2D and 3D CAD Drawings and Modelling for an Effective Presentation

CAD drawings or computer-aided design are drawings done on computer software which can modify, analyse, or optimize a design. CAD software enhances the designer’s productivity, the quality of designs and their accuracy is improved, additionally CAD can also help with buildings information modelling which can have a significant positive impact on the longevity and quality of the building. CAD drawings have use in various fields apart from buildings and architecture, such as electronic systems (where it is known as EDA or Electronic Design Automation) and mechanical designs (where it is known as MDA or Mechanical Design Automation).

CAD drawings replacing traditional drafting

When software for CAD drawings is used for architectural or mechanical designs they either use vector based graphics in order to mimic and enhance the traditional drafting objects which show how the overall appearance of the designed object would be. CAD designs should display not just the shapes but also convey information like the materials, dimensions, processes, and tolerances. It can be used in the designing of curves and figures in 2-D space or in the 3-D solid. Three dimensional rotations are possible with modern CAD packages allowing objects to be viewed from any angle.

CAD Software – used in a range of industries

It is used extensively in aerospace industries, shipbuilding, automotive, architectural and industrial design; prosthetics etc. CAD drawings are also used in creating special effects in movies and advertisements. Additionally CAD is used in the designing of machinery and tools, designing of buildings (be it residential houses or industrial and commercial structures like factories and hospitals). It is also used during the entire engineering process which includes the conceptual designing and layout of the product, through the entire process of the dynamics and strength analysis and the defining of the manufacturing process of the components. Not only does it provide the above stated uses but also it provides advanced animation and rendering capabilities to the engineers so that they can visualise the design of their products or buildings.

Faster, more accurate designs

One of the significant advantages of using CAD drawings for the design of your building is that the design will be more accurate, using computer modelling rather than a pencil and ruler it is also a much faster way of creating designs and architectural blueprints. 3D CAD drawings also have the benefit of being easier for the client to visualise and for the design team to work through any potential issues with.
