Tapped holes in mirrored parts disappear

Tapped holes in mirrored parts disappear

Tapped holes in mirrored parts disappear

(OP)
I had an assembly inside which I wanted to mirror certain components. These components both had tapped holes in them which were created using the threaded hole type in the Hole command (not pre-NX5 hole command).

The components seemed to work correctly, but I noticed that the while the hole mirrored over, the symbolic thread did not. What is the problem with this? Did I miss something or is it a glitch?

RE: Tapped holes in mirrored parts disappear

Ross mirrored body will always work so should instance geometry. With mirrored features some things may need to be taken care with. Check that the draft is applied before the mirrored feature set and added to the list of features to be mirrored. It generally also doesn't apply to all instances where you may have expected mirrored instances to be included in that selection.

Best regards

Hudson, I did that mirror with the Mirror Assembly command. Sorry if I didn't explain that properly. I have a group of parts that have opposite-hand versions. I thought that it may be easier to just mirror them over instead of re-creating them.

No Ross my apologies. Must be going blind as well as stupid, I read tapered for tapped.

Try again...

Mirroring only ever takes or took the geometry and tapped holes don't get carried across. With mirror assembly sometimes  parts that are otherwise symmetrical about at least one axis may be repositioned rather than mirrored. When this isn't geometrically possible a new part is created with physically mirrored geometry, and that will consistently fail to carry the thread features with it as it does in any other setting within UG.

Yes I would say it might make a good enhancement request, if it isn't already under consideration.

Regards

Thanks for your input Hudson. I have contacted the re-sellers about this and logged a call. Hopefully it will make an appearance in a future version. Here's hoping, anyway...

This has ALWAYS been the behavior when mirroring symbolic threads and we are aware of this issue, but I have no information on when and/or how we intend to address this.

Hi John, fair enough. I just can't understand why mirror doesn't mirror everything. I come from a SolidWorks background and know that when you mirror components you get the tapped holes too.

RE: Tapped holes in mirrored parts disappear

Well if you use Mirror Feature the Threaded Holes will be handled properly, so perhaps this could be an alternate approach:  Create the right-hand part, create the left-hand using Mirror Feature (select all the features).  Create 2 Reference Sets, Right and Left, and then in your assembly use whichever one you desire.

RE: Tapped holes in mirrored parts disappear

I found that I could go to the mirrored component and add the symbolic thread using the Thread command. It is a bit of a double-up, but at least I was able to sort something out instead of creating the other one from scratch. Thanks again

I Actually use the associative copy / instance geometry to make an array of a threaded hole and in the result the thread representation is gone, only the hole is create.

I think it mignt be some to add to those kind of feature (mirror instance) there is still thing to improve one those ones.
