This section introduces you to some basic concepts in modeling. Polygonal modeling or box modeling is a system of building a model through working on it’s components… the vertice, edge and polygonal face. If you don’t know what the components of a mesh model are, go here.
Components of a mesh
A note about edges…
- Edges are the lines that connect the vertices.
- An edge-ring is made of the edges that surround the selected mesh.
- An edge loop is the connected loop that holds that edge-rings together,
You can see from these images that box modeling gives you literally unlimited amount of control over the final outcome of the model. In fact, the amount of tools available for box modeling are mind boggling. You can manipulate the 3 components in many different ways by slicking, cutting, stitching, dividing, dissolving…
For instance, here’s how you would build a house through box modeling .
- Create a cube
- Saw it in half to insert a new edge
- You will now see a new edge loop in the cube.
- Pick the top edge and lift it upwards. Voila, a roof!
There are loads of tools in Gsculpt that allow you to take apart or build meshes. I will leave you to the joys of discovering what each one does. This page will only introduce you to 3 basic actions, which will comprise of almost 80% of your base mesh building.

There are many ways to extrude a face, but the logic is the same. When you extrude a ‘block’, 5 new faces are formed. (4 on the sides, and one on top.) You will use this technique to build and add dimension to your object.
Insetting a face is like projecting a window onto a wall. This is useful when you want to create more detail on a face without extruding it outwards.
Beveling is usually used to smoothen a hard edge. When you bevel an edge, a new face is formed between the two previous faces. This is a useful tool because real life has very few hard edges, and you will find yourself beveling almost anything that you build.
These three techniques were used to build a marker in this tutorial. Go here to see it.
When used alongside the tools that you read about in basics (scale, move, rotate) these techniques are very useful.
