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?
