Issue:
In certain standards, threads must be rounded or chamfered. For example, as shown in the figure below.
Why do none of the thread types in ZW3D include these features?
Causes:
The thread can be divided into 2 types: theoretical thread profile & design thread profile.
Below is a comparison table of these 2 thread types:
| Feature | Theoretical thread profile | Design thread profile |
|---|---|---|
| Purpose | Reference / ideal model | Manufacturing / real use |
| Geometry | Perfect, sharp corners | Radii, flats, tapers |
| Tolerances | None | Included |
| Reality | Unachievable in practice | Fully achievable |
Currently, ZW3D only supports the theoretical thread, which doesn't have any additional features.
If any design thread is needed, a customization is a must.
