Dear All,
With commands such as
\pnode(-2.3,0){U}
\pnode(-2.3,3.4){V}
\ncline[linewidth=0.2pt]{<->}{U}{V}
\ncput*{$h_{_a}$}
I get the label at the right place.
And with
\rput[c]{57}(2.84,1.88){$\frac{r_{_b}-r_{_c}}{2}$}
the label is rotated. Fine.
But if (U,V) is not a vertical/horizontal line I have difficulties
placing the label in a rotated position. Please consider
\pnode(0.94366,2.10268){U}
\pnode(5.78241,3.8267){V}
\ncline[linewidth=0.2pt]{<->}{U}{V}
\ncput*{$h_{_b}$}
Is ok. But to have the label rotated I did
\pnode(0.94366,2.10268){U}
\pnode(5.78241,3.8267){V}
\ncline[linewidth=0.2pt]{<->}{U}{V}
\ncput*{\quad}
\rput[c]{27}(3.40,2.99){$h_{_b}$}
But this is not elegant (it is awful).
How to proceed in such cases?
Thank you.
Luis
