some times when I try to select some polygons it select the polygons on the other face of a cylinder for example and some times it do not
regardless the option Ignore backfacing , now I need to select the polygons on both sides how can I do that please
Select the polygons that you want on the front face, hit the space bar to lock your selection temporarily, go into the view rotate mode (it's the button down at the bottom right of the interface - theres' also a shortcut for it which I don't at the moment remember), rotate the view to where you can see the backside polygons you want. Hit the spacebar to unlock the selection. Hold down the Control key and select the additional polygons you want. That should do it!
