extrude along this path

Hello I have to make an animation with this shape, but i cant find out any tutorial to explain me the method to achieve the result I'm looking for. I would like to extrude and animate a square shaped polygon that follows the yellow arrow path so that it builds up the entire shape in red.

Thank you very much for your time.

  • It is difficult to understand what you would like to accomplish. Could you draw some sketches of the animation? – Dontwalk Dec 07 '17 at 17:31
  • Use curves and animate the bevel's factor start and end: https://blender.stackexchange.com/questions/34377/how-can-i-create-light-streaks-in-cycles/34383#34383 –  Dec 07 '17 at 17:53

  • make individual curves, one for each letter and animate those sequentially. –  Dec 07 '17 at 19:01

  • thank you cegaton for your help , anyway i still cant achieve what i need with the curve and bevel , indeed its very usefull to animate a scriptural writing but i really need to keep the shape of the logo wich is square basicaly. i am very new to blender i must precise i may have not yet memorize all the functions , but i thought that it should have a way to build up this logo keeping it sharp ; – halim benkhennouf Dec 07 '17 at 22:22
