Family Table Update Order

[looslib]

Is there a defined logic order for updating family table instances from the values in the table?

I have a hydraulic fitting that will successfully regenerate for 7 of the 8 instances. When I changed the generic values to be close to the instance that failed, I now get 5 of the 8 to regenerate.

The whole shape, except the hex cut, is in a single revolved sketch, not the way I would have created it, but that is what I was given to work with. I don't really want to change this since I don't want the existing assemblies to fail because of features that are new.

What accuracy are you using - relative or absolute, it could be that the instances are using the generic's accuracy and this is why you are getting different results by changing the generic. You might be able to solve the problem by using absolute accuracy, especially if there are relatively small entities in the sketch or cut.

Eevryone who has replied has said to try changing the accuracy. I tried a bunch of values and non made any difference.
I then went back and changed some angles on the part and am now back to just the one instance failing.
Someone else took the same starting generic and added the same new instances and all of them update. I have compared values and mine just won't create.

Why not open up the failed instance and see from the Info what feature is actually failing.

Hi Looslib

I have had to swap columns in the family table, some features may need regen before others, like a cut before a rad. Or a feature is called up but the references are not.

Hi Ben,
Sounds like a problem somewhere in the sketch. When I run into the same problem it's usually because the dimension change causes a zero-length line or a constrained arc to fold over on itself. Sounds like the most likely scenario since you've been given a 'feature-efficient' model.

Sometimes just reworking the dimensions/constraints in the sketch will do, other times I have to use Edit->Replace in sketcher, and work line by line to make sure my assemblies don't fall apart.
