While exporting as cgm, the page size increases due to Ellipse

In IsoDraw the Template size which I use is Width = 183.5 & Height = 227. I illustrate only inside the template.

But when I export the Illustration to CGM the width and height of the illustration increased.

If the Width and Height is less then it is not a problem for me.

But in most of the cases the size is higher then the template size.

I found this problem rises due to the partial ellipse which are created during illustration.

When the center point of the partial ellipse lies out side the template area the cgm size increases.

So I created a macro to select the ellipse whose center point is outside the template and convert it to Bezier.

But still the error occurs.

Then I found that even when the elliptical profile is outside the template(When selecting the partial ellipse and press F12) the size of the cgm increases.

I have attached an image through which you can understand my problem.

I want to select these ellipse whose profile and convert it into Bezier path.

Help me out in solving the problem.............

Thanks & Regards
