Hi, I have a large number of projects done in Altium . These projects are using a custom database file where the logic is similar to EASYEDA -PRO operation. A record describes symbol,footprint,3d model . I proceed to import but since many parts (eg. resistors ) have the same schematic symbol (i use RES) i end up with parts in EASYEDA schematic that have different name but same device  type. After import in EASYEEDA devices are associated to schematic symbol .So this means that all different resistors in my database are all RES devices having different name .Footprints are not imported  and also 3d models also .These are shown as extra fields but i can't use them My first thought was to change devices  in group change mode .Eg.All existing 1K 0603 resistors changed with one action from RES to 1K_0603. Doing that in edit device changed all resistors no matter value in my schematic to1K_0603 device . So working with DDB parts is not possible. At least can i select common devices and group change ? Is there easy way to do that ?
