I use Solidworks 2004 SP 3.1 to do thick film Hybrid layouts. In these layouts I have to produce wirebonds to show how each IC is connected with a .001" wire. I make an assembly that consists of all the components, and then I add a new part called wirebonds. I then edit the wirebond.sldprt within the assembly and create a 3D sketch,(spline) with a .001 circle mated to the spline and make surface sweep for each wire bond. But today when I tried this SW would let me create the first surface sweep, but when I try to do the next wire bond the 3D sketch, (spline) does not show up until I zoom way out. I have done this for months, but now today I cannot get past the first wirebond. Could SP 3.1 have had an effect on viewing 3D splines?
Thanks
