65938 - Drawing And Cad For Green Design

Learning outcomes

At the end of the course the student acquires knowledge and mastery of drawing techniques based on descriptive geometry, and of basic principles of CAD. At the end of the course the student has the operational ability to draw on a scale natural and anthropic elements of landscape. The ability to use CAD tools turns out to be increasingly supportive in the training process and in the professional career, and it is a prerequisite for the practice test of the qualifying examination for the profession of agronomist.

Course contents

This course is part of the integrated course "DRAWING AND SURVEY WITH CAD AND GIS," along with the course "Geomatics and Surveying for Green". Both courses, which are part of the integrated course, focus on the digital representation of land and green spaces, complementing each other in terms of tools, approaches, and objectives. Specifically, the course "Drawing and CAD for Green Design" (1st semester) focuses on the large-scale graphic representation of green spaces, both manually and using CAD, for the correct visualization, management, and creation of graphic design documents for green spaces. The course "Geomatics and Surveying for Green" (2nd semester) focuses on instrumental surveying, representation at various scales, and analysis of land and green spaces using topographic and GIS tools. This course integrates graphic representation with various types of information to create georeferenced databases to support the design, management, and planning of green spaces.

- Texts and symbolism.

Teaching Unit 2. Projective Geometry
Expected results: the student knows the main forms of representations that can be used in technical drawing and is able to use them for the representation of open spaces.
Contents:
- Orthogonal projections
a) plans and plants;
b) fronts;
c) sections;

Teaching Unit 3. Architectural survey
Expected results: the student knows the operating procedures for conducting architectural surveys of open space and is able to put them into practice in case study exercises.
Contents:
- Fundamentals of architectural survey: theory and preliminary analysis of the site
- Operating modes: tools and procedures
- Field applications.

Teaching Unit 4. The computer-aided design
Expected Results: The student is able to use the CAD for the execution of the drawings related to the technic representation of open spaces.
Contents:
- The basic commands of a CAD
- CAD representation and layer styles
- Printing settings
- Laboratory exercises representation of an green area.

Teaching methods

The basic concepts of technical drawing and projective geometry are going to be explained, highlighting the potential applications in the field of representation of green spaces and landscaping.
Through the study of important technical and field activities (teaching unit 3), the connection between the theories exposed, and application requirements in the field of the design of green areas and landscaping is stressed. In fact the course includes also a part of training in the field, conducted with the support and guidance of the teacher, where students put into practice the knowledge about the survey of open space taught in classroom, through measuring instruments made available by the University.
Illustrating the main characteristics of CAD software, students are given the opportunity to understand how to use, including by computer, drawing techniques learned. In particular, the teaching unit 4 'computer aided design' is carried out as a workshop activity in a computer room equipped with CAD software. The teaching method involves the carrying out of short lectures on the characteristics and operation of the software accompanied by exercises held by students with the support and guidance of the teacher. This workshop activity leads students to set and structure the main phases of exercise work required for the exam.

As concerns the teaching methods of this course unit, all students must attend Module 1, 2 [https://www.unibo.it/en/services-and-opportunities/health-and-assistance/health-and-safety/online-course-on-health-and-safety-in-study-and-internship-areas] on Health and Safety online.

Assessment methods

The course is part of the integrated course Drawing and Survey with CAD and GIS (I.C.), together with Geomatics and Survey for Green; therefore, the evaluation of the course takes into account jointly the level of knowledge and skills acquired by the student in relation to the contents of the two classes.
The knowledge and skills taught in this course are evaluated in the following way. The exam is carried out through oral questions concerning knowledge inherent to the entire course. The test includes the presentation of graphic products regarding the exercise, and the formulation of theory questions on different aspects of the program.
The execution of graphic tables relating to the relief of a green area is required, normally to be carried out in groups of 3-5 students and presented in the examination. We are requesting the following documents:
- Explanatory report of the surveyed area and the survey procedure, including sketches and photos;
- Top view (optionally with shadows) in CAD;
- Plant in CAD.
The graphic tables must be produced in a suitable scale and presented in tables of suitable formats ISO (UNI).

Students who can not attend classes have to contact the teacher to agree on how to proceed with these graphic tables.

Answers to questions are evaluated based on their accuracy and thoroughness with respect to the topics covered in the course, the ability to present the topics using technically correct language, and the student's demonstrated analytical skills, according to the following scale:

• Preparation on a very limited number of topics covered in the course and analytical skills that emerge only with the instructor's assistance, using generally correct language → 18-19;
• Preparation on a limited number of topics covered in the course and independent analytical skills only on purely executive questions, using correct language → 20-24;
• Preparation on a large number of topics covered in the course, ability to make independent critical analysis choices, mastery of specific terminology → 25-29;
• Substantially exhaustive preparation on the topics covered in the course, ability to make independent choices of critical analysis and connection, full mastery of specific terminology and ability to argue and self-reflect → 30-30L.
