In only 14 lines of python code, you manage to display a line in a 3D window. I think it's not bad! What do you mean exactly with 'simpler'? Do you mean 'less lines'? Whatever the alternative solution could be, you will always have to : * import python modules/packages, * define two points (or a point and a direction), * create the line from these two points, * send the line to the renderer. You can use for instance high level wrappers to generate the edges from the line: from OCC.Display.SimpleGui import * display, start_display, add_menu, add_function_to_menu = init_display() from OCC.gp import gp_Pnt, gp_Dir from OCC.Geom import Geom_Line from OCC.Utils.Construct import make_edge p1 = gp_Pnt(0,0,0) line_dir = gp_Dir(1,1,0) my_line = Geom_Line(p1, line_dir).Lin() display.DisplayShape(make_edge(my_line)) start_display() This sample is 11 lines, I would not say it's simpler but smaller.
