I suggested it because it requires no memory<br>> and it expresses the relationship that a CoordNode is<br>> a NumberNode.<br><br>OK, my reason for prefering the bit flag is that it allows to change <br>a normal coord to a "NumberCoord" without allocating a new object.<br>I think that makes life easier.<br><br>> <br>> > 2) Is a CoordNode always also a number node?

But otherwise it is from number node to number node.<br>> Arc is a NOD concept, house numbers are purely a NET concept. I know<br>> that we don't support a NET only build but if we did it could have<br>> house numbers without any routing at all.<br><br>OK, I may try to code the support for NET without NOD later.<br><br>Gerd<br></div> </div></body>
