Hole Wizard Innacuracies
Hole Wizard Innacuracies
(OP)
Has anyone noticed that Hold Wizard information sometimes needs to be taken with a grain of salt. For example, a close fit for an M12 bolt equates to a 13mm hole size aaccording to the Hole Wizard. Normal fit is 14mm and loose fit is 15mm. What standards is the Hole Wizard based on?

Even if they used a standard, the question is which standard. Also, values for things like drill sizes for tapped holes can vary with material, method, etc.
Much of my knowledge of CAD is the result of experimentation. Most of the experimentation is based upon well-placed mistrust of assumptions such as these.

How about adding some to Favorites?
I completely agree with you that Wizard should include enough information without going to refer a handbook and SW is being improved by hearing a voice of users who are not programmers. I had a hole size chart on a wall, but once I added some to Favorites, I don't have to see any more.
Hole Wizard is very convenient to put, easy to modify and avoid making a mistake in a drawing. As long as C'bore is made by Hole Wizard, you don't have to type in depth. Most of time when I use "Extrude Cut", I make a mistake by typing the depth, .008" instead of .080".
RE: Hole Wizard Innacuracies
Depending on what book you look in, I have found different standards. There is ISO, DIN, etc. I am not sure where the company I work for came up with its standards. Only matches a few of the "other" standards I have seen. I agree with LoveAeris, use Favorites. The file can be transferred to other computers so everyone at your work should not have to make their own up. I prefer to use hole wizard for standard drills, counterbores, countersinks, spot faces, taps because it is normally much faster than trying to construct one on my own.

If you feel adventurous look at Thread559-63157, it was this exact problem that took us to this solution.
RE: Hole Wizard Innacuracies
Sorry, maybe too vague an explanation. The steps are: Feature Menu/Select feature/Right Click/Edit Definition.
The rest is pretty self explanatory. You can always use the help menu.
Good Luck.

For instance a #10 socket head screw csk has a default csk dia of .411. If I require the screw head to be .010 below flush the csk dia should be .428. THe "hole callout" button gives the .411 dia dimension, as if it is ignoring the .010 aditional head depth.
Counterbore depths are the same way. If you change the default depth setting the revised depth is ignored when dimensioning the drawing.
RE: Hole Wizard Innacuracies
When you set the Head clearance, make sure the adjacent box (to the right) is set to "Increased C'sink" not "Added C'bore". One enlarges the Csk dia the other recesses it.

Check out the hole wizard "Legacy" tab. One of the hole type options is "C-Drilled Drilled" which does exactly what you describe but in one operation. Helps to keep the model feature manager leaner & cleaner....and it works!!! BTW, I tried making the hole your way & it dimensioned both holes properly on my computer.

Tried the deeper C'bore on my computer & it worked fine also.
BTW, I'm running SW2003 SP0, so perhaps one of the later SP's "fixed" something it shouldn't have.
RE: Hole Wizard Innacuracies
Thanks for the tip that works great. Only problem is that sometimes we do that same thing with a tap or pipe tap at the top of the hole. :) Legacy won't do tapped holes and SW still doesn't dimension them correctly.

RE: Hole Wizard Innacuracies
No problem....you can still use the "C-Drilled Drilled" option & then add a cosmetic thread to the upper hole edge. The cosmetic thread gets added into the hole so it still helps to keep a cleaner (shorter) feature list.
Don't know why your dimensions aren't working though...mine work fine????
RE: Hole Wizard Innacuracies
I just want to make sure if you are not using "Dimension". An advantage of "Hole Wizard" is that "Hole Callout" gives all dimensions. If you use "Dimension", you have to type in, like depth, by yourself.
I have the problem too and "Hole Callout" doesn't work with the situation, while "Dimension" does.
RE: Hole Wizard Innacuracies
If you just highlight the drawing view & Insert/Model Items/Dimensions then I agree, the hole dimensions will not show???. But if you highlight the drawing view then select that views Hole in the drawing view/feature manager tree & then Insert/Model Items/Dimensions with the Dimension sub-options checked the depth & diameter dimensions do show.
Having said that I have just noticed that although my dimensions are showing, the Cosmetic Thread on my side view is not. Hmmm, maybe I should start a new "Thread" on Threads!!!
Hope I made myslf clear.
