tangent edge visibility
on drawings is there a preferred or standard for tangent edge visibility on drawings. me personally i try to omit tangent edges (especially when they are solid lines) because i think they can add confusion to drawing interpretation and when i find it necessary will put the tangent edges in as phantom lines. if this is covered by a standard please quote standard. thanks in advance.
check out our whitepaper library.
take a look at asme y14.2m-1992 which i don't have to hand, i flicked thru y14.3-2003 but didn't see it though at least some examples seem to show tangent line as some kinf of chain line.
kenat,
check paragraph 2.11(d) phantom lines and fig. 12 in asme y14.2m-1992 (reaffirmed 2003). phantom lines are used to indicate filleted and rounded corners. i agree that they should be avoided unless they add clarity to the drawing.
i agree with the others. i don't use them unless needed.
