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