Hey, welcome to Vue! Isn't it great? I've been using it over two years, and I'm still excited about it! grin DEMs are usable in Vue. You should see the option available in the terrain editor for importing them. There are folks using 'em (I'm not one of them who does), so someone who does will probably spot your message soon and respond. Perhaps they'll have tips for the import. Otherwise, don't hesitate to contact E-on's tech support. It might take a day for them to get back to you, but they are very good about helping users work out difficulties. :)
