Learn to Draw Floor Plans
G’day I’m Kyle - I’ve decided to do a series on architectural drawing – the first part, we’ll be looking at floor plans. Over the next couple of weeks I’ll be releasing some videos to help you understand architectural floor plans from the real beginner stuff, that I quite seriously struggled to understand when starting out, to some of the more advanced tips and tricks for drawing neat, legible, sexy architectural floor plans that your teachers in architecture school will love.
If you’re not already subscribed, I recommend doing that as well as pressing the bell so you get notified when I release the next parts of this series.
First of all, what is a floor plan?
There are different types of floor plans. There are diagrammatic plans that are generally not to scale, there are sketch plans which are to scale, there are visualisation plans which showcase the quality of a space and how it’s used, then there are documentation plans which show how the space is to be built. That’s really important to know – and we’ll touch on these in late videos. Let’s keep it simple.
A floor plan is a 2-dimensional drawing of a 3-dimensional space, whether that be a building, landscape or a single room cut horizontally at approximately 1200mm or approximately 47 inches.
You might be wondering what the hell this actually means. Let’s debunk this.
Let’s first define 2-dimensional. This means a traditional floor plan has no 3-dimensional depth to it. It does not show perspective. For example, when you look around the space you’re in now, your eyes warp the space so that you can see the depth of the objects around you. There are vanishing points and horizon lines and – well – if you were to draw what you see with your eyes, you’d be drawing in perspective. But, that’s for another video.
We can’t actually see with our eyes in the same style a floor plan is drawn, that’s why it’s so difficult to grasp the idea of it.
In a floorplan, it’s as if you’re looking from directly above, without perspective. In fact, the best way to understand this is by thinking about a building. Imagine putting a horizontal slice through the building at 1200mm (or 47 inches) above the ground. That is generally where most floor plans are cut from, though this can vary depending on what you want to show.
So, you’ve taken the top off this building. Now imagine looking directly down at it. You’d still have perspective to it, as the human eye has perspective. Instead, we have to imagine looking down at it in parallel projection.
A parallel projection is a projection of a 3D object onto a fixed plane. The rays, or lines of sight, or projection lines, are parallel to each other. Rather than going out in a cone shape, they are parallel to each other. It doesn’t matter where you view the floorplan from, the dimensions remain the same. Whereas in perspective drawing, some objects would become further away and appear smaller, where other objects would become closer to the eye, and appear bigger.
We understand that floor plans are parallel projections, they are 2d drawings that are flat with no depth. We know that they are drawn by slicing horizontally through a building, object, landscape or space at 1200mm or 47 inches.
In the next video, I’m going to explain where “scale” comes into the picture. Understanding scale in architectural drawings. syhpbEjt-vg |
