Dimensioning Hole depth on tubing
Dimensioning Hole depth on tubing
(OP)
Greetings,
I was wonder how others dimension this.
Say you have 1.00 X 1.00 X 1/8 Square tubing, with a 1/4" hole in one side (but not through the opposite side).
When dimension the depth for the 1/4" hole, do you put the depth equal to the material thickness (i.e. 1/8 DP)? Or the depth to the centerline of the tube (i.e. 1/2 DP)? or some random interval that will produce the result your looking for (i.e. 1/4 DP)?
In all cases, I think the result is the same. I was just wonder what the norm was in situations like these.
Thanks,
VS

THRU ONE WALL explains the design intent while giving instruction on what the part should be, geometrically.

As others say you put a section or maybe THRU NEARSIDE or equivalent.
Thru one wall is a CAD term that I don't like but probably works.

RE: Dimensioning Hole depth on tubing
This is why I stand behind my suggestion - if your intent may be misinterpreted - clearly show on your drawing what you want.
RE: Dimensioning Hole depth on tubing
I think that specifying "THRU ONE WALL" (which I generally use) or "THRU NEARSIDE" will suffice. You need to keep in mind, while not specified in Y14.6-2001, Y14.5-2009 ¶1.1.4 states "The figures in this Standard are intended only as illustrations to aid the user in understanding the principles and methods of dimensioning and tolerancing described in the text", and Y14.5 is part of Y14.6 (¶ 1.3).
The intent is clear and there is little chance of miss-interpreting what is required.

I've used "THRU ONE WALL" since before CAD was in widespread use.

Generally, I've seen/used "SIDE" when referring to a solid object and "WALL" when referring to tubing.
Tubes have walls (as evidenced by manufacturers usually calling out the WALL thickness) and solid objects have sides. Just seems more intuitive to me.

This is why the section view is the right way.

After 2 college degrees, a drafting certification and 10 years in the business, I have never seen or heard the use of "thru one wall" or the like..... guess thats why I like this forum so much.
In the instance that prompted this question, it is actually a small hole on one side and a large hole on the other, both concentric with each other. So for production simplicity, I want our shop to locate & drill the small hole thru first, then just come back and drill out a larger hole "thru one wall" ;) Otherwise they may end up locating and drilling both holes "thru one wall" which will take more time than needed.
The drawings for our in-house shop/factory are a quasi-drawing/work instruction all rolled into one..... fun, right?
Thanks,
