TECHNICAL DRAWING - WHAT TO GAIN FROM THINKING 3D
People in manufacturing understand the importance of technical drawings. Good technical drawings can often reduce the risk of significant delays in production as well as guard against the danger of ending up with inaccurate products. Technical drawings must be accurate, and drafted according to industry standards, whether they be for one off or mass production.
Moving from 2D to 3D CAD has allowed many successful manufacturers to expand, grow, and innovate. 3D design generates time, cost, and material savings. It also improves workflows, processes, and product quality as well as increasing creativity, inspiration, and innovation. No matter what you design, moving to 3D will help you do a better job by accelerating time-to-market. It will also improve the design for manufacturability, eliminate unnecessary costs, produce consistently high-quality products and will encourage greater innovation. With the easiest, smoothest transition path from 2D to 3D, Solidworks design software can help you achieve the productivity and efficiency gains that will enable you and your company to grow and gain a competitive edge in an increasingly competitive global market.
We have already posted about why you should think 3D before 2D. If you missed that blog post here is the link so you can check it out:
Technical drawings created on Solidworks before 2008 are called legacy drawings. It’s important to be able to convert both legacy drawings and newly created 2D drawings into 3D models. This conversion from 2D to 3D is important in aiding the visualization of the finished product. Our brains are simply better able to do this type of visualization from a 3D virtual object than they are from a 2D drawing.
While 2D drafting tools provide sufficient information about an object, only 3D modeling techniques can help engineers and designers to detect problems and provide solutions for these problems before actually building the physical object. Therefore, 3D technology provides companies with competitive advantages.
In fact, despite the importance of 3D, some CAD designers may still focus on the traditional 2D drafting systems (vector drafting), while others may use 3D design systems which deal in solid and surface models. Some modern CAD packages even allow rotations in three dimensions, allowing the view of a designed object from any angle. Most modern CAD software is capable of dynamic mathematical modeling, in which why a new terminology CADD is used. CADD stands for computer-aided design and drafting.
Converting a 2D drawing into a 3D model can be complicated, even when using popular 3D modeling tools like AutoCAD, SolidEdge and Microstation. The most important parts of the conversion process is understanding the process itself. Being well-schooled in the software that is being used. The aim of this technology is to make the process of creating 3D part models from existing 2D CAD drawings.
It's also important to realize that different types of CAD require the CAD operator to think differently about how to use them to design.
2D systems provide an approach to the drawing process that is very close to old-school hand drafting, but without concern over scale and placement on the drawing sheet that accompanied hand drafting. Computerized drafting allows scale and placement to be adjusted as required during the creation of the final draft.
3D systems require the CAD operator to use what is referred to as "design intent". Design intent refers to the process of capturing intelligence in the 3D model by means of parametric and geometric relationships that define the fit and function of the part.
The best representation that is created when design intent is part of the formula enables future revisions and changes of one section within the model to be interpreted throughout the design so that the engineer can see the results of the change in the overall design, rather than just as a basic shape change in one section. This means that the designer must consider the consequences of any changes that he makes along the drafting process.
