DUH! Hello? Right in front of my face.

Thank you very much.

However, I keep getting the error message stating that it cannot convert my model to a terrain because it has no 'regular grid'. When I checked the manual it said to select all vertices and execute the merge command. I did this and it did not work.

Can you tell me why it will not convert? Is there a special number of vertices which is needed for models that will be converted?

What exactly is meant by 'no regular grid?'

It seems that no matter what I do I cannot get the converter to work.

I have tried merging vertices in my modeling software as well as in MED. I have tried quadrangulating the model as well as triangulating it. I have tried a few different models. I have opened .obj as well as converted with ventilators converter. Is there something I am doing wrong??
