ASME Y14.2M,Y14.3M SECTION LINES

[tap90291]

Can anyone shed any light on section lines. According to y14.2m 1992 edition on page 1, section 2.5 Section lining is defined as "Section lining is a pattern of straight, equally spaced, parallel lines used to indicate the cut surfaces of an object in section views (see figs 1. and 2.)." Can this be viewed to allow a hatch pattern for steel or stainless steel's like what is shown in eddition 26 of the machinery's handbook pg 608 showing a PATTERN OF parallel lines but are not equally spaced between each line. I am working on a DOE project and we are splitting hairs, but I do need to know what is acceptable. The figs referred to in the specs only show uniformly and equally spaced parallel lines (not patterned) would be the same as the fig in the machinery's handbook for cast and malleable iron or general us of all materials.

You are confusing the section line (used to indicate where the section is cut at) with the crosshatch lines (used to show that you have placed a section through material).

Look at Y14.3, page 18, you can see the section lines and the corresponding section view with the crosshatching.

The section lining I am refering to is the actual hatch pattern.

Different materials can be rendered with differect "section lining" (crosshatch) patterns, or by simply changing directions of teh patterns. It all depends on what standards (ASME/ANSI, SAE, ISO, DIN, DOD) you are required to follow.
