[OS X TeX] crossings in pst node

[Luis Sequeira]

> In trying to create braid diagrams, I would like (in an automatic way) to create crossings which go ?over? other crossings.  That is, something like the \rput* option, that is, an \ncline{A}{B} which, if it crosses an earlier \ncline{C}{D}, dominates it, in the sense that there is a slight space around \ncline{A}{B} so that \ncline{C}{D} ?breaks? at the crossing point.  My first guess, \ncline* , has a totally different effect?the unstarred \ncline becomes totally invisible.

Use the border parameter in the ncline command, e.g.

\ncline{A}{B}
\ncline[border=2pt]{C}{D}


See page 25 of the pstricks manual.
