Technical drawings are an important aspect of engineering communication. They are one of the best ways to accurately and unambiguously capture all the geometric features of a product or a component. When using CAD software to design parts, creating technical drawings is relatively straightforward.

Step 1: Create a Drawing From a Part/Adding Views

To begin drawing, create a drawing from your part in Fusion 360. Change from the Model environment to the Drawing environment by clicking "Model > Drawing > From Design". Select the part you'd like to draw then press "OK". You'll be taken to a new tab with your new drawing prepared.

If you move your mouse around the drawing, you'll find that you're already dragging around a view of your part. To place this view, click somewhere on the drawing; conventionally, you'll place the first view around the bottom left. After you've added the first view, you can add additional views by clicking "Projected View", selecting the base view, and moving your mouse to the sides of the base view. Click to place these additional views.

To add isometric views, click "Projected View", then move your mouse diagonally from the base view.

To add a cross-sectional view, click "Section View", then choose a view from which to take a cross-section. Select two points to form a line, then press Enter. The new view will display your part as seen when cut along the line you defined.

To add a detail view, click "Detail View", then choose a view from which to show details. Click to choose the center of the detailed circle, then click again to choose the radius. The part of the view inside the circle you create will be used to create an enlarged, detailed view.

Technical drawings are intended to communicate all features of a part, often so that the part can be replicated accurately. Include as many views as necessary to achieve this goal and accurately communicate all of the part's features.

Step 2: Dimensioning a Drawing

Once you've added enough views to capture the part, you can start adding dimensions. Dimensions communicate the size and shape of your part. To add a dimension, press D or click "Dimensions > Dimension". This tool will select the appropriate kind of dimension for any measurement on your part. The tool works in exactly the same way as the dimension tool for modeling. However, unlike the modeling tool, this dimension tool does not set dimensions. Rather, it displays existing dimensions from the part.

Step 3: Drawing Standards

In general, follow the drawing standards and dimensioning guidelines given in the image above. By following these guidelines, you can create professional-looking, clean, and easily understandable drawings.
