Attached is a drawing and model for a part. In that part a hole was created using hole wizard for the hole and an extrude for the c'bore.
This model was then passed on to the detailer who then used "hole callout" to dimension it because it looked like a C'bored hole.
When you do this however it does not reference the "hw" references created in the hole wizard because they don't exist. Instead it plops in the text of those dimensions.
There are several things I find disconcerting about this.
1) It's text...in a dimension...placed by SW, with no warning...really?
2) That text, mysteriously with no indication is linked to the actual hole. If you change the hole it updates.
3) That text link can be broken, look exactly the same as it did before it was broken and give no indication it was broken.
I messed with this for quite a while this AM. You can use "hole callout" on pretty much anything, extrudes/holes, Extrude/Extrude, Revolves and the dimension appears the same as it does with a HW hole. However when you examine the actual dimension text it plops in the dim and does not reference any linked dim. All of the above issues will then exist.
This seems like it's either missing the 5% that actually links the dims the same as it does when hole callouts for the HW or that it should at the very least throw up some sort of warning that your dimensioning a non hole wizard hole with a hole callout. Or it simply should not work, period.
This just seems broken to me and at best a half assed attempt to fix it by throwing in some mysterious link.
So I sent this into my VAR and the response was "Yep that doesn't work the dims aren't linked". The "Fix" was to add reference dimensions to each diameter and then dimension the hole with a note that links to the reference dimensions and then hide the reference dimensions....rinse and repeat for 50 holes....uhhh no.
So for anyone out there that has an engineering dept larger than one where designs are done by one person and the detailing done by another here is what I suggest.
If you're modeling a hole that is not a standard C'bored or similar hole.
1) if at all possible use C'bore in the hole wizard and modify with custom dimensions.
2) If you're making any complex hole that may be mistaken for a C'bored or standard hole that can't be made with a modified hole wizard hole use advanced holes, which hole callout annotation will not "Magically" dimension with potentially non linked dimensions
In any case where you revolve, extrude or almost any other combination of hole making the hole callout annotation is fragile at best, broken at worse. The only way a person detailing the hole would know that this hole is not a hole wizard hole would be to examine the model. Of course there is nothing indicating that something is wrong that you should examine the model. The only thing you might notice is that qty of holes does not transfer which it does with a hole wizard hole.
There is also nothing indicating that you have broken the fragile link. If you edit the dim and accidentally alter the "Linked" text dim there is no warning like there is with other <hw> links, it just breaks the link and you will never know.
