From Manual Drawing to Solid Modelling
Technical drawing is the precise 1. r of objects, structures, or systems useful in technical, engineering, or architectural fields. In drafting, objects or structures are generally 2. s down and represented from multiple 3. p to make their depiction as detailed and accurate as possible. The use of 4. c systems such as CAD has solved problems related to inaccuracy and precision and has improved every 5. m stage. Starting from the CAD drawing, 6. C is the following step that tells the operators how to manufacture the object; in fact, any design contains a set of physical 7. p that will be used by a CAM system to create the item. A further development is the 3D solid 8. m, the process of developing a multi-faceted 9. s using specialised software which facilitates the process of designing complex machine parts, systems, and equipment. Its most important advantage is that engineers can virtually create a product, make 10. s, analyse, and modify it before producing it.
