Nice idea—thanks. I’ll try it.

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.<br class="">
<br class="">
Is there such an option? Of course a workaround is to give \ncline{C}{D} linestyle=dashed, but the standard picture is to only have a break near the crossing, otherwise it is simply a straight line.<br class="">

You can achieve this effect by drawing each node connection using two passes. On the first pass, draw a white curve about 2pt wider than your standard curve width, and draw the real node connection on the second pass. This can all be put into a small macro,
for efficiency.<br class="">
