The benefits of 3D CAD Models
3D design is a more complete process than 2D design and thus greatly improves the design process. As a result, the design process is streamlined and many human errors that can occur with traditional 2D design methods are avoided. Using 3D CAD models provides a number of benefits to your project which is seen by customers, stakeholders and the designers:
3D CAD modeling provides a very up to date approach that will impress and exite customers and stakeholders in a project.
Using 3D modeling reduces human error by improving the quality of the designs produced and as a result reduces the amount of rework needed. 3D design models give the designer a visualisation that is to the exact scale, which fixes problems such as component collisions, incorrect quantities and having parts that don't fit because the designer is no longer forced to mentally store this information.
Using 3D design modeling to get quantity data is easier as items are represented as they occur, consequently, as long as a CAD 3D design is created as a true to life model, the 3D modeling design represents quantities with exact accuracy. If done correctly the CAD 3D modeling method used will give details of blocks and layers (i.e. items) automatically so it greatly reduces human error when counting items. BOM and schedule generation with 2D methods rely again on mental visualisation to generate a part count, and thus human error is again a risk when quantifying. With 2D methods quantity data suffers challenges such as a particular component being shown in several views while other components might be completely omitted to maintain drawing clarity, these issues result in miscalculations when doing a part count.
Communication of design intent is vastly improved by using CAD 3D modeling. In the world of 2D modelling you often have to wait for a prototype to gain a true understanding of the design, 3D modeling has the ability to give both traditional projections and pictorial views making the design intent available to anyone who needs to look at it. This makes it possivle to promote your product design earlier in the project by sharing a 3D model, which buys and saves time. Customer presentations, brochures, manufacturing, and technical publications all benefit and become clearer.
The possibilities for concurrent engineering take a real step forward with CAD 3D design because the sheer quality of 3D design modeling data can be instinctively understood and acted on by other departments.
Computerising your models using 3D CAD software future proofs your project and design. In the future we will be able to integrate these designs into the internet allowing you to source the most cost effective materials to manufacture your design at the click of a button
2D models rely too heavily on human interpretation and visualisation, so these methods can not provide a high level of quality in most cases. It is almost impossible for a computer to extract information from 2D models and people who are not designers (i.e your customers and stakeholders) really struggle to interpret the design. Using 3D CAD models removes these challenges and makes the whole process smoother and more efficient.
