I need a macro to autosize all planes in a part or assembly file.

I found this macro​ but it doesn't work for me.

Because my planes are hidden and a hidden plane can't be autosized. (If I right click a hidden plane, there is no autosize command)

And obviously I don't want to show all hidden planes manually before running this macro.

I tried to add swFeat.Visible=True to the macro, but I received an error that swFeat.visible is read only and I can't assign a value to it.

How can I make planes visible in this macro to be able to autosize them?

Or if not possible, is there any macro for autosizing hidden planes?

Thanks for any kind of advice.
