UDF of Revolved Hole Placed on a Cylinder Not Working as Expected. 1

I have created a UDF of a revolved hole that is placed on a cylindrical surface and has the options to select the port size, the option to be placed on the surface at an angle, and to be offset from one end of the part. I have had to use section curves to place the revolved section sketch as I was unable to select a silhouette edge of the cylinder in the sketch. (I have tried a recipe curve which seemed a cleaner way of creating the sketch did not work properly.) In the UDF all of these options appear to work properly but when I place the UDF in a part it fails every time. I have worked in Pro/E for many years and we have recently moved to NX. We had this UDF in Pro/E and it worked properly in it but I am having some challenges getting it to work in NX. Can someone take a look at my attached model and give me some guidance on how to fix this?

Thanks,
Scott

I have modeled new hole slightly different then you did. I have started with extruded, then used tapered and counterbored holes.
UDF was created with no problem and also used with no problem.
Maybe you should change something in your udf geometry. Maybe you have to many constraints to external geometry. Therefore it is hard to pick the right geometry, when placing your udf.

I have attached one zip file containing my original part for udf creation, a movie about creating udf and a movie about using this udf.

I have created a similar model with Reusable Library.
I have attached the following in the 7zip file:
1. master file, from which the reusable object was created
2. excel file and bitmap file, which were added in the Reusable Library (the same folder as it was used for creating a reusable object)
3. I have also added the hole_tool part, that was created in the movie as a reusable object
4. the movies, that explain how to create a library, a reusable object and hot to use this object.

For this example, maybe it would be better, if I would create this hole_tool at coordinates (0,0,0). Then it would be easier to position the tool on a new model.
As it is created now, you have to know, that the tool is originaly created at the position (4,0,3). So, when I entered the coordinates (0,0,0) in the movie (03-reusable object usage.avi), I actually positioned this tool in a new part at coordinates (4,0,3).
But I guess, that for learning of this example it will be good enough.

Hope, that this will help, too.

Hello SvenBom, thank you for the two options you provided. I will probably end up using the first option you sent but I also find the second option interesting as well. I'm sure I will eventually find both options useful as we become more accustomed to NX.

Thanks again for your responses.
Scott
