An engineering drawing is a type of technical drawing that is used to convey information about an object. A common use is to specify the geometry necessary for the construction of a component and is called a detail drawing.
ISO 13567 is an international Computer-aided design (CAD) layer standard. ISO 13715:2017 Technical product documentation — Edges of undefined shape — Indication and dimensioning ISO 15786:2008 Technical drawings — Simplified representation and dimensioning of holes
The [main] field of the drawing, as opposed to other areas of it, such as the parts list , general notes (G/N), flagnotes , title block , rev block , bill of materials (B/M or BoM or BOM), or list of materials . Rationales for drawing changes that are noted in the rev block often use these abbreviations for brevity (e.g., "DIM 14.00 was 12.50 ...
Whereas in a conventional hand drawn technical drawing, if a mistake is found, or a modification is required, a new drawing must be made from scratch, the 2D CAD system allows a copy of the original to be modified, saving considerable time. 2D CAD systems can be used to create plans for large projects such as buildings and aircraft but provide ...
An architectural drawing or architect's drawing is a technical drawing of a building (or building project) that falls within the definition of architecture.Architectural drawings are used by architects and others for a number of purposes: to develop a design idea into a coherent proposal, to communicate ideas and concepts, to convince clients of the merits of a design, to assist a building ...
An elevation is a common method of depicting the external configuration and detailing of a 3-dimensional object in two dimensions. Building façades are shown as elevations in architectural drawings and technical drawings. Elevations are the most common orthographic projection for conveying the appearance of a building from the exterior.
A reference dimension is a dimension on an engineering drawing provided for information only. [1] Reference dimensions are provided for a variety of reasons and are often an accumulation of other dimensions that are defined elsewhere [2] (e.g. on the drawing or other related documentation).
Leite et al. [3] compared types of clashes identified in a manual coordination process (overlay of 2D drawings on a light table by pairs of subcontractors) and through automatic clash detection using a Building Information Model (BIM). The automatic clash detection identified several clashes that were missed by the subcontractors, who were ...
