Technical drawing

The course aims to provide students with adequate theoretical knowledge and practical skills in drawing methods, considered as a fundamental language for the representation and communication of design

1. THE SCIENCE OF REPRESENTATION

The biuniqueness between reality and representation. Projections: central and parallel projections.

2. ORTHOGONAL PROJECTIONS

Monge's method. Projections of points, lines, and planes: their traces and projections. Auxiliary planes and representations on them. Conditions of belonging. Intersecting and skew lines. Rotation. Representation of objects. Sections.

3. AXONOMETRIC PROJECTIONS

Three-dimensional representation: orthogonal axonometry, oblique axonometry. Axonometric exploded views.

4. QUOTED PROJECTIONS

Representation of fundamental entities: plane, line, point. Rotation for determining the terrain profile. Representation with contour lines. Intervisibility.

5. SURFACES

Primitive surfaces (cone, cylinder, sphere): definitions. Projections. Sections. Axonometry. Perspective.

6. REPRESENTATION OF EXISTING OBJECTS AND PROJECTS

UNI Standards (Sheet formats, Sections, Dimensioning). Representation scales. Graphical error at different scales.

7. SURVEY OF EXISTING OBJECTS

Use of survey tools for documenting existing objects. Introduction to the use of laser scanners and photogrammetric methods.

8. DIGITAL REPRESENTATION

Drawing and modeling software: usage and fundamental concepts; raster and vector representations, graphic primitives, 2D and 3D spaces.

Graphical interface: command input methods, drawing visualization tools (zoom, pan, aerial view); precision drawing (object snaps); two-dimensional graphic primitives; selection set management; editing graphic primitives. Object properties (color, line type, thickness); use and management of layers; use and management of libraries and blocks; use and management of hatches; dimensioning. Output devices for printing; layout usage.
