I am trying to model an ellipse with two circular cuts inside :

Ellipse with 2 circular cuts

After some planning, I came up with the following topology :

Ellipse topology

While technically all quads, the large ones in the middle are almost triangles and really stand out in terms of scale. Since this is a flat surface, the subdivision modifier still looks nice, but I really wonder if there is a better way of doing this.

EDIT : here's the full model for clarity :

  • $\begingroup$ If this is a flat surface you could use a ngon, also, if you use a Subdivision Surface modifier you could use less vertices for your holes, like 8 $\endgroup$

  • $\begingroup$ Thanks for your feedback. It's definitely a flat surface, but I plan to extrude it to give it some thickness. I tried doing that with an N-gon & 8 vertices for the holes, but the subdivision modifier makes a huge mess of the N-gon unfortunately $\endgroup$

  • $\begingroup$ maybe show an image of the final object you're trying to achieve? $\endgroup$

  • $\begingroup$ I edited the question and added a picture. It really looks nice, but I'm beginning with Blender and am really trying to do things the right way. $\endgroup$

If you use a Subdivision Surface modifier, you don't need so many vertices, you can use 8 vertex holes, and also an ngon like that should work:

  • $\begingroup$ Hmm this doesn't seem to work for me, I get a lot of pinching after subdividing. Thank you for your help though, I guess I'll just watch your videos to get better at modelling! $\endgroup$

  • $\begingroup$ you may need to inset the ngon, could you please share your file? $\endgroup$
