Aligned Dimension Corrupts

I find from time to time that dimensions in layout space will sproing out of place with the activation and deactivation of a detail window. I have only noticed it with aligned dimensions and angular dimensions. It doesn’t happen with every object, but it does with the one below. No plugins active. Gif and project below.

Hello - it looks like that dimension is indeed corrupt in that its History is somehow broken - does not update - I’d love to know how to make this happen. The flipping does not occur, here, so far though. If you HistoryPurge that object, I would guess it will no longer flip, but of course it will not have history either… I’ll try to reproduce.
@djhg Can you please select this dimension in the original, full, file and run the What command and post the output here?


History - as far as associating dimensions goes, really isn’t useful for me. It’s so easy to breaks that I end up selecting all dimensions for fear of forgetting one if I am moving a detail view. Of course that breaks them all. Maybe the workaround is to just turn it off.

it’s wortyh mentioning that this issue cropped up just over two years ago, and it occured with the dimensioning of any block. Apparently it was subsequently fixed. There’s a post from back then documenting the issue.

Here’s What:

Thanks, that does not seem to have anything un-expected, to my eye anyway, I was hoping to see something ugly in the bit about History.


Update. It’s happening on another dimension on this project, also. Neither aligned nor angular.

Happening to me also over the long period. No pattern observed - seems random. Very annoying and workflow breaking.
