Question

Creating custom .hol files but running into issues

I'm creating some custom .hol files to inserts like keenserts and helicoils. For the most part, I've got it working, thanks to the youtube channel Creo Parametric, but am running into a few problems I can't seem to find the answer to.

 

  • Can you have multiple thread series in a single .hol file? Reason being, depending on the dash of the insert, it could call for a UNC or UNF.

  • My countersinks don't seem to automatically populate when creating the hole. It seems like I have to manually click it and when I do, it doesn't enter in my diameter I put into the .hol file. Anyone have a work around to this?

No, but maybe yes.  There is only one field at the top of the hol file for setting thread series, and this is what is used to drive the series parameter used in the hole notes, so out-of-the-box, no.  On the other hand, if you're constructing your own callout syntax anyway, you may be able to add extra columns to your hol file and then reference these columns in your hole note.  You should be able to add an extra column for series and then change it row by row.

The countersink will not turn on automatically, but when you do turn it on it should automatically set itself to the size specified in the CSINKDIAM column of the hol file.  I can confirm that this definitely works correctly, so maybe double check the hol file values.

 

For reference:

"You can create user-defined parameters by adding columns to the table. The column header will be the parameter name, and its value will be assigned according to the respective row. Add the user-defined columns at the end of the list, after the system-provided columns."

    Awesome. Thanks. I'll try that. While I have you, do you know of a way to make it show limits instead of plus minus tolerances? For example, "[.3]{0:@++.006@#}{1:@--.001@#}" gives it a plus and minus tolerance (Also, I can't seem to make them stack how they would normally. Using this seems to have the +/- tolerance side by side. If you know a fix to this, I'd greatly appreciate it). Is there some black magic to show a limit? For example, the limit would be 100-82.

    Funny you should mention this, I was just having a conversation today with the product manager about this very thing.  The problem you're going to have is the values in the hole note are not dimensions, they are parameters, and you can't turn on tolerances or show limits for parameters.  You might be able to play games and manually add tolerances as dumb text (like you show above), but there is no way to automatically add limit values.  You might be able to add additional columns for each dimension's upper and lower limit, and then use those parameters instead to display the sizes, but that is going to be a ton of work.  You might be better in the long run to just give up on the hole notes and show the actual dimensions instead.
