A2plus giving an unknown error

[AshAsh]

Hi Guys,

I have been working on A2plus and it is giving out an error about inconsistent Constraint, I have checked out and nothing seems to be the faulty
stuff, but I am still getting this error.

Cheers.

Hi,
A2plus complains about an insolvable constraint system. In this cases, you have to know which last changes you did to the assembly. There are some main reasons why this happens:

(1) you have edited a constraint ( perhaps flip direction e.g.) If this error occures, just edit the constraint again to it's state before change and think about, why the last change could conflict with other, existing constraints.

(2) you have added a new constraint, which perhaps is incompatible to existing constraints. Just delete the new constraint and try another one.

(3) you have updated your assembly with a fresh edited part. This is very dangerous due to FC's topological naming issue and constraints references can jump to false and not wished geometry. Delete all constraints of the edited part and define new constraints for this.
(This problems can be reduced if the preference option "use experimental topological naming..." is active from the very first beginning of an assembly)

In generally, save your functional assembly very often, so that you can always go back to a viable state.
