House part editorHouse parts defines smaller images you can use to build up your houses. The first step involves in uploading an image to the engine. The image can contain a single house part or multiple one as a set. One the image is within the engine, you must give it a name and define the area of interest. You can do so either by dragging the mouse over the preview or by writing the coordinate manually for example for fine tuning.
In case you had multiple house part on a single image, simply clone the part, give it a name and redefine the area of interest.
