Identify door reveal depth of custom objects

[kency]

We have a set of custom doors which was in .rfa format. We have imported those using the Import RFA as GDL Object option under Libraries and Objects. But after placing the door on the wall we could see that the door appears to be not inside the wall. This offset is different for different doors. Does anyone know of any way we will be able to identify this difference in the reveal depth value so that we can read the library object's property and set the correct reveal depth for the door?
