Changing Radius Window Family to parametric Partial Radius

[vanderloo5]

I'm not the greatest at Family creation so I could use some help here. I actually have this Marvin arched window in my Master Bath and am drawing plans for a remodel. But my window is not a full arch. It's an ellipse that is 50 1/2" wide and 17 1/2" tall at the peak. I think that is a 27" radius. How can I make this window family parametric so that it doesn't need to be a full arch?

Hopefully the shape can be generated by entering the width and radius? Or width and height at the peak?

I guess technically it's not an ellipse because there is only one (clipped) radius.

Thank You

You just need to delete the formula for height in the parameters window.

Then you need to create the sweep path using a partial ellipse. Then you can align and lock the peak of the ellipse.

You will need to make these changes to nested parts in the family and the opening cut as well.

You may also need some additional ref planes to be able to lock things to.
