Hi!
 
I've downloaded the Trial-Version of ImageModeler and after setting all the markers I wanted to definde the worldspace. So I dragged the (yellow) origin over a locater of my choice so that the mouse-icon turned into a magnet-symbol. But instead of snapping on the place I pointed, the yellow disc jumped back to its previous position. - Why? (While the Step-By-Step tutorial everything went quiet well...)
 
And finally I don't understand (also after reading the online-help) all the Modeling-symbols and their functions. Does anybody has a further explanation for me or a relevant URL?
 
Thank you and Best Regards,
Daniel
