Hm. I came up with def draworiented expr c = path _c_ ; _c_ := c ; do_draworiented enddef ; def do_draworiented text t = draw _c_ t ; drawarrow subpath(0, length(_c_)/2) of _c_ ; enddef; which works, although I have to do draworiented (reverse p1) Is there an easy way to have it work with draworiented reverse p1 ? -- Giuseppe "Oblomov" Bilotta _______________________________________________ ntg-context mailing list ntg-context@ntg.nl http://www.ntg.nl/mailman/listinfo/ntg-context
