Are 2D Drawings Still Needed?

Are 2D Drawings Still Needed?

With the popularity of 3D drawing and printing growing to new levels every day, it’s hard to believe that 2D was once the only way for engineers and architects to create any type of product or blueprint. 2D drawings, in their day, required the drafter to sit at a drawing board and hand draw sketches. Once the sketches were finished, dimensions were added and then the drafter would roll up the large piece of drawing paper and send it, via mail, to be reviewed by builders or machine shops.

There were many issues with 2D drawings and their dimensions that took time to fix. Layouts were tricky and if you weren’t careful, you would run out of room toward the edge of the paper. This, sadly, would result in the need to start completely over.

3D CAD (Computer Aided Design) has completely eradicated all the issues above, as the software offers many advantages for drafters. Unfortunately, there is one aspect of 2D drawing that 3D CAD will never be able to duplicate: artistry.

A CAD system does offer the ability to create a drawing in 2D, but unlike 3D drawings, users must have some type of artistic skills and ability to visualize, in order to really take advantage of 2D CAD drawings. Otherwise, these 2D CAD drawings are shaky, hard to follow, and off on dimensions. Those that draft 2D drawings, by hand or via CAD must have the ability to visualize their end results, as well.

3D eliminates the need to visualize. It also eliminates the need to draw various parts or angles of a building or product. 3D allows drafters to rotate the object and see each side, part or angle, without having to actually draw or visualize it, first.

While it might seem like 2D drawings are no longer relevant to the design world, that’s not at all the case. 2D drawings are still created. They’re still needed. 2D drawings are very different from the days before 3D, but either way, they’re relevant and used daily. Now, 2D drawings are scanned into CAD and turned into 3D models.

2D drawings are also used for inspections. Once a product or building is constructed, it’s important to make sure the parts are within the specifications set. The 2D drawing is a great way to do that.

2D drawings are used now, but there may come a day when there will be no need for them. With the rate that 3D is growing, it’s likely 2D won’t be needed in the years to come. Either way, it’s hopeful that artists and creators will understand that they’re still needed, despite the advancements and technology of 3D CAD.
