I need to draw some discontinuous lines onto a circle (360°) from center of circle to diameter ( a little as sun ) lines have a thickness = l and lenght = L theta is an input , and determines number of lines on 360° discontinuous lines (= lines with space ) are an random function , not space at same place may be space would be an % of lenght of line do you have an idea to do this in ruby ? or just for beginning , to create some random lines with space thanks -

Hi, try this: `ly = RBA::CellView::active.layout li = ly.layer(1, 0) # or the layer you want to draw on n = 100 # number of rays rad = 1000 # radius database units width = 10 # width of rays in database units n.times do |i| a = i.to_f * Math::PI * 2.0 / n x1 = 0 y1 = 0 x2 = rad * Math.cos(a) y2 = rad * Math.sin(a) path = RBA::Path::new([ RBA::Point::new(x1, y1), RBA::Point::new(x2, y2) ], width) ly.top_cell.shapes(li).insert(path) end` Matthias -

Hi mathias thanks , but the real pb for me is to do same thing with discontinuous lines in place of radius lines. or to had , in a second layer some random space ( or blank ) on previous lines to do discontinuous lines after boolean operation. and very important , blank ( or space ) on lines will be random from radius line. after , in my mind ; i will have choice to select number of blank ( or space or discontinuous area), for example 1 to 5 blank by radius line , and so , a % of lenght of radius line. -
