I have been asked to add stormCad data to my openroads model .I created a new file and under subsurface utility there is a project/import/import *.stsw tab. When I do that it goes thru the process of creating the utility model but when it finishes I get the message "import into default failed". I have no experience with stormCad so looking for some explanation of what is missing that is causing the import to fail or a link that has more information (or both!).
Thanks for your help,
Brian
