A recent addition to our team suggested this:

As an alternative to the Hole & Thread Tool.
This dimension was created using the following steps:
- Use "Retrieve Dimensions" to get the "DIA 20.000mm +0.2/-0.0" Dimension
- Then edit the dimension in the text editor and once you've figured out which parameters drive the hole feature, add them and the relevant symbols in the same pattern/layout as the Hole & Thread tool.
- Add the parameter value(s) that drive the 45° countersink
- Profit?
I would like the Hole & Thread tool updated so that producing this type of dimension is less of a chore.
Thanks,
Alex.
