If Aprons are created in a separate xml file by the user, the current import xml procedure ignores it. I posted this on 11th Feb 2019 under the headingCan you explain a bit more please
Import XML seems to do nothing . You said you had put if on the list at that time, hence why I said it was a memory jog. I have created a program to import KML from Google Earth and generate BGL files with the aprons to a high degree of accuracy. However, as I can't import them into ADE, they remain independent entities instead of being part of the ADE Data. The thread from 11th Feb provides both the project and the XML generated.
