Miscellaneous
· Positioning surfaces: Surfaces can only be repositioned in the plane in which they were created.
· Representation in 2D views: the representation of a surface in 2D views, i.e. filling or hatching, is as always dependant on the building material used and can be modified by clicking on the setting for material, located above the drawing.
· Relationship to other objects: If a surface is created on a construction element, for example a wall, then the surface automatically reacts to changes in the position of the element. If the wall is repositioned, the surface moves with it, but not vice versa. However, if the wall is deleted the surface is retained, since it could be that the element was only created temporarily in order to define the plane of the surface.
· The scale of the texture on a surface can be changed in the dialog using the 
button.
· Other materials and textures from the catalog can be allocated to a surface in a 3D view in the usual way using drag and drop.
· Modifying surface area: Selected surfaces in 2D views show ‘grips’, with which the position and dimensions of the surface area can be changed, in the same way as with 2D elements.
