Block I 2D. Flat geometry. |
I review of previous knowledges.
Conical: definitions, focal and main circumferences, tangent line and normal in a point, tangent lines from an external point, own and improper.
Tangencies between straight and circumferences and between circumferences (26 cases).
Tools of resolution: geometrical places, operations of dilatation and investment and power.
Technical curves:
Trochoids: definition, traced and tangent line in a point.
Other technical curves.

Block III. Normalisation. |
Generalities on the drawing: - The drawing like language. - Types of drawings: technicians and artistic. - Technical drawings: architectural, topographical and industrial. - Industrial drawing: *Croquis, conjoint diagrams, *despieces and geometrical drawing.
Normalisation of the drawing: - Advantages of the normalisation. - Difference between regulation, specification and norm.
Basic normalisation: formats, writing, types of line, scales, etc.
Representation normalised: - basic Principles of representation. Methods of projection - Seen. Seen particular: auxiliaries, interrupted, partial, local, turned, etc. - Courts, Sections and Breaks: Specifications, types of cut, sections (knocked down, displaced), etc. - *Rayado of courts: types of line, orientation, etc. - Conventionalisms: symmetrical pieces, repetitive elements, details, intersections, parts *contíguas, etc.
*Acotación: - General principles of dimensioning. - Types of *acotación. Classification of the heights. - Principles of *acotación. - Elements of *acotación: Lines, extremes of lines, *inscriciones, etc. - Forms of *acotación: series, parallel, by coordinates, etc. - *Acotación of particular elements: radios, diameters, spheres, arches, symmetries, chamfers, etc. - Threads and threaded unions. Elements of a thread. Threaded elements. Classification of the threads. Representation of the threads. Threads normalised. - *Acotación Of threaded elements. - Designation of the threads.
Drawings of group and *despiece: - Rules and agreements: reference to elements, material, numbering of planes, examples. - *Acotación Of groups. List of *despiece.
Systems of tolerances and superficial finishings: - Types of tolerances: dimensional and geometrical. - Dimensional tolerances: linear and angular. - Tolerances ISO: qualities, positions, types of adjust, etc. - Systems of adjust. Examples. - Indication of superficial finishings.
