Hi Justin,
We have a restricted viewpoint in our 3D viewer in floorplanner. In our other platform, Roomstyler which is more focussed on interior design of a room than on planning a complete floor. In Roomstyler you can place you viewpoint anywhere you want. Soon we will make it available for free users to import your floorplan basics into roomstyler. We currently have this option available for our paid users as a beta functionality.
