4. Engineering Drawing – Interpreting the drawingCopy the ISOMETRIC (3D) and ORTHOGRAPHIC (2D)views. Interpret the drawing and add the correct DIMENSIONS to the 3D ISOMETRIC view

Dimensions – sizesViews – a view from a side.Extension lines – show where we are measuring from.Dimension line – a line with arrows at both ends and a size.Plan View – view from the topTolerance – how much you are allowed to be inaccurate.Specification – the details needed to make the part.Material – What is it made fromUnits of measurement – metric system (mm) or Imperial system (inches – USA)Isometric – 3D viewsOrthographic – Flat views
