Technical Drawing

Ever since i can remember i have drawn within the lines. a single line out of place and i would not be able to complete the drawing because it would bug me to the point of near insanity. I've realized that i was more fascinated by the lines themselves than the picture, thus began my love of geometry. I've always been especially good with numbers, specifically the fact that there is no guessing - there IS a right answer.

For this blog i am reading a book titled Technical Drawing: Presentation & Practice by Engr Segun R. Bello. This book is not quite a beginners level understanding of it, so while i will have the different methods i used to draw certain figures, i'll leave out the 'boring' equations.

I am going to mainly be focusing on improving my visualization of every day things, seeing how they work, why they look the way they do, and how i can draw it. You'd be amazed how much parabolas show up in nature.

This blog seems to be a lot of information, and little entertainment thus far... so let's begin

Fibonacci series

the Fibonacci series is a series of numbers where each number equals the sum of the previous two numbers. example: 1, 1, 2, 3, 5, 8, 13. when graphed it takes a spiral or a "whirl" shape to it, which is most famously seen in pine cones

to draw this, i used a series of boxes gradually getting smaller as they descend down the curve created by a series of hexagons and squares tilted by approximately 20° 

in the book, it states," Principal lines are sketched lightly using a number of short strokes. once the joining points have been established and lines are satisfactorily straight, they may be darkened as needed to give complete emphasis"(Bello 7.5). I am not used to doing a practice run before the finished design, so tracing over the lines i want will be new to me.

This is the finished principal lined drawing. you can see all of the boxes and angles, as well as the 20.6cm circle it was drawn within. 

This part is much harder in my opinion. It takes a lot of standing back and looking at it to remember exactly which lines need traced, and when using a permanent marker a single messed up line could potentially ruin the beauty of the pattern.

Thankfully i'm not reading a book on coloring the photos. I was planning on coloring it in a rainbow pattern on the curves to show it better, but as i finished i noticed this 3-point clover like shape, which i have found in other drawings. this show's that there are correlations between so many random things in the world that anyone can see, you just have to be looking. 

these other two drawing where not made similarly at all, yet have the same inner shape 

I think the biggest strength i had was with making the larger shapes. Once it got down the smaller lines however, it became increasingly difficult to line things up. with the inner two rows of boxes you can see that they are not quite consistent enough in the shape of them, and the occasional line does not actually match up in the location it should. I will probably use a finer tipped maker/sharpie in the future so i could possibly add more detail as needed. I think that i was rushing too much as well, i got sloppy which is not a good thing to do when dealing with math. i will give myself more time to do the projects in the future.

has seeing these shapes be combined to make art changed your opinion on geometry or math in general?

Materials used:

• Compass
• ruler
• sketching pencil
• black marker
• a piece of paper

NOTICE: no actual pine cones where harmed in the making of this drawing 🎄
