Hi @ercwtsnHDS,
Thanks for jumping in and letting us know your findings, much appreciated. As @sabadell mentioned, we have a few things to sort out as we continue to expand this feature over the coming months. Here's some initial responses. Looking forward to your input. Also happy to chat directly if you prefer.
1. Leading zero issue is logged (FDWG-12788) and our team will be looking into it.
2. Countersink angle issue is logged (FDWG-12782) and our team is already working on it.
3a. Are you wanting the leader to point to the center of the circular edge in top view (see yellow highlighting in the images below), or the entry point of the hole in side/section view (see orange highlighting)? Or both 😉?


3b. Can you expand on the "neither does it recognise the centerline" comment? I'm not sure I'm following the workflow, more specifically how a centerline, center mark or center mark pattern selection places a hole and thread note.
4. Can you expand on this? I think you're referring to the Close/Normal/Loose fit within the Hole dialog? If yes, are you expecting to see +/- or min/max values for the selected hole diameter within the hole and thread note?
5. Correct, this is not supported at this stage. We have a lot of work to do to support modelled threads. How often are you using modelled threads versus cosmetic threads?
6. Correct, this is not supported at this stage. How often would you require alternate unit display on hole and thread notes? If switching Dimension Units (within Document Settings) switched hole and thread note units, would that satisfy the request?
7. Correct, this is not supported at this stage. Do you see this as a option within Document Setting, meaning it would apply to all hole and thread note within all sheets in the document?
8. Correct, this is not supported at this stage.
As I mentioned above, we are continuing to expend support for hole and thread features. In the coming days we'll be starting work on external thread support, improved selection/highlighting of holes and hole patterns and other minor enhancements. And once that's done, hole charts.
Anyways, hope this helps and looking forward to hearing your thoughts on the questions above.
Cheers, Andrew
