Building a Polygon Arch
4. Right, now you can see that you have made an "Arch" poly, without using a boolean. Pretty cool hey, anyways, now we need to give it some width. Before we do that now would be a good time to fine-tune the vertex points of your arch if you feel like you need to and then you should save the scene, you never know what could happen. Once that is all done, switch to your perspective view and select your poly and then select your polygons face and extrude it using the Extrude Face command in the Edit Polygons menu. Extrude the face about 0.6 or so in the Z axis. Once that is done delete it's history once again.
5. Cool, we are nearly done. Next step is to add a bit of detail. Select your poly and go into Edge component mode and select the first edge at the bottom, then go to the Select Contiguous Edges under your Edit polygons selection menu. Once you have executed that command it should select all of the edges on the front part of your arc. Now that all of those edges are selected extrude the edges by going to your Extrude Edge command in the Edit polys menu. Just remember to not deselect any edges before the extrude. Once the extrude has been executed, the transform handles should be at the bottom, once again before deselecting anything hit R on your keyboard to bring up the Scale handles, once that has been done the handles should move to the center of your poly with the newly extruded edges still selected. Next step is to switch to your Side View, again without deselecting anything. Now that you are in your side view select your little blue( Z axis) scale handle and scale it out to your left, thats when you should see the newly created polys form another "outer arc". Once that is done, you need to deselect the bottom two edges without deselecting the rest of the edges, you do that by holding down your Ctrl key and dragging a selection box over the two bottom edges. Once the bottom two edges are deselected scale the remaining edges down by selecting the little green( Y axis) scale handle and moving your mouse down. Once you have done that you should see all of those extruded edges that we made earlier form the outer arch. Now that we have the outer arch done we can now deselect all the edges and return to object mode and delete it's history again. :)
