Hi Petr, re: Lock - actually what happens in this case is the rebuild command locks the input objects, and if that object is then deleted with a call to moi.geometryDatabase.removeObjects() it will get recorded on the undo stack with that locked property set.

So this can be fixed by just unlocking the objects before they are deleted in RebuildCurve.js .


For the next v2 release I've also added some methods on factories so that it is easier to retrieve the objects that were generated and inserted into the geometry database with a regular factory update() call.
