The reference that you point to above notes that the CYLINDER primitive takes the arguments: CYLINDER, x1, y1, z1, x2, y2, z2, radius, red1, green1, blue1, red2, green2, blue2, If you want to change the color of the cell, then you should change the two triplets of values within the square brackets after the radius. The line in my script cell = cell + vert_000 + vert_100 + [radius] + [0,0,0] + [1,0,0] draws a cylinder coloured from black to red, while cell = cell + vert_001 + vert_011 + [radius] + [0,0,1] + [0,1,1] draws a cylinder coloured from blue to cyan. As Jason answered, .append() and .extend() are python functions that apply to lists. .append adds one element to a list, while .extend adds each of the elements from its argument, which is itself an iterable object. And I can't speak for others here, but since I read the e-mail list, there is no need to CC: any e-mails for the list to my own address. Cheers, Rob -- Robert L.
