Can not delete objects outside of AOI

If you are trying to use the function for deleting objects outside of the AOI, but get an error about not being able to delete read only objects, then follow this procedure:

• Start the function to "Delete objects outside AOI" from the "Modelling" ribbon

• Try to run it once, this will delete the objects that are outside AOI and are reserved right now

• Start the function again and note the first object in the list

• Exit the dialog

• In Quadri for Windows Explorer, right the worksets cloud symbol and select "Search for object ID"

• Enter the number of the first object you had in the list and press "Select"

• Look in the "Properties" window to see which task this object belongs to

• Reserve that task

• Run "Delete objects outside AOI" again, this should delete at least the first item that was on the list

• Repeat this operation until "Delete objects outside AOI" can not find any more such objects.
