Modify hole values 2

[Hayden]

Hi all,

I want to addd the dimensions of a threaded hole to a family table. ie. M16, pitch 2, tap drill size....I can't do this however as they are not modifyable values.

The only way I can find to modify a tapped holes thread size is to redefine it. This in itself is fine too, but I'd like to be able to put the tag for that paramater for that thread size on my family table.

Has anyone worked out how to do this?

Cheers in advance

Hi Hayden,
Have you thought about a UDF for the hole and manually adding the parameters for the UDF to a table?

cheers,

Udf's aren't really something I'm conversant with. I've done using a cut and then a cosmetic thread though. It works fine but I want to be able to suss this one out for the sake of knowledge. I've found that there are actually hidden parameters in the hole feature.
I've tried to apply these to a relation so I can drive them but I'm not too sure how this can be done, the parameter is THREAD_DIAMETER. How, though would you apply that so that the relation knows which thread diameter top pick up on. Ie if you have two threadrd holes in your part.
I tried things like:
THREAD_SIZE=id_xxx(THREAD_DIAMETER)
THREAD_SIZE=feat_id_xxx(THREAD_DIAMETER)

No matter what I couldn't get anything to work.

Hayden,
This is just a guess; have a look at the syntax used in the .hol files. I am assuming that you are using the hole feature to create your threaded holes? You might be able to drive your table based on the data stored in these files. I am assuming here-that I understand fully what you are trying to do.

When you are adding an item to the family table, pick Parameter from the Family Items dialog box. Then in the Menu Manager that pops-up below, pick Feature then the hole you wish to add parameters to the table from. A list of parameters with check boxes will appear. You can do this with any hole features because the FID will be assigned. Hope this helps.

CardenasR,
Thanks for the tip-had no idea you could access thread parameters so easily through family tables.

I tried what you are saying CardenasR, but alas, couldn't get it to work....yet. When I go into the instances, the values stay the same as for the generic. I'll keep on trying though and hopefully get there. Thanks for the tip.
