Use of Centerlines 1

[dust237]

Scenario:
Creating a side view of a plate with holes in it. The holes go straight through the plate. The holes are fully dimensioned in the top view.

Question:
Is it necessary to draw (create) centerlines for the holes in the side view?

Seldom used a chisel point, just kept the point sharp.

Chisel point worked good for me too...

Back to the OP.

I'm not even sure which standard you'd look for this in. Doesn't sound like a 14.5 type of thing, not in 14.3 either.

I go with ewh rule of thumb that clarity is king, if they are needed for some reason, put them on. If they just add clutter then leave them off. In a case where they aren't clutter but aren't really needed, I'd lean toward leaving them off just to save a little effort, though it may be more traditionally correct to put them in in this case.

KENAT,

Have you reminded yourself of faq731-376 recently, or taken a look at posting policies:
