Hello there...Is anybody can help me about flag pole detail? I need flag pole detail for my project but can't find any in libraries. Please help

What kind of details are you looking for?I can't imagine there is that much effort involved to draw a detail or two for a flagpole.  There is the flagpole itself and then the foundation it sits in.  Now unless the flagpole is of the type that can be fully lowered to the ground I don't see where there is much more that you need.
