DimArea Text Alignment Unexpected Behavior

Hi all,

I found some unexpected behavior when trying to center justify text with the DimArea command.

When I change the text justification, I can see that the control points move, but the text remains unchanged.

Here are three screenshots that capture the issue, and an example file below.

Hei Alexander -

Yea, I see the points getting repositioned but when you deselect and reselect, they are back where they ought to be.

Apart from that, it doesn’t make much sense to align/justify anything to just itself. If you add another line to the text, the alignment is as expected.



Hi Wim!

(Always good to hear from you)

I was expecting the center align to change the text so that it aligns onto the leader line… but I can see now that the leaders are really intended to be used for horizontal alignment only.

This little tick box for a Landing was a nice solution for me:

Hei Alexander -

That does make those leaders clearer, yes.

I’m not sure if you’d want the text to be vertical, but that’s also possible:
