Use tracing feature of DrawHome to convert an existing floorplan into an interactive 3D model
In the sidebar menu, click Upload menu and select 2D floorplan (You will need to login).
Once a floorplan is uploaded, it is placed in the project.
Resize it to the correct dimensions.
Switch to Draw mode and start tracing on top of the floorplan. Once complete, switch to 3D mode to see the finished project.
Pro tip: Move the floorplan image away from the project to clear the "X-ray" effect of walls that are on top of a floorplan.
