In this article, only uncoloured patterns are considered and the interlace patterns are disregarded. By repeating these basic elements, it is possible to construct patterns having various symmetry groups. The combination and the overlap between these basic elements generate other basic elements. The corresponding commands are called Inset ( Ctrl+() and Outset ( Ctrl+) ). by displacing it perpendicular to the path in each point.

The set of patterns are generated from n-fold rosettes, considered as the basic motif, by the Hasba method. Inkscape can expand and contract shapes not only by scaling, but also by offsetting an objects path, i.e. In this work, it is shown that it is possible to obtain the 17 plane symmetry groups by using a master craftsmen's method called Hasba. Go to Edit > Clone > Create Tiled Clones 5. Drag the + sign, currently in the middle of the shape to the center point of the circle that you would like to rotate the shape around. Groups p4 mm and c2 mm are predominant, p6 mm and p2 mm are less frequent, while p4 gm is rare. Click on the shape, and then click on it again to bring up the ‘rotational handles’ 3. Studies and analyses made on nearly a thousand Moroccan patterns constructed on wood and belonging to different periods between the 14th and 19th centuries show that, despite their great diversity, only five plane groups are present. Many works report the classification and analysis of geometric patterns, particularly those found in the Alhambra, Spain, but few authors have been interested in Moroccan motifs, especially those made on wood.
