All this fuss about properly centering models first when you start the process of creating new creatures following Remdul's tutorial made me decide to list the steps I've had to follow:

1. Open your model's file in 3D Studio Max/Gmax.
2. Select the mesh.
3. Select the 'Move' button.
4. Set the X, Y and Z coordinates to 0.
5. On the right panel, click on the 'Hierarchy' button.
6. Click on 'Affect Object Only'.
7. Click on 'Center to Pivot'.
8. Click on 'Affect Object Only' again to de-select it.
9. Click on 'Reset Pivot'.
10. Apply an XForm modifier (Modifiers->Parametric Deformers->XForm)
11. On the right panel, expand the XForm modifier
12. Select 'Center' .
13. Set the X, Y and Z coordinates to 0.
14. Select 'XForm' (the root of the modifier).
15. Set the X, Y and Z coordinates to 0.
16. Select 'Gizmo'.
17. Set the X, Y and Z coordinates to 0.

That should be it. You can re-save your file now, or save it under a different name if you prefer. You can also export them to .tpm now.

Notice that this is for single objects only...
Also, there's no guarantee that the bones will be properly aligned at the end of the process described by Remdul, even following these steps.

Actually, these may not be all the steps needed - they only make sure that the object's pivot is properly centered, but the orientation and scaling are another story. More about that later.

Thanks -- if I ever take up modelling, this will most likely save me from ripping my hair out. :)

Now, to rotate the model so that it's properly oriented, there are some additional steps. They could be combined with the previous ones, but I think it may be a better idea to collapse the modifier stack and start from anew. So, after you've finished centering the pivot of the model and the model itself at 0,0,0, the follwoing steps would be needed.

18. Select the mesh again if needed.
19. Collapse all modifiers.
20. Select the 'Rotate' button.
21. Set the X, Y and Z rotations to 0.
22. Apply an XForm modifier.
23. On the right panel, expand the XForm modifier
24. Select 'Gizmo'.
25. Apply the necessary rotations to the X, Y and Z axes until the model is facing the desired way.

Now your model is ready for saving and/or exporting (again). As you can see, for adjusting the rotation there are fewer steps involved than for properly centering the model.

Later I'll add the steps necessary for properly scaling the model...

Well, by now the model may have become distorted after aligning the rotations if the different axes had been differently scaled... after rotation, the scaling doesn't match the proper axes anymore. Or you may simply decide that the model is too big and want to scale it down. Again, the steps could be taken together with the previous ones, but it may be better to collapse all modifiers again. So, these are the steps to follow:

26. Select the mesh again if needed.
27. Collapse all modifiers.
28. Select the 'Squash' button (the lowest of all three 'Scale' buttons: 'Uniform scale', 'Non-uniform scale' and 'Squash'). You need to click on the lower right-edge of the 'Scale' button to be able to select one of the three.
29. Right-click on the 'Squash' button and the 'Scale Transform Type-In' window will pop-up; take notes of the values along the X, Y and Z axes and close the type-in (or you could have read them directly at the bottom of the screen, too).
30. Set the X, Y and Z scales to 100.
31. Apply an XForm modifier.
32. On the right panel, expand the XForm modifier
33. Select 'Gizmo'.
34. Right-click on the 'Squash' button to open the type-in again.
35. Apply the proper scales to the X, Y and Z axes; you can do that by taking the ones you noted earlier and taking into account which axes have been swapped by the rotation.
36. If you think that the model is too big or too small, you can apply a new scale to all axes (the same, this time), and close the type-in.

Now your model is ready for saving and/or exporting. This time no more changes should be needed. Any scale 'fine-tuning' can be done later in TresEd, or while you're following the steps of Remdul's tutorial.

OK, now that you have learned how to position, align and scale a model, I'll explain how to use that to prepare a dinosaur model for rigging it in TPDC. Since it's a lengthy process, I'm placing it in a separate thread here.

Why don't you just make this into a Wiki article machf?

I'm not really a fan of the whole wiki thing...
