Technical Drawing

Basic concepts of Spatial Geometry and the categories of solids, geometric features and properties. The concept of volumetric perception in the built environment. Representation methods. The concept of projection in Level Geometry and its Geometry Space. The method of parallel projection. The Monge System. The axonometric method projection. Methodology for designing compact and non-compact solids representations with emphasis on building applications. Application of basic geometric constructions in the representations. The use of grid and scale.

1. INTRODUCTION

• The necessity of geometric perception for the engineer,
• Solids categories in Euclidean space / properties and geometric features,
• Correlation of building form with geometric solids (volumetric perception of built environment),
• Drawing paper size categories, A4 ratio

2. SOLID REPRESENTATION METHODOLOGY

• Methodology for the representation of the outer shell of solids (plan view, underneath view, front/side/back view)
• Use of geometric constructions for the design of these projections,
• Distinction of cases with the criterion of the parallel or not of the seats to the projection levels

3. METHODOLOGY OF RESPESENTING THE SECTIONS ON SOLIDS

-Methodology for the representation intersecting surface of solids (plan view, underneath view, longitudinal/cross-sections)

4. AXONOMETRIC DESIGN METHODOLOGY

• Three dimension drawing through the axonometric presentation for the outer shell of solids, as simple building complex
• Axonometric plan / section

5. FROM SOLID TO BUILDING SHELL

• Presentation of basic elements of the structural structure of a building shell, symbolism and sequence
