This tutorial is about creating a set of mechanical stairs (escalator), like the ones in shopping centres, undergrounds, and so on.

Create a simple box and add an arm to it to make it a jack-in-the-box.

Here are some solutions for getting around your SubD model if navigation and editing becomes slow. Open the Hypergraph. Options > Display > Shape Nodes. Select the shape node for your SubD model , and "show up-and-downstream connections". Right-mouse over your SubD model in the viewport and go to Poly Proxy mode. In the Hypergraph, you should see the downstream connections change to a historyshape node (the poly proxy) and a bunch of blindData nodes. Delete the blindData nodes. If you move vertices on your model, you should already see a slight increase in speed. Create two layers. Select and assign the the poly proxy (historyShape) and the subd shape node to seperate layers. Hide the layer with the Subd shape node Middle mouse drag the Poly Proxy (historyShape) node over the shading group (at the right end of the network in the hypergraph) to give it a material, so it is shaded in the viewport. Now move some vertices on your poly proxy and you should have full interactivity! You can hide and show both layers whenever you want. (Note that the greatest performance increase comes from hiding the SubD layer.)

How to model a car using polygons.

Although polygons have some disadvantages, they also have some compelling advantages. One of the main ones is that extra polys can be inserted into areas that require more detail. NURBS and splines, on the other hand, run throughout the mesh. When one inserts extra isoparms, these will appear from the beginning to the end of the mesh. In other words, if an isoparm is inserted at the eyelid, then this extra curve will flow all the way down to the base of the neck. If your software is capable of modeling with hierarchical b-splines (h-splines), then this will not be a problem. H-splines allow you to have one mesh with varying levels of detail in it.

How to create realistic and easily animateable tank treads.

This tutorial will go over some advanced modeling tools. It will show you ways to build more complex models without using primitive shapes.

How to model a shampoo bottle in maya.

There are different methods of attaching a SubD in Maya. These techques are not explained in Maya's documentation in-depth. So if you model in Maya's SubD's, you might want to bookmark this page.

In this tutorial you will learn how to create a really cool space ship using only a Primitive Cube and the Extrude Tool. We won't be adding too much detail to the ship because this is basically a beginners tutorial and we want to keep it simple. Also, I'm using Maya 6 to do this tutorial. I don't know if the ways I tell you to select certain things will be accurate for all versions of Maya, but the process will be the same.
