Problem with Design Table

I'm modelling (in SldWks 2003 sp3.1) a range of cast gearbox housings, of
similar form but spanning a range of sizes.

The different sized models are driven by a design table. At the end of the
process I am tweaking a few sizes to reflect reality, as measured from
evolved actual castings, rather than the 2D drawings whose updates have been
sporadic.
In order to easily tweak those sizes, I turned on the "Allow model edits to
update the design table" switch.

Shortly thereafter, my model went pear shaped (almost literally). The
problem sketch was *not* one I had fiddled with.

The "problem" sketch in configuration 3 has spontaneously reset all its
dimensions to match those of the same sketch in configuration 4

My best guess is that the substitution was triggered by a dangling relation
problem in configuration 4 causing that sketch to be unable to solve, and
"locking in" the config 4 dimensions, so that when I switch to config 3 the
"locked in" dimensions for that sketch are seen as having changed for config
3, and are accordingly propagated to the design table, over-writing the
correct ones.

Has anyone struck a similar situation? Any insights?

I know what you mean (that is a trap) but in this case I hadn't changed
those dimensions in ANY configuration. As I mentioned, I hadn't fiddled with
that sketch at all.

The dimensions in the sketch for the various configurations had not been
touched since they were created (not from the spinbox input, but by typing
into the design table worksheet). All the dimensions in that sketch, in
config three, changed spontaneously to match those in config four.

 

Not sure... but when you changed the dim.. was the 'This configuration only'
displayed in the dimension dialog? This one has caught me more than once..
