Blender Select Random Face But Not Sides I am making an abstract sphere in blender and am having trouble with the random select feature. Basically I want to only select outer faces and not the "sides" as shown in this picture.



Does anyone know of a way that I can use the random select, but then ignore side faces of my model? (Without having to go through and painstakingly deselect them all by hand)
You can do this in two steps:


Select one of the triangular faces, press ShiftG (Select Similar) and choose Polygon Sides. Now all triangular faces should be selected.
Press space, type in Select Random and hit Enter. Now here comes the trick: You can switch from Select to Deselect mode in the Tool Shelf on the left hand side of the 3D viewport:



If the Tool Shelf is not shown press T while your cursor is in the 3D Viewport.
