Locking views in .dwg

[arnie_6]

Hi
Occasionally I have a problem when the drawing view in the dwg file moves to reflect the position of the model, recently did a repair install and can't remember what I did before this to prevent it happening, can anyone help please?

Not sure I understand the question?:?

Thanks fo rthe reply, when i click on the part in the .dwg and it opens the model, Sometimes when choose to reset the view to look at a certain face of the model, the model view chages to a strange angle, when i close the model and go back into the dwg this has also moved, and all my dimensions are out of place? it only happens when i choose 'look at'
