Hello, I have just tried to use the weld bead function. Everything is ok until I re-open the assembly with these weld beads in. They all have the traffic light rebuild symbol on them. All the in context is ok <1>-> and the welds are fixed (f) Is this normal behaviour? If it is, it's blooming pants! Solidworks office 2006 sp 4.1 Windozzzzze XP Pro Thank you. Ps I can send out the file if that would help
