section line with single arrow
in
also, what is the current correct term for the line used to show where a section is being made.
helpful sw websites every user should be aware of
i have seen this used consistently on architectural drawings, but never on mechanical drawings.

i believe it is "cutting plane line."
but i usually use "section line," which is the term the asme std's use for what i call "cross-hatching," which is referred to by solidworks and auto cad as "hatching."
the use of a single direction of view arrow on a mechanical has been noted to be used with half sections. however, it has been my experience that this is not common. a direction of view arrow is usually shown at either end of the cutting plane lin.
according to multi and secional view drawings asme/ansi y14.3 - half sections are defined as passing two cutting planes at right angles to each other, through the object so that the inter-section line of the two cutting planes is coincident with the axis of symmetry of the object. thus, one-fourth of the object is considered removed. when the cutting planes are coincident with the center lines, cutting plane line, arrows and section letters are omitted.
the spec has not record of the above method. although, it's close to a removed section which has no arrows. a removed section has no projection and sits along the cutting plane.
