how to draw orthographic projections

1. Draw orthographic projections Communication

2. How our teaching resources are designed for the classroom

3. I can draw a simple orthographic projection.

4. construction lines orthographic represents a 3D object in 2D, where views are projected from the object's surface used to plan out and position elements of a drawing isometric a 3D representation of an object where sides are drawn at 30 degrees

6. Key features of an orthographic projection Features of an o rthographic projection: m ultiple views - front, side, plan (top) scale and proportion - drawn to a consistent scale ensuring accurate size and shape drawing conventions - three views, centre line, hidden lines, dimension lines and alignment no perspective - a flat 2D drawing of a 3D shape annotation and labels - material notes and manufacturing intentions construction lines - used to make sure all 3 views are aligned and the same size

7. Key features of an orthographic projection d imensions multiple views front, plan, side 3D view Which of the following is not a feature of an orthographic projection?

8. Below is a building block. We see multiple sides because we see in three dimensions. To draw in orthographic we need to identify each of the three dimension views.

When you look at a shape from the side, plan or the front there is no depth, it looks completely flat. side plan front

9. Key features of an orthographic drawing An orthographic projection must include perspective. Orthographic projections are completely flat and show no depth. Why?

10. Key features of an orthographic projection Create a simple shape using basic building blocks, sketch out the front, plan and side views. Don’t worry about the size or position of the drawings. L abel your drawings with the front, side and plan view. Repeat this for two more shapes.

13. Draw an orthographic projection Setting up your page to draw an orthographic projection. front view plan view side view The most informative and clear side can be selected as the front view. all orthographic projections follow the same layout the front view is drawn first the distance between the views should be equal

14. Using an isometric drawing as a starting point - draw an orthographic projection. 1) Label the front, side and plan view. f ront view plan view side view 2) D raw the front view in the bottom left hand corner.

17. t o help you draw straight lines t hey make sure each view is aligned and the same size t o divide the page into equal sections Draw an orthographic projection What are c onstruction lines used for in an orthographic projection?

18. Draw an orthographic projection Draw an orthographic projection of a cube. Front view Plan view Side view Isometric view Check list: all sides are the same size c onstruction lines used to show alignment views are labelled

19. Draw an orthographic projection Front view Plan view Side view Isometric view Check list: all sides are the same size c onstruction lines to show alignment views are labelled

20. 2) D raw an orthographic projection for the shapes below. Autodesk screenshots reprinted courtesy of Autodesk, Inc. Draw an orthographic projection Check list: start with the front view in the bottom left of your page draw c onstruction line s vertically from the front view to the plan and side views ensure all drawings are the same size

22. Draw orthographic projections Orthographic projection represents a three-dimensional object using multiple two-dimensional views, including the front, plan, and side. The drawing process begins with the front view positioned in the bottom left, followed by using c onstruction lines to align the plan and side views to ensure accuracy. Hidden lines or details should be represented with dotted lines, and all views must be the same size, which can be checked using a ruler.
