On Libre Draw, I cannot change the default text size on dimensions

As I’m facing a, “too big default text/font size on dimensions” issue, could you pls help me on modifying the object called Arrow Line? As, after a detailed search, it looks that this is the issue-problem.

I accessed the relative menu from Lines → Arrow Styles, but there are only different arrow shapes to choose from, nothing about text, text size, etc.

Thanx in advance

In Styles pane in the Sidebar, right click on Arrow Line style, click Edit Style, select the Font tab and change the size there.

Save as template if needed for future documents.
.
[Edit]
If other lines or shapes text sizes are also too big, then you could instead change Graphic to a smaller font size and Arrow Line which is on the same tree will inherit it.

Thank you very much EarnestAI, I think that I solved it

(in my version I had just Modify -which I thought that it was about the Arrow Line-, not Edit Style…)

That would be before version 7.6 I think. It might be worth considering an upgrade to a later version

The site font confuses things, but the username is EarnestAl not EarnestAI. As in lower case ell, not upper case eye.
