So I'm modeling a window for a scene and used a half circle and the boolean modifier to create a half circle in a mesh.
On the right side you see the cuts I made using the knive tool to create quats and tri's.
On the left side you see just 1 face that I created by selecting all the verts of creating a face.
Is there any partical reason why I should with left or right? As far I can tell left just add's more verts to my scene.
