1. Front view¶
The front view is the view we choose as the main view for representing a part. It is the representation of the part as seen from the front.
The front view mainly shows the height and width of the part, but it does not show its depth.
In the three-dimensional view, the front view is usually indicated by an arrow showing the direction from which the part is viewed.
We choose as the front view the view that best represents the shape of the part, showing as many details as possible and avoiding hidden lines whenever possible.
Examples¶
In the following examples, the different faces of the three-dimensional part that can be seen from the direction of the front view are shown in red.
The edges that form the front view are also shown. These are the lines that we need to draw in the view.
In these exercises, surfaces are not drawn or filled with color: only visible edges are represented using thick continuous lines.
In the following part, the front view has an L shape extending to the left. This is the shape that we will draw in the front view.
In the following part, the front view shows an L shape extending to the left at the bottom. Above it there is a medium-sized square and, above its upper-right part, a smaller square. We will draw these two shapes in the front view.
Although the two shapes are located at different depths in the part, the front view does not show depth. Therefore, when they are projected onto the front-view plane, they appear together.
The following part has three shapes. In this case, it is important to distinguish which shape is on the left, which is on the right, and how high each one is. The front-view arrow will serve as a reference for placing each shape in its correct position.
Specifically, there is a small square on the left, located in the second row from the bottom, and another small square on the right, located at the very top.
This last part has two staircases with different orientations. From the front view, the staircase on the left appears as an L shape, while the staircase on the right shows three squares corresponding to the front faces of the steps.
