Thanks guys - ZORO2 is just the ticket!! Kind Regards Syd

Hello remus Thank you for your reply. I already have Layer Manager v6 installed, but there is no functionality for this feature. I am still searching. The workaround is to open an additional SU window and a coy of the file in question, rename a suitable layer to make a replica copy of, and copy and paste an object on that layer into the target file in the other current SU window. This is surely more time consuming, hence the request. Kind Regards Syd

Thanks guys - I've added the code: { Sketchup.active_model.selection.clear } to the existing ContextMenuMenus.rb file TIG supplied Kind Regards Syd

Copy with Move+Ctrl has functions above the Edit>Copy etc You can Copy with a base point by picking a start using inferencing and then typing in an offset, using axis locking (shift) etc etc. You can also multi-copy as an array using NNx or NN/ after making the first copy to set the number made after/between. Similarly Rotate+Ctrl make copies about a centre and again NNx or NN/ sets the number of copies after/between

Thanks TIG Syd
