In this lesson video, we are going to discuss about three basic modeling features inside vendor. But before we do that, there are two things that you need to understand in terms of 3d modeling. First, to access the modeling features, you need to be in edit mode, not the object mode. Second, you need to remember that each of the modeling features are tied to a certain type of mesh element. What I mean by this is that a 3d modeling feature that exists in the face mode, for example, may not exist if you are currently in the H mode or Vertex mode and vice versa. So this is something you need to be aware of.

Okay, first, let's discuss about insect insect only works in the face mode. Okay, so let's select this monkey head model here. Go to Edit mode by pressing tab and then make sure we are in the face mode, not age or Vertex mode. Then Tuesday insert tool in here. While this tool is active, if we click and release on a face Blender will select that face. But if you click and drag in the viewport, it doesn't have to be right on top of the face, you can click and drag even on empty space like this.

Notice when you do that you are doing the insert operation. As you can see, essentially insert will create new faces by shrinking the selected face. After doing insert, you can still change the last insert operation details by going to this panel down here or by pressing f9 there are many things we can control in here. But for now, let's just focus on this thickness value here. As you can see, we can precisely control how thick the inset operation is by using the slider. Or if you need more precision, you can click on it and type in a value that you like.

Now if we click on this face, hold SHIFT and click again on several other faces like this and do a click drag again we can see that we can actually perform inset on a group of faces Okay. Next is the extra operation which you can access via this tool here. Now although we can use extra in vertex, age or face mode, do I extra behaves is different for each of the mesh element types. For now, we will be focusing only on face extra operation, not vertex extrusion or H extrusion. So just make sure we are in the face mode now, to extrude a face first, we can select a face by clicking on it, then you can click directly on this plus icon to extrude that face, we can drag this inward or outward depending on your need. So basically extra will create New Faces by pushing or pulling the selected face from the initial surface.

Notice that when we drag this plus sign again, a new extrusion will be created, and the direction of it is always facing the normal direction. Now if you don't know what normal direction means, basically the term normal direction in computer graphics is the direction perpendicular to the face plane. We can click to select a face, then hold SHIFT and click again on surfer or more to select multiple faces. This way we can x through several phases at once. Now to x through we can also do click and drag anywhere on the viewport, but this method will produce a free form extrusions. Meaning the direction will just follow where our mouse cursor is going.

It does not to follow the normal direction anymore. And as with insert after doing extra We can press f9 or access this panel down here to control the less extrude operation. The last modeling technique we are going to cover in this lesson video is bevel. There are actually two types of bevels vertex bevel and H bevel. In this video, we are going to focus only on the age level. So let's select the age mode.

To bevel an age we can activate the bevel tool, which is this button here. Now the same principle applies, we can click to select an age or hold shift and then click again to select multiple ages. To bevel these ages, we can click drag anywhere in the viewport. So basically, bevel operation will add new faces by splitting the selected age or ages. If we open the less operation panel down here, we can see there are many parameters that we can tweak. We can control the width the amount of segments And we can also play around with the profile value.

Setting this value down towards zero will make the bevel area becomes recessed or concave
