Is there a way to dimension chamfers like in the second pic below so that the values update. You can do a linear dimension and then alter the text and try and find that dimension in the list, but the chamfer tool works well with two clicks but you only get it with a leader. I would like the same function but with a linear dimension sometimes. It would be good if you could choose it. 45° is probably not a really good example, but the leader version is not always so clear.
I think you'll just have to place a linear dimension and edit the text to add the angle. I haven't found any method to create a chamfer note in this way. Unfortunately, like you mentioned, the angle will not update automatically.
