The catharsis of deleting all the old dimensions I don't need and giving sequential names to those that remain is completely undermined when I create a new dimension.
Drives me insane and makes it impossible to find anything. And that's just in my very simple parts. I can't imagine what people with complex assemblies do.
I suppose if you delete some dimensions but their sequential number may not at the end. For example, there are d0, d1, d2, d3, d4 and d5, you only delete d2 and d3. If you add a new dimension, you want to have d2(purge the deleted number) or d6?
Use Undo will purge the sequential number.
Also, you can rename the dimension name(dx) in FX table and make them more sensitive to you.
