A perspective view is an artistic one that represents an object as it seems to the eye.
It is important to distinguish the isometric view from a perspective view. Which means you can use a ruler and the scaling of the drawing to easily measure the length straight from a paper drawing, for example. The lines that are vertical and parallel are in their true length. All the vertical lines stay vertical (compared to front view) and otherwise parallel lines are shown on a 30-degree angle. Isometric drawings show parts as three-dimensional. Bear in mind that adding views should follow the same logic as dimensioning – include as little as possible and as much as necessary.Ī tip for good engineering practice – only include a view if it contributes to the overall understanding of the design. So let’s take a closer look at the different types of views that are often present in a manufacturing drawing. Here you can see that the A-A cutting line brings both types of holes into the view. When using a cutout view, the cutting plane lines show the trajectory of the cutout. Otherwise, the manufacturing engineer has to reconstruct the whole part from the measurements.

While a good way for giving information to people, CNC machines need full views in order to cut the parts. If you have a part that is 3000 mm long and 10 mm wide with symmetric properties, using a break-out makes gives all the info without using as much space. The dimension line has two arrowheads between the extension lines and the measurement on top (or inside, like in the image above) the line.īreak lines indicate that a view has been broken.
Showing symmetricity can reduce the number of dimensions and make the drawing more eye-pleasing, thus easier to read.Įxtension lines annotate what is being measured. For example, hidden lines may show the length of an internal step in a turned part without using a section or a cutout view (we explain both later).Ĭentre lines are used to show hole and the symmetric properties of parts. Hidden lines can show something that would not be otherwise visible on the drawings. The line thickness varies – the outer contour uses thicker lines and inner lines are thinner. Put simply, these lines are for drawing the objects. This represents the physical boundaries of an object. The most common is a continuous line, also known as a drawing line. The different options make it possible to show both visible and hidden edges of a part, centre lines, etc. Not every line on an engineering drawing is equal. A single drawing includes many elements with quite a few variations to each of them. Let’s see what makes up an engineering drawing. Basic Components of an Engineering Drawing Having models also makes updating the drawings for revisions simple. All you need to do is add the dimensions. But the easier option is to first make a 3D model and create the drawings from that, as the programs generate the views with only a few clicks. You can, of course, use CAD for making drawings from scratch.

So, we are left with only one option really – every engineer should use CAD (computer aided design) software because of its many advantages.

Drawings done by hand would just add a lot of manual work for manufacturing engineers. Why? Because most of the machinery uses CNC systems that can read the information straight from the files and produce a cutting program accordingly.
Today, all these instruments are still good for manual drafting but no contemporary manufacturer really wants such drawings.

How to Make Drawings?Ī few decades ago, you would have had to sit down at a drawing board covered with papers of different size, rulers, callipers, etc. Still, knowing all the rules and basics of formatting is an absolute must in the industry, as traditional manufacturing companies still need detailed drawings. The only time we ask for a drawing is if you want to specify tolerances. CAD files and drawings made according to our design tips include all the necessary information for making your product. The drawings you submit for instant pricing and manufacturing in our system do not need any of this. So once a manufacturing engineer gets the drawing, he can start the production process without a second thought.įirst, we have to pause for a second and address our own customers here to avoid confusion. The info includes dimensions, part names and numbers, etc. V What Does the Future Hold? The Purpose of Engineering DrawingsĪs already said, such a technical drawing has all the information for manufacturing a part or welding and building an assembly.
