Prerequisites: none
Target skills and knowledge: Any architectural or engineering building, from conception to design phase, finds its configuration not in reality, but rather in a mediation that prefigures it and establishes spatial, metric and functional values ​​- along with a whole series of factors like social, cultural, theoretical and historical issues - which must be represented before construction.
this course proposes to provide the Civil Engineering students with the fundamental knowledge, both conceptual and practical, inherent to drawing for design and communication, as correct and objective as possible, of the building project.
Examination methods: To pass the exam students must take 3 written tests
and make drawings by hand and using digital programs.
Assessment criteria: 7 points to each written test
4 points to hand drawings
5 points to digital drawings

1. Introduction to representation and geometrical methods of representation.

2. Elements of elementary geometry (definition of point, line, plane and space; definition of coplanar, incident, parallel, coincident, skew lines; definition of projection from a center of a point on a plane, of projection of a point on a plane according to an assigned direction, orthogonal projection of a point on a plane; definition the rotation of a plane; definition of a symmetrical figure with respect to a point, with respect to an axis).

3. Basics of projective geometry (definition of projection from a center and section with a plane; notion of projective space: extension of the Euclidean space to infinity,
definition of line and plane at infinity: parallel lines, parallel planes, beam of straight lines with a center P at infinity, star of straight lines with center P, beam of planes with axis p)

4. Orthogonal projections (Method of Monge): reference system in space and in the plane; representation of the point, of the line and of the plane and particular cases; belonging condition of point to line, line to plane, point to plane), parallelism and coplanarity conditions. The plane for the third projection. Intersections between planes, between straight lines, between line e plane. Rotation of projecting plane.

5. Orthogonal projections (Method of Monge): The section with projecting planes of simple solids (section of the parallelepiped, section of the pyramid, of the cone, section of the sphere) and complex solids.

6. Axonometry (parallel projections): introduction to axonometry; orthogonal and oblique axonometries: reference system in space and plane.

7. Axonometry (parallel projections): isometric orthogonal axonometry; the
monometric and dimetric oblique axonometry: cavalry, military and
planometric axonometries.


1. Paper dimensions, folding paper and title blocks; scale reports; dimensions (measurement lines and reference system, dimensioning systems, conventions and dimension symbols); line types;
hatches (conventions of sections and hatches for the representation of the materials).


1. Building materials (stone materials, bricks, concrete).

2. The structures (foundation structures, the vertical masonry structures, the structures vertical and horizontal in concrete, the steel structures, the floors, the ceilings, stairwells and elevator).


1. Plans and cadastral maps.

2. The plans (foundation plans, static scheme, distribution scheme, technological plans)

3. The vertical sections.

4. The elevations.

5. Construction details.


1. Metrology.

2. The survey methods (direct survey method).
Planned learning activities and teaching methods: OBJECTIVES

The course deals with general topics on technical drawing. It is set to teach the students the main two methods of representation, useful for any kind of engineering subjects: orthogonal projections and axonometric views. It focuses on technical drawings, providing theoretical and practical skills for the analysis and the representation of pure geometric objects.
The course provides also the base of digital skills for 2D and 3D representation.


The students will be able to manage the basic rules of projective geometry and descriptive geometry for representing pure solids in the Euclidean space. At the end of the course the students will be able to face:

1) the geometric problems of the space with orthogonal and axonometric projections (section/intersections/revolutionary solids/noteworthy surfaces).

2) the appropriate digital commands to set a print of a 2D drawing and to produce a 3D virtual model.
Additional notes about suggested reading: for hand drawing:
A3 paper, rulers, 4H and 2H pencils, white eraser, compass

for digital drawing:
Autocad, 3D Studio Max
