Orthographics Projection - Engineering Drawing

Engineering Drawing with Orthographics Projection

1. Orthographics

2. Orthographics Orthographic drawings are used to show 3D objects as a set of 2D drawings. Orthographics are used by architects, engineers and designers every day to help them visualise their work.

3. Orthographics Learning Intentions Understand the purpose of orthographic drawing Apply drawing boards skills to produce various orthographic drawings Communicate various objects clearly through drawing Evaluate my own and others work to provide effective feedback Success Criteria Participate in class discussions on purpose of orthographics Produce orthographic drawings of objects 1-9 Use of correct drawing standards and conventions Complete self-evaluation after each drawing Complete peer evaluation at halfway and end point of topic

4. Orthographic Views The orthographic views show different planes (sides) of the 3D object. The front of the object is known as the Elevation. The top of the object is known as the plan. The left and right hand sides of the object are known as End Elevations.

6. One last thing… The word “ orthographic ” comes from the Greek words “ orthos ” which means straight and “ graphé ” which means drawing . The word was devised by the Roman architect and engineer Marcus Vitruvius Pollio who lived in the first century!

7. Page Setup Whether the orthographic has been produced manually or on the PC, certain items must always be on the page. Title Block Scale Projection Symbol

8. Peer Assessment Use the ideas below to help you give feedback to your peer You have used your drawing equipment well Your construction lines are light Your drawings are all in the correct position You have labelled your drawings correctly, in block capitals You have a dark outline around the finished drawings Your title box includes the drawing name, scale and 3 rd angle projection symbol Next time try to make your construction lines lighter Remember to outline the finished drawing Make sure you use the 45 set square to draw the bounce line Hold set square on sliding rule for straight, vertical lines Use block capitals to label each part of the drawing
