Learning to draw to scale, and create accurate floorplans is crucial if you are persuing a career in architecture, construction, or engineering. Floorplanner has graciously allowed us to create an EDU account (and sub-accounts) for students here. Once created, you will be able to follow the directions found on the website to create architectural drawings and floorplans. This is an introduction to this type of drawing, and should not take the place of learning AutoCad or other brand-name architectural software if you continue to work in professional trades or careers. Please review the tutorials listed below, and spend time in class learning to use the basic functions of this program. You should be familiar with how to create walls, doors, windows, and place furniture. You should also be able to render in both 2D and 3D to create images for inclusion in presentations.Tuesday, April 9, 2019

Design Layout - Rough Sketch to Scale Drawing 18-19 S1
Today will will extend out learning about Drawing-To-Scale by making some Rough Sketches of rooms in our school. Please take a moment to review the instructions about Drawing-To-Scale from yesterday. Watch the video below to help you understand how to create a Rough Sketch of a room prior to designing for that space:
When you have reviewed the information, use a blank piece of paper to create a sketch of our Technology Room. Once you have recorded the "rough dimensions" then use graph paper to create a scale drawing. See how accurate you can be, and make sure to list the scale you are working in. Turn in your work for review. If you get done early, you can work on a Rough Sketch of all the rooms around the Technology Lab for practice. Turn in both worksheets for review and credit.
HOMEWORK: Tonight you should try to visit a home improvement store (Lowes, Home Depot, True Value, or a kitchen & bath store) and look at some of the documents that are available to help you design specific spaces. Choose one type of document, and with the permission of your parents, and the owners of the store, take the documents home and work on a closet in your home. Make sure to use a tape measure to measure all the dimensions in the closet. Your next task will be to redesign a closet (at home, or at school). You can choose any design elements you wish. You must design, price, and report on what the project will cost, and an estimate of the time and materials you will use. We will be expanding on each of these requirements next week during class, and scaffolding the steps of this project so everyone can keep up. Let me know if you have any questions. Remember to follow the Problem Solving Steps we outlined in the beginning of the program. Define the Problem, Prepare a Solution, Try to Solve it, and Reflect on all steps and at the completion of the project. Have fun with this project.

Drawing to Scale & Basic Proportions 18-19 S2
Today we will be working on Drawing To Scale and Basic Proportions as an introduction to Architectural Design. Please take a few moments to learn about this by watching the following videos:
BASIC PROPORTIONS (http://www.basic-mathematics.com/scale-drawings.html)
Since it is not always possible to draw on paper the actual size of real-life objects such as the real size of a car, an airplane, we need scale drawings to represent the size like the one you see below of a van.
In real-life, the length of this van may measure 240 inches. However, the length of a copy or print paper that you could use to draw this van is a little bit less than 12 inches
Since 240/12 = 20, you will need about 20 sheets of copy paper to draw the length of the actual size of the van
In order to use just one sheet, you could then use 1 inch on your drawing to represent 20 inches on the real-life object
You can write this situation as 1:20 or 1/20 or 1 to 20
Notice that the first number always refers to the length of the drawing on paper and the second number refers to the length of real-life object
Example #1:
Suppose a problem tells you that the length of a vehicle is drawn to scale. The scale of the drawing is 1:20
If the length of the drawing of the vehicle on paper is 12 inches, how long is the vehicle in real life?
Set up a proportion that will look like this:
Do a cross product by multiplying the numerator of one fraction by the denominator of the other fraction
We get :
Length of drawing × 20 = Real length × 1
Since length of drawing = 12, we get:
12 × 20 = Real length × 1
240 inches = Real length
Example #2:
The scale drawing of this tree is 1:500
If the height of the tree on paper is 20 inches, what is the height of the tree in real life?
Set up a proportion like this:
Do a cross product by multiplying the numerator of one fraction by the denominator of the other fraction
We get :
Height of drawing × 500 = Real height × 1
Since height of drawing = 20, we get:
20 × 500 = Real length × 1
10000 inches = Real height
The whole idea behind creating a scale drawing is to keep the objects in the drawing proportionately accurate in relation to each other. By using a measuring device called a scale you can create accurate drawings of very large objects on a standard size piece of paper.
Scales Used to Create a Design Drawings
1:4 Scale pronounced: "One Quarter Scale" or One Quarter aSize.
1/4 inch on the scale = 1 unit on the object being drawn.
By extension, if we use 1/4“ graph paper, one 1/4” block can equal one inch, one foot, one mile, one light year etc. For architecture, 1/4“ usually equals 1’ (1/4 inch = 1 foot). Scaling is really up to you but be consistent with all measurements and dimensions otherwise the end result will be useless. Always note what the scale you used on the drawing and whenever possible use industry standard scales.
Engineering and Architectural Scales (in this case the word scale is being used as a noun referring to a type of measuring device) are made in a triangular form so that they can be marked with different scale ratios for versatility. Typically, a triangular scale has 12 different ratios on it - 6 on each end and related ones (like 1/4 and 1/8 for instance) interlace in opposite directions without interfering with each other. Below is what an Architectural Scale looks like.
How to Use Them
The scales on the Architectural Scale (isn’t it nice the way they make explaining this so easy:) are all related to measurements in feet and inches. Above is a representation of 1/4 scale. One quarter inch equals one foot. Notice that at the beginning of the scale the first 1/4” is divided into 12 subdivisions, one for each inch in a foot. Notice also that the ”0“ point starts after the initial smaller subdivisions. Watch out for that. If you don’t remember that the zero mark is not at the beginning of the scale you will end up with an inaccurate drawing. It is set up that way to make it easy to layout feet and inches - like 4’ 6”. The 4’ would use the main part of the scale and the 6“ would use half of the inches designation on the end. That makes laying out a drawing very easy. By using 1/4” graph paper you will greatly reduce your drawing time. The Architectural Scale will help you with the inch measurements on your design drawing.
For initial design layouts, accuracy to 1 inch is good enough. The contractor and cabinet maker will measure much more accurately, of course, but for your design drawing one inch is usually just fine.
