PAU Technical Drawing II (Castilla y León)

The examination is set and graded within the official PAU/EBAU procedure organised for Castilla y León by the public university system and the regional education administration. Study pages like this one are independent editorial material and have no official affiliation, endorsement or authorship from the Junta de Castilla y León or any university.

The number of exercises, the optional choices inside them and the duration are fixed for each call and can change between years. The current figures are published in the official convocatoria and in the instructions printed on the paper itself. Check the Junta de Castilla y León and university commission pages before the exam rather than relying on older material.

Standard practice is a pencil (2H for construction, HB or B for final lines), a technical ruler, a 45° and a 30/60° set square, a compass with a sharp needle, an eraser and a sharpener. Bring a second pencil and spare compass leads. Some calls allow specific items only, so read the instructions on the cover of the paper before you start.

The step up is real: descriptive geometry in dihedral projection and conic constructions demand spatial reasoning that first-year plane geometry does not. Most candidates find plane geometry and normalisation the most reliable scoring blocks, and dihedral sections and true shapes the hardest. Difficulty is largely a matter of practice volume, not innate talent.

Retake rules, the number of sittings and the validity of a previous mark are governed by the current regulations and the specific call. These are not fixed editorial facts and must be confirmed with the official convocatoria or the admissions office of the university you are applying to. Do not assume that a mark from a previous year carries over.

Start with plane geometry constructions and tangencies, because they build instrument accuracy, then conics, then dihedral geometry of point, line and plane. Move to solids and sections only when intersections are automatic. Finish with axonometric perspective and normalisation, which reward speed more than insight, and keep a weekly slot for full timed papers.

The usual causes are poor line hierarchy (construction lines as dark as the solution), missing or wrong labels, tangency points not marked, imprecise compass work, and a solution drawn outside the space indicated. Examiners grade the drawing as a document. Practise finishing each exercise cleanly, with the answer clearly identified, rather than rushing to the next one.

Use them as timed simulations, not as reading material. Draw every exercise to completion with instruments, then compare your construction with the standard solution and note exactly where the process diverged, not just whether the final line looked right. Keep an error log by topic; the same three or four mistakes usually account for most of the lost marks.

The convocatoria published each year by the Junta de Castilla y León, together with the information issued by the university commission responsible for the PAU, is the authoritative source for dates, paper structure, scoring and any changes to the syllabus. Consult those pages directly; this page deliberately does not restate figures that change from call to call.
