[quote="Dave R"]Paul, this isn't a bug with SketchUp 2013 so I moved it into SketchUp Discussions. Thanks for that Dave. Just back from dodging raindrops in the New Forest. I will sort this out, many thanks for your response. Best regards. Paul

Thanks Thom, I have done, but its a slow process. They are pretty good on the IES side but I am having trouble getting registered on their system so I can leave posts. You'd think by having 100+ licences of the software at the college they would give a bit of lattitude. Still, my clumsy little workaround suffices for the moment. Regards Paul
