Clearing part of an objects wall

Need help? We are here.

I need to open up the wall that is on the side of an ellipse that was revolved around an object. Eventually it will be an air passage. I have tried copying the ellipse and rotating it 90º and then with great difficulty matching it to the face. I could not extrude to clear the wall. I tried drawing a circle on the face to see if I could extrude through the wall that way and it didn’t work. It seems like there has to be an elegant way to do this. I would think would be the function but I can’t get that to work either. I have attached two pictures that demonstrate what I am trying to do.

I found a way to do it but still not very elegant. I skecthed an ellipse and rotated it down to the side of the cylinder positioning it so I could extrude it to the point where I got a little more than 1/2 the ellipse opened. I then made a copy and notated it and positioned it so I could open up the rest of the side. I then drew an appropriate sized ellipse in the horizontal plane with the long end placed at the edges of the bottom opening and just extruded the horizontal portion of the body out. Not sure how I could do this to get the side to very specific dimensions. I could get the length or the height correct but not both. Picture of outcome attached.

Hi,
Can you show us the part or surface you want to remove ?
Thx

Thanks for the response. I added a picture to the original post. I need to clear out everything inside of the ellipse.

It’s hard to understand your model design given the two pics. Here’s my best guess of what your part looks like to me. Is this wall the part you’re trying to remove, as shown in my video?
If not, can you provide some clearer images?

That’s what I was thinking:)

For anyone else that ends up here with the problem I had the solution was a lot easier than I thought it was. I drew a radius from the center and added a plane tangent to the outside face. I drew a vertical ellipse on that plane and just extruded through the sidewall. Copied the ellipse to the top, made it a little wider to suit my needs and extruded down. This would have been easier if I did it before I did the chamfer. Chamfer went away while I was replacing faces to get rid of the gap above it.
