CAD or hand drafting?

 

Frank Lloyd Wright drafting

A new semester is about to start and a certain topic that always comes-up is about rendering software or how we did the images on the last project. Once you get past first-year, a lot of the students are struggling to decide between hand drawings or doing work on a CAD software. As students progress through the program, there tends to be a lot less hand drawings and a lot more computer work. I mean, It is kind of understood that most (if not all) drawings used on final presentations are going to be CAD generated. Sadly, that is just how it usually goes down. I love, love hand drawings and I often do a hybrid of computer work and hand drawings in projects. After asking around, most students tend to fall back on what they know, especially during crunch time and the deadline quickly approaching. I can't really blame them. It all comes down to turning-in work you know you can produce or risk turning-in something you may not complete.
  
I am not here to say you should use hand drawings rather than CAD -- that's not the point. I do feel hand drawing isn't utilized as much these days and is a very important communication tool to learn and use. But, I also feel the evolution of architecture is dependent on technology and the software is nothing more than just another tool in the bag to use as a conduit to best express an idea. I know a lot of older professors curse the use of computers in architecture. I am sure the majority of us wouldn't want to visit a doctor if the doctor was taught and practices the same medical practice used in the 1950's, right?

Why do we always speak of hand sketching with such nostalgia? First, hand sketching is such a romantic notion. We see technology everywhere and seeing a hand drawing reminds us of bringing things back to basics. Hand sketching will always play an important role in design. It is the designer's go-to when we need to get an idea out and just 'play around' with, but that is usually where it stops. The designer has to make a decision early on that they are going to use hand drawings on their final board. Why? Because hand drawings take time and it is very difficult to fix a mistake (especially when working with drafting pens or colored pencils). CAD has a built-in 'F-it' button that we love to press because it makes our mistakes go bye-bye with a press of the button. But, CAD drawings aren't necessarily much faster either. I can easily spend five hours working on details on a drawing and most people couldn't notice much of a difference than five hours before. 

Both hand-drawing and CAD drawings take time and require layers on layers of detail. You can easily spend just as much time on one style as you can on another. Deciding which style to use is just a matter of considering how much time you can allow and how the style will work with other drawings if there are others.
