The shared ShapeDiver system is still running Rhino 6 at the moment. The Import Geometry component relies on Rhino 7 functionalities and therefore cannot be used on this system. Designer and Business accounts already have access to the Rhino 7 system, while the shared system will be switched to Rhino 7 later this year.
We have still not switched the shared system to Rhino 7 and therefore svg import is not possible there. This will not happen until later in the year. Designer and Business accounts already have the option to use Rhino 7 on request.
