+This extension allow you to draw a isometric grid with inkscape
+There is some options including subdivision, subsubdivions and custom line width
+All elements are grouped with similar elements
+These grid are used for isometric view in mechanical drawing or piping schematic
+!!! Y Divisions can't be smaller than half the X Divions
