Patterning Holes - First Hole Repeats

[Os2man4]

I've patterned holes in my model by creating a series of geometry points in a sketch, creating a hole, and then patterning the hole using the Point reference. The only issue is that when I do that the first point that I create is created again when I make the pattern. So the first hole exists twice. Does anyone know any method or correcting this. Normally it would not be an issue, but when I go to create a hole table for the part drawing the hole shows up twice in the table and it just does not make sense from a manufacturing standpoint.


Thank you very much,


Jim

I know for this problem.
You can omit hole clicking on some of the black circles (points) during pattern creation.

vitadj - you are correct that you can omit some holes by changing the white circles to black but you can not omit the first hole in the pattern.


Os2man4 - could you post the part or make a generic version for us to investigate.

You should have the primary feature dot (black dot with a ring around it) and a instance dot almost on top of it. That is the one you want to remove.

If you do this a lot you may want to create a UDF for this. I did this and new hole sets created with the UDF omit the first patterned instance.

I haven't used pattern by point much but I believe the trick to keep the first instance from doubling is not to have a point at the location for the pattern leader.

I've always created a point, patternedit, create a hole referencing the point pattern leader then reference pattern the hole. Never had a duplicate.

I've always created my holes the way you describe. I used to Pick the second black dot of the original hole and omit it from the pattern. Then, it a later release, and I'm not sure if it was a date code or an actual release, PTC fixed it so it works the way you would expect. I believe this occurred in the second date code of WF5. Creo 1.0 works properly.

I'm still using WF2 & it works fine.

The method being used is with points in a sketch feature. This method is new with WF5.
