Abstract
Technical drawing of a prefabricated reinforced concrete staircase flight in isometric perspective, a method used in architecture to represent 3D objects on a 2D plane.
Extract
[...] It is commonly used for 3D mass plans, morphological analyses or detail drawings, particularly in normalized technical representations (cf. ISO 5456 standards). -The isometric perspective is a particular form of axonometric perspective in which the three axes are inclined at 120° to each other, corresponding to a 30° inclination on the horizontal axes with respect to the projection plane. (Technical Drawing Manual, Architectural License Course L1-L2) The isometric projection is very commonly used in technical architectural drawing because it is simple. [...]
[...] In fact, here, all dimensions are represented at real scale on the three axes, without deformation, which facilitates reading, taking measurements, and modeling simple volumes. 2-Graphic Part: The work to be done concerns the provision of a technical drawing defining a prefabricated reinforced concrete staircase flight. We have produced on A3H format, the isometric perspective of this staircase at a scale of 1:10. We have taken into account the reduction of the fleeing lines 1:1. The pricing of this perspective has been carried out. The pencil refinement has also been done. Finally, all hidden edges have been represented. [...]
