Document Regeneration

floretti — Wed, 21 Sep 2022 03:51:49 GMT

Hi and thanks for reading it.

We have a need to reload a large number of families in projects and despite not having the project open in the UI, each family we reload seems to trigger the regeneration, which is causing the process to take up to an hour and sometimes more.

Is there currently a way to stop the regeneration process? We are using Revit 2019 and 2022. Thank you.

I remember discussing this recently, but I am not sure of the result. I asked the devteam for you.

There used to be a manual mode I think there is still a demand for the manual regeneration mode especially when adding or editing a large quantity of elements.

However, my instinct tells me they will not bring it back because they've since added features that expect regeneration after a transaction commit. In short, I think the automatic mode made it more predictable for them in terms of determining what state the model was in. Otherwise they have to regenerate the model before inspection of an object not knowing if it has just been regenerated and perhaps then also requiring a transaction to regenerate it (which leads to the old automatic transaction mode).

Yeah, I found some old posts and a wish list item for it that got discarded due to low community interest unfortunately. I'll wait to see what comes back from Jeremy and move on based on that. Thank you.

The development team reply: I don't know that there is such a way. And should not be, probably. If the UI is any better, we could look at the API and see if/why it does or does not behave the same way.

Thanks for reporting back, Jeremy. It's a very inconclusive answer to be honest, which leaves me the option of either keep on researching or accept it as it is. Thanks either way for taking it to them.
