Technical product documentation — Organization and naming of layers for CAD — Part 2: Concepts, format and codes used in construction documentation ISO/TR 13567-3:1999 (withdrawn September 2015) [3] Technical product documentation — Organization and naming of layers for CAD — Part 3: Application of ISO 13567-1 and ISO 13567-2
FreeCAD is a general-purpose parametric 3D computer-aided design (CAD) modeler and a building information modeling (BIM) software application with finite element method (FEM) support. [4] It is intended for mechanical engineering product design but also expands to a wider range of uses around engineering, such as architecture or electrical ...
As a necessary means for visually conveying ideas, technical drawing has been in one form or another a part of human history since antiquity. The use of these early drawings was to express architectural and engineering concepts for large cultural structures: the temples, monuments, and public infrastructure.

[1] The interlocking design provides a way of maximising the space given to flats in any building volume by reducing the space needed for entrance corridors and providing a ...
ISO 10303 can represent 3D objects in computer-aided design (CAD) and related information. Due to its ASCII structure, a STEP-file is easy to read, with typically one instance per line. The format of a STEP-file is defined in ISO 10303-21 Clear Text Encoding of the Exchange Structure .
In solid mechanics and structural engineering, section modulus is a geometric property of a given cross-section used in the design of beams or flexural members. Other geometric properties used in design include: area for tension and shear, radius of gyration for compression, and second moment of area and polar second moment of area for stiffness .
To conserve space, some sofas double as beds in the form of sofa beds, daybeds, or futons. A Kubus sofa by Josef Hoffmann (1910) A furniture set consisting of a sofa with two matching chairs [17] is known as a "chesterfield suite" [18] or "living-room suite".
