Basic rotate model example

I am having extreme difficulty finding a basic example of rotating an imported model. Can someone please help?


This was the third time I asked this question before it actually posted without auto deleting so I was a little brief. I have tried plenty of examples online but none of them actually work so I am asking here. Thanks guys!

I think there are some examples in Sandcastle
For instnace


I tried this example and it rotates the object in a pattern that doesnt make sense. The model is rotated on multiple axis instead of one with the example code. I have tried multiple models just to make sure it wasnt that the model is incorrect.

Here’s a Sandcastle example that load several different models and rotates them based on a heading. pitch, and roll.
