings, up to the scale of detail of the final design.

Lecture notes

Teaching methods

The course includes the carrying out of activities of lectures and guided exercises of drawing and design through CAD.

With regard to the didactic activity, through the administration of the teaching units in the classroom, students acquire the knowledge necessary for understanding the design criteria of simple rural construction works and the theory of technic representation. The acquisition of knowledge and understanding are constantly monitored during the course of the lectures, through a continuous interaction between teacher and students. This interaction is expressed in the discussion about the strengths and difficulties of various design solutions considered and the critical analysis of case-study drawings.

As for the guided exercises in the CAD laboratory, the teaching unit 4 " Computer Aided Design (CAD) " is taught entirely in the laboratory of CAD by conducting guided exercises that students develop in first person with the supervision of teachers. The faculty-student interaction in this part is constant and takes the form of periodic reviews in which the students are stimulated to become critical thinkers, guiding them towards processing and graphic design solutions best suited to develop the theme.

Assessment methods

The exam for this course will be conducted at the presence of the teacher of each module in the following ways. The final exam consists of an oral test through which the knowledge concerning the whole course is assessed. During the oral exam, the student is required to submit the drawings produced within the tutorials. The exercises consist in developing CAD reproductions of a rural building (which requires at least plan, elevation and section) and in the project from scratch of a rural building (which requires a minimum plan of the farmstead, plant, two elevation views, one section and the technical report).

The discussion of the first work of exercise is aimed at verifying the learning of the fundamentals of technical drawing and CAD tools. The discussion of the second work of exercise aims to evaluate the preparation on the criteria for the design of rural buildings and the ways of representation and presentation of the design.

Teaching tools

Overhead projector and PC, computer laboratory with CAD software.
