show crosshairs even if not dimensioning to them?
show crosshairs even if not dimensioning to them?
(OP)
For example, I have a top view where I dimension the location of a thru hole. That view has crosshairs
Two projection views later I have a bottom view. I can now see the other end of the thru hole, but I am not dimensioning to it (to prevent overconstraint).
Is it correct to show the crosshairs on the bottom view as well? I feel it would just clutter up my drawing.

RE: show crosshairs even if not dimensioning to them?
To take your example to an extreme - we have assemblies with hundreds of holes in them. We omit center lines in these instances unless we are dimensioning to the axes. If we did not omit the center lines, the drawing would look like a spider's web.
I would let clarity dictate the use of center lines.
RE: show crosshairs even if not dimensioning to them?
Either way, I don't add centermarks unless there is a dimension to the hole because this makes it clear that there is no dim to that hole (missing or otherwise). They can also clutter the drawing if over used.

I basically inconsistently add them when I feel it adds clarity/improves the drawing.
