How to select last entity selected?

[renderiza]

Hi,

When I select multiple entities how can I use the last selected to use on code or maybe the first one.

These are not doing it for me;

@@sel = Sketchup.active_model.selection[0] ;
or
@@sel = Sketchup.active_model.selection.first ;

Thanks and if I reply to myself again don't think I am crazy! XD

Not sure if the model.selection collection relates in any way to the order entities where selected.

You might want to use a SelectionObserver...

Btw, model.selection.first won't work - you'd have to convert it to an array first: model.selection.to_a.first

Gotcha Thom...

The API defines a first() instance method for Sketchup::Selection

so:
Sketchup.active_model.selection.respond_to?(:first) %(#008000)[> true]

Ah! Oh the joy of API inconsistency! I actually tested selection.last - and just assumed...

I have tried but seems I can't get it to work or understand correctly. Is there a sample code that can better illustrate this.

Thanks!
