Well, that does the trick! Thank you gkokovidis, this is much appreciated!

Here's another quick one althought it's not as important: you can see that the bike and scene are thick and not very nice when the plot is not enlarged a little. I usually do so manually by clicking on the plotting area and moving a corner further away. Is there an option such as width= and height= that would help display the graph with the proper size without requiring any action from the user?

Thanks again!

Also, here is the whole file in case somebody would like to take a look. The comments are in french so it may be hard for you guys to see what is what but i've added big red comments (can't miss them) to show you the problematic spots. Again, only the bench is the problem and it's driving me crazy. I don't have much time left before i have to submit it. Thanks again for all the help.

Thanks gkokvidis! Adding brackets worked for the sun (disk) beeing in front of the background polygon. However, i still can't figure out the last piece of the puzzle: the bench. Here's a small example in which i cannot manage to bring the black ellipse in front of the half-circle. Go figure.

@hirnyk Sure, i will later today. However, the code is very big and i doubt you need all of it for this particular issue. I thought the code of the only three problematic objects and the final calling sequence would be enough, i apologize for my "stupidity".

I probably could reformulate my question this way: If you want to display a solid polygon (rectangle) and a solid disk in a Maple plot, how would you do it to have the disk appear over the rectangle, instead of hidden behind?

Anyway, what would be the best way to post this? Just zip the .mw file and give you the link? These boards seem pretty advance in options, is there a better way?

...and thanks for helping!
