Question

1. What are the four different stages that engineering drawings may be used for, Give a short explanation of each stage?

2. List twenty (20) items that could be found on a typical engineering drawing?

Answer 1

Engineering drawings

It is an iterative process where all different phases help each other to complete the whole process. The first two phases are divergent in nature and rest two phases focus on optimizing the solution. Each phase is important and dependent on each other. There are challenges and benefits against each phase.

A)Below are four different phases of Engineering drawings.

1. Issue definition: It is one of the most influential phases of the Engineering drawing. It establishes the framework under which other phases are defines and evaluated. By asking the different questions against the situation problems are defined.

2.Design search: This is the phase of investigation where students primarily look for the solution of the problems. there would be more than one solution to the issues. so students investigate widely to understand the solutions option. And eventually will go for one solution involves brainstorming, understanding the different types of data It shifts the activity from the classroom to outdoor in search of the solution.

3. Design optimization: This step is to test the probable solutions. This is the phase where the viability of the solution is also measured. This is the phase where the actual solution of the issue is identified and designed that can be used for human beings.

4.Design communication: This is the most important phase where ideas are shared to use in the different processes rather than go for other inventions It communicates evidence-based, logical argument data to different phases. It guides for the future.
