ughhh... an unseemly sounding topic line, isn't it ? Sorry for
that... and also, if any other loyal XaraLX users take offense
at what I say next... but... out of sheer desparation trying
to do this in xaralx, I tried the new inksc*pe (name cleverly
obscured... only the pros will know ... and... well, version
0.46 of inkscape now does faultless snapping - multiple
lines of any kind to a common point, for instance... and even
to circle centers... how I've toiled over this one.

So... until xaralx crawls out of the bog, so to speak,
development wise, I will suggest using this other linux
scalable graphics program, at least for this kind of operation.

Until Inkscape would adopt a lot of the approach of xaralx,
I will continue to use it (XaraLX)... it is just a lot easier for
me... does so many things so well and without problems...
well, it's just unfortunate that development has stopped -
this is one of those things it could use (or... as has often
been the case... perhaps I'm just missing the easy answer ??
I'll check the tutorials for "snapping" circle center, etc).

cheers
