I have a sketch in an assembly which is used to drive the geometry. Within this sketch I have a couple of blocks that are linked to files. These blocks are also used in various parts in the assembly so their use seemed to be a good idea. Update the block and Voila! all is well… Yea, not so much. Every time I make even a simple change the block every relation and dimension attached to them goes away and needs to be reattached. Even if I just change one dimension in the block (and thus not changing the element names) everything is lost. Is that normal or am I doing it wrong?
