Technical Drawing Made Easy
TECHNICAL DRAWING APPLICATIONS (65)
(Candidates offering Technical Drawing are not eligible to offer Technical Drawing Applications.) Aims: 1. To develop competence among the students to pursue technical courses like Engineering, Architecture, Draftsmanship Surveying and other professional courses. 2. To understand basic principles of instrumental drawing drawn to scale and to acquire basic skills in the use of traditional drafting methods which would also be helpful in understanding computer aided designs. 3. To acquire the basic knowledge in their applications in various fields.
CLASS IX
There will be one written paper of three hours duration carrying 100 marks and Internal Assessment of 100 marks. The paper will be divided into two sections, Section I and Section II. Section I (40 marks) shall consist of compulsory short answer questions chosen from the entire syllabus. Section II (60 marks) shall contain questions which require longer answers. There will be a choice of questions. THEORY – 100 Marks 1. Types of lines (i) Border lines. (ii) Outlines. (iii) Dashed/ Dotted lines. (iv) Centre lines. (v) Extension lines or Projection lines. (vi) Dimension lines. (vii) Construction lines. (viii) Cutting-Plane lines. (ix) Section or Hatching lines. (x) Short break lines. (xi) Long break lines. 3. Lettering and Numbering
Upright capitals and small, freehand, single stroke, as used in Engineering drawing, and between, the correct guide lines.
4. Sheet Layout Basic – draw border lines, title block with name, sheet number, title etc. 5. Geometrical Constructions (a) Bisector of line segment. (b) Division of a line segment into required number of parts/ proportional parts. (c) Perpendicular and parallel lines. (d) Bisection of an angle, trisection of a right angle/ straight angle. (e) Congruent angle. (f) To find the centre of an arc. (g) Regular polygons up to six sides with simple methods using T-square and setsquares.
