IV2020 iPart issue

Hello, 🙂

I'm cannot work out what is causing the Thread issue in the attached iPart. When I select certain sizes I'm being told the Thread is not the correct size and having measured the Thread length which I feel is the problem the length supplied is good. If you have the part open, toggle between d=2 and L=10 and d=2.5 and L=10, that should provoke the problem.

Does anyone have any ideas?

Thanks in advance for your help.

Scott

Hi Scott,

This is an interesting issue. There isn't anything wrong with the approach you are taking. The problem here actually is with the compute sequence, not so much with iPart.

You can reproduce the same behavior by deleting the iPart table. And, then change parameter 'd' to 2mm. The same warning will come up. The warning is also legitimate because the Thread size is indeed inappropriate. Activating iPart member just facilitates the parameter change.

The issue here is that the diameter change and the Thread spec need to be changed at the same time. But, the Thread is computed after the Revolution feature.

This is why an iPart like this is better used as a library part. Fully elaborated, not subject to change. Or, you may publish it to Content Center and insert it on the fly.

Many thanks!
