The real issue is the inability to restrict the dimension to one of the cardinal planes. For example, I want to show the distance between two points in the Z direction only, even if the points do not have the same X or Y value. This is easy in the UI - it likes to “snap” a dimension to one of the cardinal planes. But it’s not possible with the API.
Oh, I understand what you mean now that you actually explained it.
But looking back up at the original thread, there are quite a number of different dimensioning issues discussed. Originally, this thread was about dimensioning to objects inside groups. So, my response to your recent post, was correctly answered against the original question of this thread.
The official API issue tracking is done at the GitHub tracker, as you well know as this is where you filed the request to enhance API definition of dimensions:
It is probably better to discuss this feature there, where you already asked the question that popped into my mind whether LayOut dimensions could do what you desire.
I know you’ve been waiting 6 years for this feature. There are features we’ve been waiting 16 years for.
