I've just opened an assembly drawing (originally created in SolodWorks2003, SP5.1) in SolidWorks 2004, SP2.1 and have encountered the following problem:
Although the Exploded View definitions and Exploded Line sketch entities were error-free in 2003, the converted assembly and the drawing did not behave properly.
One of the explode steps that moved a group of 4 instances of a single type of screw got messed up. Two of the screws were shifted to a different distance.
I attempted to edit the Explode step and it made NO difference. I deleted the explode step and the four screws remained exploded.
It wasn't until I edited the Explode Line sketch to delete EVERY line associated with the screws that I was able to redefine the Explode step and then recreate the Explode Line sketch entities.
In the case of this example, the "error" was rather easy to notice, since the assembly is just a small number of components. What concerns me is the potential for similar Explode View/Line corruption to occur with other more complex assemblies in which the misalignments could go unnoticed.
In any event the time needed to rework a previously completed assembly was frustrating.
Have others seen similar regressions?
