=Orthographic / Isometric projection and Scale=

===Orthographic and Isometric projections are important methods of representing a three dimensional object on a two dimensional surface. They can exist in a freehand sketch style (like the example above) or in more formal scaled and measured drawings. They are key components for representing the ideas of the architect to the client, builder, and others involved in the design process.===

Learn the techniques of orthographic and isometric projection for communicating the ideas.
Learn basic mechanical drawing techniques. Understand the concept of scale in architectural drawing Introduce digital 3d modeling

**Content to be explored:**

**Activity 1 - Basic Orthographic projection ( teacher led activity)**
Watch the demonstration of orthographic projection drawing. In your sketchbook and using the object provided: measure all of the dimensions of the object in a **SCALE** of 1:1 (1" = 1") Create a **free hand** orthographic sketch making sure to place your views in the proper relationship on the page.
 * Step 1**
 * Step 2**


 * WHAT IS A SCALE?**
 * A SCALE IS THE RATIO BETWEEN THE LINEAR SIZE OF THE DRAWING TO THE ACTUAL OBJECT BEING DRAWN. IN THIS CASE THE SCALE IS 1" = 1" OR FULL SCALE. SO EVERY 1" ON THE DRAWING IS THE SAME AS 1" ON THE OBJECT.YOU WILL LEARN MORE ABOUT THE DIFFERENT SCALES IN THE ACTIVITIES BELOW.**

Create a **measured** orthographic drawing in a scale of 1:1 using your t-sguare and triangles on 11x17" paper. Make sure that you include a border and a title block on your drawing. The title block should include the course name, the title of the drawing, the scale of the drawing, the date and your name. Your drawing should have four views: a front view (elevation), a plan view, a side view (elevation) and a section view. Dimension your drawing Photograph your drawing and post to your e-portfolio. Place your original drawing in your cardboard portfolio
 * Step 3**
 * Step 4**

**Activity 2- Basic Isometric projection ( teacher led activity)**
Watch the demonstration of isometric drawing using the object provided and using the measurements from activity 1 on 8.5x11" paper draw the object in an isometric view Make sure that you include a border and title block and all the information as you did in Step 4 of Activity 1 Photograph post to your e-portfolio. Place original in your cardboard portfolio.

Activity 3 - Architect's Scale and 3d modeling in google sketch up
Click on the link below and watch the video on reading an architect's scale rule. Fill out the worksheet ( ask for the handout) to test your knowledge Reading the Architects scale rule.
 * Step 1**


 * NOTE: THERE IS ONE PIECE OF INFORMATION IN THE VIDEO THAT YOU SHOULD DISREGARD. ALWAYS GIVE YOUR DIMENSIONS IN FEET AND INCHES LIKE THIS: 2' - 6"**

Click on the link this link. Go to SketchUp playlists, then select the "Getting Started" tab. Beginning sketch up tutorial 1 Watch the tutorial on basic tools and concepts of google SketchUp. Open the SketchUp program on your desktop and use your ipad to watch the tutorial as you follow along. Pause the tutorial as needed.
 * Step 2**


 * BEFORE YOU CONTINUE: MAKE A FOLDER ON YOUR DESKTOP AND LABEL IT WITH YOUR FULL NAME AND THE TITLE MEDIA STUDIO -ARCHITECTURE. PUT THAT FOLDER IN THE DOCUMENTS FOLDER. PLACE ALL OF YOUR SKETCH UP FILES IN THAT FOLDER. DO NOT LEAVE ANYTHING ON THE DESKTOP.**

Using the architect's scale ruler and the object that you used for the previous activities. In google sketch up you will create three separate drawings at the different scales. The scales you will use are: 1" = 1'-0", 1/2" = 1'-0" and 1/4" = 1'-0". When you complete your drawing take a screen shot and post to your e-portfolio.
 * Step 3** ( The first drawing will be teacher led, the next two will be done independently).



Activity 4 Creating orthographic drawings in Layout.
Step 1 Create a new file. Cut and paste the model of the object at 1'= !'-0" into the new file Step 2 Create scenes in Sketch Up Step 3 Create a drawing page template in Layout Step 4 Export your model to Layout Step 5 Create a set of orthographic drawings on a single sheet and print. ALSO TAKE A SCREEN SHOT OF YOUR SHEET AND UPLOAD TO YOUR E-PORTFOLIO

Project - Gawlick Room
In this project you will build on your skills and knowledge of orthographic projection and scale.

Step1 Using a tape measure (not an architect's scale) you and a partner will record the real dimensions of the interior of the Gawlick room. The Gawlick room is at the end of the hall on the west end of the building. You must include all of the permanent dimensions of the room including any door or window openings and any other built in or attached features. Include the length width and height of the walls. You do not have to include the ceiling or anything attached to it. Your dimensions must be accurate to within a 1/2". Record this information in your sketchbook (use small freehand diagrams see the image below) or on piece of graph paper, so that you can use it in the next step. Photograph this document and post to your e-portfolio



Step 2 Step 2 of this project should be done individually.

Taking the dimensions in Step 1, create an orthographic projection **including a section view** in **1/2" scale** on a sheet of 17x22" drawing paper. In this activity you will be drawing the interior of the room Make sure to create a border and title block and enter the information as you did in the previous activities. Make sure you lay out your drawing in advance and according to standard practice. Your drawing should include a top view, front view and one side view.

Below are two links which contain a lot of information on basic drafting standards. Use them as a reference for this and subsequent projects. While there is more information here than you need for this project, take some time to look through this carefully.

Drafting Standards Prezi on drafting standards

Step 3 Watch these videos on model making. In particular, note the technique of scoring - in order to create corners. model making part 1 model making part 2 Pair up with a classmate. Together, make a chipboard model of the room in **3/4" scale**. Include a floor and all four walls (with any openings) and any other **permanent** features that you have discovered. ** Do not ** include a ceiling for your room.

===**It is important that your model be accurate and neat. Make sure all of your walls are square and parallel. If you are using adhesives of any kind, make sure that you use no more than is necessary and that you remove any drips or globs of glue**===

Step 4 Watch and follow along with the tutorial Beginning Sketch up tutorial #2

Step 5 Using the same information you have previously gathered you will create a 3D model of the Gawlick Room in google sketch up.

Step 6 After you have finished your model, rotate around your model and select three different views. Take screen shots of all three views and post to your e-portfolio.


 * ASSESSMENT:** **Make sure you have all of the activities and the project uploaded and properly labeled to your e-portfolio. Activities are scored on a scale of 1-10 (10 being the highest) and in total will count for 40% of your total grade for the unit.**
 * The project is scored on a 1-10 scale as well and will count for 60% of your total grade for the unit.**

**Activity 1 - Basic Orthographic projection drawing of wood block -manual**
