Thanks Chris&Joel

@Joel
Mabay I make a mistake.
I have an empty sheet.
Ruler = pixel.
Grid matrix = 100 px.
subdivision = 10 px.

I create a line with point in the middle.
The lenght is 200 px.
I move the middle point some pixel.
I change the midpoint in inspector with the arrow from 0 to 50 pt by corner radius.
I use this in the top of inspector labeld stil > lines and form.
50 pt the maximum ????
I cannot change this to 200 ?
