Apple Magic Mouse Singularity issue

Hello All ! Hope you are doing well.

Actually I am trying to model apple magic mouse. However while surfacing the top face of it and analyzing it via zebra, I am not able to get a good flow of the surfaces. There is a big bulge throughout the surface and a singularity issue on the nose. I have attached the screenshots. Please Help !!

The surface is way too dense.

For high quality surfaces use as few control points as possible.

A good start is to draw a rectangular surface and change the degree to 2 in both directions. Start deforming the surface and in side view with history enabled, project a line to the surface.

In top view draw the desired contour and compare that with the projected line. Keep deforming the surface and watch the projected line update while you do so.

If you need more control raise the surface degree with ChangeDegree. Once the surface matches the desired contour line close enough you can split the surface with the line.

Additionally have a look at @sgreenawalt s YouTube series on primary surfacing (channel thirtysixverts)
