Newbie, evaluating the free trial:
When I place components from libraries I created myself (or imported from Eagle libraries and edited in some way), pin designators and -names are always shown in the schematic. While that is ok for an IC, it is a mayor nuisance in small passives like resistors or caps. On all levels (accessing pin properties from the schematic, or in the library editor) "display name" and "Designator" visible checkboxes are off.
Components from the Altium delivered "Miscellaneous Devices" library don't show this behaviour, there I can turn on and off the designators / names in the pin properties dialogue invoked from the schematic.
It looks like there is a global setting on the library or library pack level that overrides the individual settings - but within an hour trying I was unable to find it. Any hint is welcome.
