✔✔Phantom line - ✔✔Medium series of one long dash and two short dashed, indicates
alternate position of parts
✔✔Long-Break Line - ✔✔Thin solid zigzagged lines, used to reduce the size of drawing,
✔✔Short-Break Line - ✔✔Thick solid zigzagged lines, indicates a short break.
✔✔Cutting or viewing plane line - ✔✔Thick solid lines with arrowheads, indicates
direction in which section or plane is viewed.
✔✔Offset cutting plane - ✔✔Same as cutting plane, not symmetrical
✔✔orthographic drawing - ✔✔Two or more views, each showing a complete picture of
the object from that point.
✔✔Auxiliary View - ✔✔Shows the true shape and length of an inclined surface or other
special features.
✔✔Sectional View - ✔✔Clarify internal or hidden features
✔✔Phantom view - ✔✔show alternate position
✔✔Exploded View - ✔✔Shows relative location of parts
✔✔alignment diagrams - ✔✔Used when an alignment check on an aircraft is performed,
to clarify points
✔✔Station diagrams - ✔✔Orthographic views, showing the location of structural
components
✔✔schematic diagram - ✔✔The relation of parts within a system
✔✔Tolerance - ✔✔The greatest permissible error
✔✔Bend Allowance (BA) - ✔✔The amount of material used in making a bend. The
distance between tangent lines.
✔✔Base measurement(BM) - ✔✔Outside dimensions of a formed part
✔✔flat (F) - ✔✔Flat portion of a formed part
, ✔✔Mold Point (MP) - ✔✔intersection of extension lines outside formed part
✔✔Mold Line (ML) - ✔✔An imaginary line that runs between mold points
✔✔Bend Tangent Line (BTL) - ✔✔Indicates the beginning and end of a bend.
✔✔setback (SB) - ✔✔The distance from the bend tangent line to the mold point
✔✔Neutral axis (NA) - ✔✔An imaginary line near the center of the metal. Always
remains constant and will never shrink or stretch

✔✔Scribe - ✔✔Sharp steel prick
✔✔Dividers - ✔✔used for laying out arcs or circles on metal
✔✔Prick punch - ✔✔Used for reference marks, makes light mark for hole centers and
center of arcs. Point sharpened to 60 degree angle.
✔✔Center punch - ✔✔Marks hole locations for drilling, prevents drill from wondering.
Point sharpened to 90 degree angle.
✔✔Drift punch - ✔✔Used to finish driving out a bolt, pin or rivet from a hole. (Flat points)
✔✔pencil compass - ✔✔Used when drawing arcs, curves, circles, and when bisecting
lines
✔✔triangle - ✔✔Used when drawing vertical or diagonal lines.
✔✔tinner's snips - ✔✔Cuts up to 1/16 inch in straight lines.
✔✔Aviation Snips - ✔✔Cuts up to .050 inch, has small serrations on cutting edge.
