I have this situation. I created the part ( Part1) knowing that there will be a few different configurations of this part, then assembly with this part as a first component. Then I crated a new component (Part2) in context. After I add some equations to link a Part2 dimensions to some of Part1 dimension , so if I change those dimensions in Part 1, Part 2 will be updated automatically. Works fine when I update dimensions manually. Later I decided to create the design table for Part 1 that included those variable dimensions, thus a new configuration was added. Now if I change Part1 configuration in the assembly, Part 2 won't update. Looks like equation always takes that original dimension in Part1 default configuration. Any comments? Thank you all.
