When I start a new route in piping everything works fine elbows are added correctly (45° and 90°) and radius is formed automatically.
Later on when I add to the excisting route the radius is formed still automatically however the elbows are not showing up.
The only way to have them show up again I need to delete the complete routing line and start at a connection point with "start route" and evertyting works fine again.
Radius and pipe size do match up with the design table I cannot find anything wrong, and I guess it is ok as it is working when I start.
I use Solidworks premium 2015 x64 SP 4.0
