Wrong thread visibility in NX8
Wrong thread visibility in NX8
(OP)
John,
What is your opinion from the following situation?
NX8.0 in English (metric)
Create a part file with a small cylinder (dia.20x50)
Put a symbolic thread to the cylindrical surface
Create an other part file with a small block (100x100x100)
Create an assembly part file and assemble the two above files together
Make work part the small block component
Create a WAVE link from the small cylinder (use the body and copy thread option on the WAVE dialog window)
Subtract the linked body from the block
The result is a small block with a threaded hole
Create a drawing file from this small block
You can see the threaded hole in the drawing view but the visibility is opposite to the threaded standard. The result is wrong.
When I was a Solid Edge support engineer I met this problem in the Solid Edge Mold Tooling application case. That mold application was very good 3D product but every drawing file were wrong because the Mold development used this linked threaded body - subtract commands combination. Nobody didn't buy because the customer uses hard-copy on the shop floor. The Mold development said to me that they logged this problem to the Solid Edge development but Solid Edge development replied that they don't want to repair this bug. So, the Mold development had to find any other way.

RE: Wrong thread visibility in NX8
If it is just a plate with a threaded hole, I would not use any linked data between the bolt and the hole.
If it is a situation where the threaded hole is made at the assembly level, then I would link them.
Model your assemblies like your manufacturing assembly process so your components can be reused in different assemblies if possible.

RE: Wrong thread visibility in NX8
I spend 11 years with SE and NX as designer and support engineer. I know it is not too much but I met lots of not too clever users. Sorry it is not true that they are not too clever they only use their minds simply. These users will see the Threaded possibility in the dialog window. they will try and they will be surprised the result.
I hope it will not be true but I think there will be some GTAC logs from this problem. And I think the developer team is able to write the correct boolean method with thread option.
