Make sure when you created the property tab, you have selected custom tab.
Bernd Olde Veldhuis:
As far as I know this only works when Custom properties are filled in and not Configuration specific properties
You can also linked the configuration properties in same way as custom properties to show on drawings.
You are not doing anything wrong. The configuration specific tab is still the custom properties the only difference is that the configuration specific information will take preference over the Custom Properties vaule. e.g. if you have a Description under the Custom properties tab it will be overwrite on the drawing by the Description in Configuration Specific. I hope this make sense.
