How 3D CAD models can be used in the design process

⦁ 3D CAD models can be used to replace the manual drafting processes with a more automated process, it allows you to visualize the design from different angles and analyse the feasibility of its working. By visualizing the design you can easily spot and flag mistakes in it and witness the entire design before it has been manufactured so it removes some of the need for rapid prototyping.
⦁ A wide variety of 3D software can be used for different types of simulation, mechanical design and analysis. Kinematics programs have many different tools which allow you to test the way that a part functions and allows you to see it working before it is manufactured, this can be extremely effective for spotting issues with how the parts function with each other as sometimes there are collisions in moving parts. Some of this software has a tool called the mechanism tool which will automatically tell you if it thinks the parts are not interacting with each other as they should.
⦁ Parametric’s can be very effective in changing a 3D model with ease as you can make the 3D models driven from an external program. An example would be using the equations in a spreadsheet to change a model, the main advantage of this is that when the 3D model is driven it can be done so that when you change one dimension, the rest will change to suit it.
⦁ You can show materials of any part in an assembly after you have set the material, the material properties are true to life and more properties such as weight and strength of material can be applied. This is very important when designing for example, a part for the exterior of a sports car as it should be fairly lightweight but should also be strong enough to reduce the impact force on the driver it a crash occurred.
⦁ Another use of 3D CAD models are the fact that they can be easily imported into other CAD/CAM programs or imported into rapid prototyping machines. An example of this is seen in the fairly new trend of 3D printers, you can easily import any drawing and take it down to a printable scale. This process is completely automated, the 3D printer just extrudes material over time in intricate patterns and shapes until it is completed. Because this can be done at such a speed, it can rapidly reduce lead times. Once the prototype has been made you can then analyse the product to see if any changes will need to be made or to see if you think the overall design is feasible.
⦁ 3D CAD models are very beneficial for marketing and advertising purposes, this is because they are so detailed, high quality and look very professional. These 3D models can be easily read unlike orthographic drawings so are perfect for this purpose.

Impacts of a poor customer design process on customer relationships and requirements

The possible impact of a poor customer design process on customer relationships and requirements Poor design process can have serious negative effects on a company relationship with their customers. A common occurrence in business is poor communication between the customer and the business. Poor communication in the customer design process may involve improper consideration of information passed on by the customer, this means the completed product is likely to not be of the standard/specifications requested. This can be caused by lack of technical specification or the company simply not following the technical specification, this is due to the technical specification being the most important part in the design process due to it containing so much vital information. If the technical specification is not used/followed then the end product is very likely to not match the customer’s requirements. A finished product that doesn’t match the customer’s requirements will likely lead to lon

Evaluation on the impact of legislation and standards on design process

Evaluation on the impact of legislation and standards on the design process in relation to the profitability of the business Legislation and standards can impact the profits of companies in many ways, an example of this would be if O-Sep would not follow the health and safety tests on their designs then they may be fined, this would affect the profits of the company. Copyright laws on designs may also affect O-sep, if they were to design an alarm system that is based on an alarm system of another company that is copyrighted then they can be fined large amounts of money. An example of legislation in the design process that impacts the profitability of the business is EN 50131-1. This legislation states that components that are used must be classified safe for the environmental classification and must be given a security grading, this may mean that more expensive components must be used as the components must suit EN 50131-1. The design process may also be lengthened because EN 5

Hand Drawn Sketches vs Computer Aided Design

Hand drawn (sketches and orthographic drawings) One major advantage of hand drawn designs is that it does not require any special training to do unlike other processes, this means that for quick drawings in the workshop they can be completed by anyone, even if they are not a trained design engineer. Unlike some CAD drawings, these hand drawn designs cannot be tested so you cannot gather vital information such as weight and conduct strength tests like you can when using CAD, this can have a major impact on the finished product as there is a higher chance of it having to go through redesign. Manual calculation is needed to work out cost calculations which can be quite time consuming and has risk of human error. In comparison to other methods, manual drawings are extremely time consuming especially if you have to draw out parts that are very similar with small differences as with CAD you can just copy the parts and add the differences in with ease. Unlike CAD, manufa
