Boolean operations are a method of combining or subtracting solid objects from each other to create a new form. Boolean operations in Blender only work on two Mesh type objects, preferably ones that are solid, or closed, with a well defined interior and exterior surface. If more than two mesh objects are selected only the active and previously selected object are used as operands.

The Bevel Modifier adds the ability to bevel the edges of mesh that the Bevel Modifier is applied to, allowing control of how and where the bevel is applied to the mesh.

A Modifier is defined as the application of a "process or algorithm" upon Objects. They can be applied interactively and non-destructively in just about any order the users chooses. This kind of functionality is often referred to as a "modifier stack" and is found in several other 3D applications.

Retopo (remake topology) is a tool for remaking the topology of a mesh. It’s the opposite of the sculpting tools: instead of reshaping the model but leaving the topology the same, it reforms the topology, but maintains the same shape as the original model. You will not change the geometry of the original mesh in any way, you will be creating a new mesh that is projected upon an existing mesh. There are three ways to use retopo. Let's detail them!

Sculpt Mode is similar to Edit Mode in that it is used to alter the shape of a model, but Sculpt Mode uses a very different workflow: instead of dealing with individual elements (vertices, edges, and faces), an area of the model is altered using a brush. In other words, instead of selecting a group of vertices, Sculpt Mode automatically selects vertices based on where the brush is, and modifies them accordingly.

Multires stands for 'multiple resolution mesh'. Multires allows you to edit the mesh at both high and low levels of complexity. Changes you make at one level of resolution propagate to all other levels.

A Subdivision Surface is a method of subdividing the faces of a mesh to give a smooth appearance, to enable modelling of complex smooth surfaces with simple, low-vertex meshes.

The Weight Paint Mode is used to create and modify Vertex Groups. A vertex may not only be a member of one or more Vertex Groups, but also may have a certain weight in each group. The weight symbolizes its influence on the result.

A mesh is a set of connected Vertices, sometimes thousands of vertices for the more complex objects. Blender allows you to group these vertices for several main reasons. let's talk about them.

Used in conjunction with Grab, Extrusion, Scale or Rotation modes, this tools allows you to snap objects (in Object mode) or vertices/edges/faces (in Edit mode) to a target vertex/edge/face.
