You might already know this, but in solidworks the geometry is infinite even if the line doesn't show up that way. To me, infinite lines clutter up an assembly or a part if you have to turn that sketch on, and there is no way to change a line from infinite back to finite- at least not in 2008 sp5
Been a bit since anyone posted, I am running SW 2012 and still don't see that this is added as an option. I can do the macro as suggested, but it would be nice if it were a checkbox option. Anyone know if it is and I am just missing it?
