Rooflights - Replace with a different Symbol...?

[shorter]

How do you replace en-masse one rooflight with another?

 

It is a symbol after all and one should be able to select out all rooflight symbols placed in roofs or roof faces, and replace with a different symbol but it does not even look like you can replace a single rooflight.

 

Custom Selection and Modification 'see' the symbol but cannot act upon it.

 

Do you really have to delete them and start again?

 

What am I missing?

 

(FYI, These are called 'skylights' in Vectorworks.)

You can delete the symbol in the RM then choose to replace it with the new symbol. This will replace the symbols inserted in the roof.

That's a bit destructive if you are still using the symbols elsewhere, but yes, that is one option albeit slightly perverse.

Agree completely: rooflights are crazily lacking in functionality
