 So you just need to extrude faces, not a problem. Extrude edge faces lets you left click drag a new face in whatever direction you click. Normally it will smooth drag out wherever your mouse is, but you can set it to snap every 15 degrees like this, or you can have a custom amount that you want it to rotate by. For example if it's set to 45 degrees you can pick that here, and it'll snap at every 45. Edge loop complete will extrude an entire loop, edge loop partial will extrude from every point that is connected to four edges. So down here it will pivot the whole loop, but if we click up here these two points only have three edges connected, so the loop will stop at these points. Poly loop island will extrude every point that belongs to the edge loop you clicked on that is also the same color. So if we click on blue you can see that all the blue edges will be extruding, but if we click on green now only the green edges will be extruded. And when we set to poly loop you will see dependent on where you click your mouse a pointer will glow up down left or right. If you left click it will extrude a new edge loop that is parallel to the direction that the arrow was glowing. So here you can see that it's pointing to the left so the extrusion will be horizontal. But if the arrow was pointing up then the extrusion will be vertical. Hope that helps and as always we have a fantastic day and I'll see you around.
