Hi Phillip - Could you post a simple (a single annotation style) file that shows this behavior? I’m not able to reproduce that here so far. I see that the value is rounded but here it’s rounded to 0.001 and not 0.002.
Also, when testing the height of a text string against a style that doesn’t use as many decimals and has the same resulting text height in model space, it shows that the height of the text object is correct (i.e. not rounded).
Note that the intended and recommended workflow is that this height is set to something that is legible on a layout and that layout units typically are either millimeters or inches in contrast to whatever the model units are set to.
