All good engineers need to be able to communicate their ideas clearly. Sometimes this means writing detailed reports or giving presentations. Often, clear communication starts with a good sketch of the object you’re working with. In this unit you should be learning:

- How to use concept sketching to share ideas
- How to draw carefully with oblique, isometric, perspective, and multiview sketching
- How to use sketching to illustrate the solutions to problems

In practice, good sketches help engineers remember ideas and share their solutions with other engineers. As we practice our sketching skills in this unit, you’ll go through three major steps:

- STEP 1: Practice concept, oblique, and isometric sketching
- STEP 2: Learn about perspective sketching and multiview sketching
- STEP 3: Brainstorm and draw a solution to a problem

When you’re done, you’ll have five different ways you can sketch your ideas as you continue your engineering work!

Good sketches help engineers communicate. As our class in Engineering & Design gets started, it’s essential that we start with good sketching and drawing skills. In the first part of this unit, you’ll start by practice three types of sketching: *concept* sketching, *oblique* sketching, and *isometric* sketching.

Concept sketching is used to give an overall idea of an object or solution – they are easy to label and give the viewer a sense of dimension. Oblique sketching focuses on a main front face and creates a subtle illusion of depth. Isometric sketching is more mathematical and gives the viewer a clean view of the front, right, and top faces of the object. In this part of the unit, you’ll practice all three!

Sometimes, sketching with oblique or isometric perspective doesn’t quite do the job. In instances where we want to demonstrate more precise depth, perspective sketching will be the right tool. Other times we need to be able to show details on multiple sides of an object – in that case, multiview sketching will be best. In this part of the unit, you’ll learn about perspective and multiview sketching and then get practice with each of them!

Engineering is all about using math and science to solve problems. As we start to look toward the details of the engineering design process, we’ll finish our unit by using our sketching skills to illustrate our thinking. In this part you will work to identify a simple problem you encounter on a regular basis. Then, you’ll brainstorm possible solutions for that problem. Once you’ve settled on a specific solution your job will be to draw it using at least three of the sketching techniques discussed. We’ll be sure to label the important parts of the solution and then we’ll be able to share it with other engineers.

**GRADING & PROCESS**

Identify a problem you want to think about and define it clearly in your engineering notebook

Brainstorm at least 10 possible solutions to your problem and write down your ideas in your notebook; then choose one of those ideas to draw

Carefully sketch your solution idea in 3 ways, using a different sketching technique each time
