The advent of sophisticated computer-aided design (CAD) software brought many benefits to those in the engineering and architectural industries, and among the most notable of these gifts was a host of dazzling 3D drafting options. As a result, drafters gained access to a wide range of design tools that were unthinkable with traditional 2D drawings; today, both 2D and 3D drafting remain viable options for designers in many industries. This leads to an obvious question: Which process is best? Naturally, there is no simple answer, as it all depends on the specific aspects of any given project. One consideration to keep in mind is that while 3D software provides additional options (and retains all the features of 2D drafting), these extra amenities aren’t always needed. With this in mind, let’s explore the various differences between 2D and 3D drafting.
Traditional 2D drafting deals solely with the x and y axes. For many purposes, this is more than adequate; plenty of drafters have over the years produced workable plans, elevations, and sections in this manner. It’s also worth pointing out that a limited number of 3D drafting options are available through the tried-and-true technique of isometric projection, which enables designers to represent objects in three-dimensions, to a certain extent. These techniques have been, and continue to be, useful in creating floor plans and views of objects from different fixed angles. If this is all that is required for your project, then 2D drafting should be an acceptable option. However, if your project involves creating a large number of individual views of a particular object, it can be time-consuming to generate them through 2D processes.
With 3D drafting, designers enjoy a variety of extra options. CAD files generated in 3D utilize the x, y, and z axes, providing users an enormously expanded range of tools with which to manipulate images. In addition, creating different views of an object is much easier. Models can be easily rotated along any axis, allowing the drafter to view the object without the depth and altitude distortions associated with isometric projection; the user also has ready access to auxiliary and section views. Users can view objects in a wide variety of styles, from basic wireframe to highly detailed photorealistic drawings. If you need drawings that can precisely mimic an object as it will appear in its completed form, 3D is clearly the way to go.
Given that 3D programs contain all the features of 2D ones, while adding so many more options, it’s reasonable to ask why anyone would opt for 2D. One answer is that 3D drafting is significantly more costly, and for some organizations there’s simply no need to shoulder the additional expense for features that aren’t essential. 3D drafting calls for a higher level of expertise and, in some cases, more advanced hardware. As time goes on, however, the costs associated with 3D drafting continue to decrease; it is likely that these monetary considerations will pose less of a problem in the future.
