I added a new Via in central library using the library tool xDM Library Tools VX.1.1. I close the library and open again to verify that new Via exists. Latter in PCB Xpedition I update the library ECO => Update Cells and Padstacks but in Setup => Constraint Manager => Net Classes => Via assignment but I do not see the new Via. I update again the Cells and Padstacks under ECO but still new Via does not appear in Via assignment. Do I need to update library in some other way in the existing project ?
