frame animation: how to 'lock' part so it doesnt move?

[skiddy]

i have created a part (using relations that alters after regeneration)



im trying to make a basic frame animation.... taking snap shots from pro e after each regeneration.



my problem is that the model changes slightly its position on the screen.



Any way of 'locking' my part?

Is it moving slightly becuase the size of the part is changing slightly? Pro/E tends to alter it's zoom based on the size of the part. If this is the case, then try making a datum feature of a fixed length slightly larger than the part and layer it off of the screen. That way Pro/E will think the overall part size is a fixed size.



You can use a datum plane, then redefine it's attributes to fit to a particular size, or use a datum curve.
