Orthographic Drawing Year 8

“Orthographic” drawings show 3-D objects from just one angle – at 90 degrees – To do this we need 4 views - but often use fewer. We use enough to give all the important details we are going to use.

Orthographic drawings allow other people to construct your ideas. Important details and measurements are easily checked

Let’s assume Winton School want to market a new product – models of your favourite teacher - like ‘action figures’ -

Undoubtedly the best selling one would be the one of Mr Richmond. Here is the first most important view. We should draw some construction lines so that the different views line up So which view goes here – which way does the nose point ? And what about the view here – would this look to the right or left ? This might be enough … but we should know where to add the other two views. Which view goes here and which way does the nose point? And finally what about the last view – which way does this nose point ? If we need to add dimensions then the figures are written alongside arrows that go exactly between the construction lines. So now carry on and draw your own. 70 mm 200 mm 15 mm The final layout showing all views
