How can I add an "all around' symbol to the leader line of a dimension?
SolidWorks did not include this function, I expect because there is no standard for it. You can apply it to a GT&T leader or a weld leader.
I don't believe you can - at least not though SW 2014, haven't installed 2015 yet.
Randall Adams proposes applying the All Around symbol to dimensions in this year's 10 Best ideas. I've seen this proposed for a few years now, and I'll probably vote against it again, but I'd like to hear a bit more from its proponents before I do. Rather than dump on the idea directly in the submission, I figured it would be friendlier to find a previous discussion and post a reply. I was surprised to not find a good discussion about why this feature might be wanted, nor why people would rather it not be made available. So here goes.
The first image below shows the All Around symbol applied to a 1 mm profile tolerance. It means the tolerance applies all around the figure shown. If I want to spec only part of the perimeter of the figure, I can spec it between points, as for the 0.5 tolerance, which applies only between Y and Z. The 1 mm profile tolerance, though, goes all the way around.
I imagine an all-around radius might be applied as shown below for the 5 mm radius edge. Here the all around symbol is used correctly, because the radius does apply all around the figure shown. However, the radius call out is not standard.
In the example here, the radius call out is correct, but the symbol wants to have a different meaning. The radius does not go all around the figure.
Does this show the issue correctly? Are there other ways it might be applied?
it is my understanding that all around (a single circle) refers just the profile the leader is attached to. if that profile is circular, the all around condition is assumed, and the symbol is not needed. but if the profile is not circular (like in your second image), then that is where the symbol adds clarity.
And there is also all over (double circle) that would apply to the entire item. (which I believe is what you are trying to show in your first image).
I'm just looking for an example for how someone else could apply an all around symbol to a dimension. The ones I show in the images make no sense to me. I don't think either radius with an all around symbol is valid.
I really don't understand how anyone could possibly take an active stand Against including this symbol. It seems to be such a simple programming undertaking that fills a hole in the detailing universe.
It does appear to be part of the GD&T standard...
We have a major Medical Device Manufacturer as a customer that uses the All Around Symbol regularly. To me, this request falls in the same category as any other dimensioning modifier option. It is commonly used in the world, it is part of the standard, so, it should be available in SolidWorks.
Thanks for bumping this back to the top.
I agree that it should be an option. However, like all of the available options, people will incorrectly use them in places they don't belong. I'm tip-toeing out on a branch and guessing that this is the root of Dwight's disagreement about the feature's inclusion. In my day job, I too have medical device manufacturer's specking out all around / all over GD&T tolerances, but half of the time they are used incorrectly. One particular customer is notorious for this and every time we have to go to the relevant section of the Y14.5 standard and work out with him what he really wants.
Also, the all around / all over controls are available for GD&T features, where they make more sense to be commonly used. One of the only things that comes to mind where a callout like this would be useful is if you have the GD&T frame attached to a dimension and need to use that dimension's leader line to specify all over / all around.
Sorry if I'm misinterpreting your concerns Dwight.
SolidWorks does give anyone the option to use the all around symbol for profile tolerances and welds. That's available now. I would like to see how the symbol might be used for anything else. I think people have said they would like to use them for radii dimensions, and I would like to see how it might be used that way.
I tried to come up with a realistic use for this, but buried it in the middle of my last response and probably didn't explain it well.
How about something like this:
I just threw this together from the drawing I was currently working on so it may not be a good example. However, if the GD&T frame is attached to the dimension, would it be useful to be able to specify all over / all around on the dimension? This could be done by uncoupling the dimension and the GD&T and then using two leaders as well though.
Just spitballing here, I welcome any counter opinions.
The links in your post both show how the all around symbol can be applied to a profile tolerance. I have no issue there.
What I don't understand is how the all around symbol might be applied to a dimension. If I could see an example, maybe I would understand better.
I clipped 2 examples from my customer's print.
The first is a All Around Laser Beam Weld.
The second shows a radii that needs to be All Around a double-flatted round part.
The first example you gave is already a function of the weld symbol tool:
And I'm guessing that the all around dimension in the second one would have been implied without the circle. However, that may be an example of a good use for this feature.
the only applications I know of for dimension are for chamfers and radii on non-circular profiles. here is an example from a connector MIL-Spec:
I have requested this for all annotations, Around, or All around symbol for all annotations
