Sections Flashcards
What is a sectional view?
Drawing a SECTIONAL View can show information more clearly can be very helpful. Sometimes the ELEVATION, END ELEVATION and PLAN combined still do not tell the whole story of what is going on with an object, so you need to look inside.
More detail about a section?
In a SECTION, we imagine what would happen if we sliced the object along an imaginary line and removed part of the object. When we draw what is left, the finished drawing often gives a much clearer picture of what is going on.
What are the rules for Sectioning?
• the cutting plane X-X defines where the object is to be split.
• surfaces touched by the cutting plane should be hatched with 450 lines.
• certain types of items are NEVER hatched. (you will find out which)
• the arrows point at the bit that is left.
• DO NOT include hidden detail in a sectional drawing.
