What is sectioning?Show answer
A sectional view shows the object as if it has been cut through, revealing internal features such as holes and bores that hidden detail lines alone would make confusing. The cut faces are shown with hatching (evenly spaced 45 degree lines), and a cutting plane line shows where the cut was taken.
What is dimensioning?Show answer
Dimensioning adds the exact sizes to a drawing. Sizes are written above thin dimension lines with arrowheads and projection lines extending from the feature. Each size is given once, in millimetres, so the part can be made and checked accurately.
