A quick look at the Blender jargon
A brief Dictionary/Glossary of Blender Terms and concepts in simple, understandable English
2D in Blender means an object with two dimensions – width and breadth – but no height. It is a drawing on a flat plane. Blender has a 2D tool called Grease Pencil, which allows you to draw in 2 dimensions. For more info, here is a Wikipedia article.
3D in blender means an object with three dimensions – width, height and breadth. An orthogonal view in a 3D viewport is a 3D view of a 3D object with no parallax correction for distance, so it looks odd. Don’t confuse this with an Orthogonal Viewport which only shows two dimensions at a time.
A Bevel is a set of one or more flat faces joining two other faces that lie at an angle. This article explains it in much more detail.
A Destructive operation in Blender is an action that cannot be modified later. See here for more information. Contrast this with non-destructive behaviour.
- When a face is extruded, the face and its bounding edges are moved and new faces are created which stretch from the new edges to the original edges on all sides. The direction of the extrusion is usually perpendicular to the selected face (the direction of the Normal).
- When an edge is extruded, a copy of the edge moves and a face is created connecting that edge to the original edge.
- When a vertex is extruded, a copy of the vertex moves and edge is created between the new vertex and the original vertex.
The LoopCut tool creates one or more edges by splitting a series of quad faces. When the LoopCut encounters an Ngon or a Tri instead of a quad, it stops the cut, only going as far as the line of unbroken quads.
An Ngon is a face on an object with more than four sides. A three-sided face is called a Tri; a four-sided face is called a Quad. For more info, click here
A Non-Destructive operation in Blender is an action that can be modified at a later stage by adjusting a parameter. See here for more information. Contrast this with Destructive behaviour.
An Orthogonal view is a view of a 3D object with no parallax correction. An Orthogonal viewport is a viewport that shows a view of an object perpendicular to one axis, thereby demonstrating the object in a non-distorted two-dimensional view. See here for more info on orthogonal views of objects
A Perspective view is a view of a 3D object with parallax correction. It shows how an object would appear to the eye depending on how far away the eye was located. See this article for more info.
