Hi,
Thanks a lot Michal for the help... I know at times simplest things also become difficult to do and you just made my day and saved my time...
Also one more thing, from top viewport I am making a C shaped spline and giving it a min thickness and the extruding it to half an inch. Here i want to distribute some flowers on just the front faces ie : on the 3 front faces, but when I do so it distributes on just the front face (viewing from front view) but both the side faces remains blank they don't get distributed with the flowers, so I made 3 different polygon and used 3 different forest objects to distribute flowers, I think this is a wrong approach and it can be achieved by one forest object and 3 sided polygon, I tried to follow the post that showed how to distribute objects on steps but I failed, so any tips and method that I need to follow...
