Tangent lines on Isometric views
Tangent lines on Isometric views
(OP)
Hello,
Is it standard to keep tangent lines shown on isometric views? Please see the sample file attached. For this particular part, it doesn't seem like it adds clarity by keeping the tangent lines. It seems more confusing for me to have them, but that could just be me. I typically prefer no tangent lines, but according to Y14.4M-1999 section 3.4 Fig 16c, tangent lines (phantom lines) are acceptable as a substitute.

I will say this about the drawing you link, it seems as if phantom and hidden lines are a bit mixed up, it's difficult to tell what's going on.

Well it should ... "if it adds clarity"
RE: Tangent lines on Isometric views
Perhaps if they were shut off it would be easier to read.

I agree with you that it doesn't add any clarity for the most part based on your sample.

(Of course, not where I work when I was checking which made it fun).

RE: Tangent lines on Isometric views
Thanks Kenat...I think I just needed to know that others agree with me. When I'm challenged, it makes me question myself if I am doing it right or am I just being petty.

Most people didn't like me pointing out their mistakes either and I am of the male persuasion though fairly young and inexperienced (by checker standards). However, my immediate predecssor was retirement age and they didn't like him pointing stuff out either.
I think Engineers are worse than designers/drafter but I don't have a large enough sample size to say that with much confidence.
That said, the lead systems guy was over asking why everyone here is so resistant to doing tolerance checks, I told him I didn't know (although I shared a few theories) but that they were like that with me too when I was checking.
3 years is pretty good going though for this to be the first to question every redline
Good luck, keep fighting the good fight.

But back to OP. Our cad system is defaulted to show tangent lines, there visible lines not phantom lines. In the drawing i posted, which ISO would you prefer to see on a drawing if you building this part? (I removed the dimensions from the print) Remember also, ISO view are for clarification on complicated parts sometimes. We don't use ISO view's unless for clarification of the part.

RE: Tangent lines on Isometric views
The cad system I am most familiar with (Pro/E) gives the ability to show only selected tangent lines. I use this method to show features that would otherwise not show up clearly.

Agree with Peter that ortho views rarely benefit from tangent lines.
But that's just my 2C. Management types will like #4 most because it's prettier.

RE: Tangent lines on Isometric views
I prefer #4, but would not reject #2 if the smooth edges were a thin weight.
