Talking about the times before CAD era and digital designs, engineers and drafters had to produce the technical drawings, documents, and designs - manually. The lines, shapes, curvatures, surface finish, manufacturing processes, everything had to be inserted manually and it was a really tedious task.
However, with the advent of AutoCAD, SolidWorks, Inventor, Creo and other CAD software, the game completely changed. The drawing and drafting process became easier than ever, and became more accurate and reliable and gradually; today we have a single source of truth to refer designs for everyone right from design conceptualization teams to ERP division processionals.
Enlisted are some of the major aspects in mechanical product designs and development phase where the CAD plays an important role.
1. Drawing to Scale Size
The biggest advantage of CAD software probably is being able to sketch the components and part drawings with enlarged or reduced scales. This feature is extremely useful in drawing & drafting parts of gigantic industrial equipment like huge pressure vessels to reduce the size to a certain suitable scale and each dimension is adjusted accordingly. On other hand, we have smaller component like drill bits and fixtures on machinery, which can be drawn at enlarged scale & size to view the smallest details.
2. Parametric CAD eases the Drawing Process
The CAD software developers like Autodesk and Dassault Systems launch new version of the existing CAD platforms in the market. Each version is better and more user-friendly (in most cases) to let the drafter or the CAD design engineer to make design layouts with a better UI. The parametric CAD software allows changing the design dimensions, and the corresponding changes in the final manufacturing or fabrication drawing will be done automatically.
3. Interoperability of CAD Platform
When manufacturers receive the final assembly CAD model to manufacture the part, not every component is modeled in the same CAD software. In fact, to keep the design intelligence covert, parts are purposely modeled in separate CAD software and assembled. Earlier, with manual drawing, it was difficult to keep the design secrecy. But now CAD platforms have better interoperability amongst them to enable cross platform data transfer without the loss of data. Different layers of the model are identified ideally, enabling the editing as per the designer’s convenience.
4. Better Adherence to Drawing Standards
For industrial components and products there are several internationally accepted set of standards like ASME, ANSI, BS, etc. With the varying standards we have different value of tolerances, fits, limits, and all the other design and manufacturing allowances. Manually, taking care of every small dimension is critical especially in case of multi-component assembly. While with CAD, the preset measures and features, adhering to varying design and drawing standards can be diligently taken care of and uniformly maintained across the designs - part or assembly.
5. Accuracy and Efficiency in Geometry
Manual methods are always prone to human inaccuracies and hence will inevitably have errors. On the contrary to this, CAD eliminates any design inaccuracies other than the wrong input. It helps you create customizable lines, spheres, circles and other geometrical shapes ideally and copy the design features between two open CAD files.
Outsource your 2D Drafting & 3D Modeling
Despite all these benefits, there are market players who claim CAD platforms are very costly and depend on their legacy design data on papers documented with them since decades. However, proper research will help you locate the best CAD vendor or CAD consultant who will help transform the legacy design data to and help you preserve it. No need to find CAD services near me, or CAD designers near me, as we are just a click away from you.
