Hi,
I'm working with a builder on a new house. He's doing the design in SoftPlan and he sent me the .spp file and associated .spd files. I downloaded the trail version of SoftPlan and opened the .spp. However, when I try to display one of the drawings (e.g. Model -> Upper Level) I get "Error 545: The drawing cannot open because it is missing account validation information."
He warned me that he's using an old version of SoftPlan and that it might cause a problem, but surely new versions of SP are able to work with files created by old versions?
How can I open these drawings. My ultimate goal is to export the house in a format to 3D print it (and, hopefully, print the house and roof separately).
Thank you for any help you can offer.
