    Testing valid shape Reply

    I have a script that is doing layer booleans, modifiy, deleting shapes. I need a way to test if the variable has a valid shape. I am getting the message in the ciw  dbGetq: object is a purged/freed object - db:0x2ab1132fa2.

    I know the shape it is specifying has been deleted. 

    Is there clean way of testing if a shape/variable is valid in a boolean statement or a script that returns a boolean?

     Thanks

     I have tried some various uses of getWarn, errset, ~>isShape, symeval, and maybe some others.

    Have you tried this?

    dbIsId( 
d_id 
) 
=> t / nil
 
Returns t if the argument is a valid database object ID, otherwise,
it returns nil.
