Hi Nick,

Unfortunately the mesher does not currently work in an order dependent way like this with some faces having priority over others.

If you change it to Output: N-gons, you can see that the vertices you don't like are getting added because of the top plane being divided (because Divide larger than "All" is set).



If you want to get all quads on the top face the best way is to use a retopology process in a polygon mesh modeling app.

I believe using vanilla Blender I may have resolved your issue.

I downloaded your 3dm model and imported into Moi3D 4.0
And exported to an OBJ with the following settings.

Imported into Blender 3.6.4 LTS





Next I selected the top ngon face and did an inset on it.

After doing the inset, I deleted the now smaller ngon face.

I then did a edge selection of the new hole.



Using Blender's gridFill I closed the hole with what looks to me, to be all quads.

The final result in Blender. It took me a couple of minutes in vanilla Blender to do this.

Blender is a free and very handy app to learn and use.

I hope this achieves what you want.

Cheers from Nova Scotia.

Also in Blender I used the commercial plugin, Quad Remesher which is usually my goto app for retopo work but it failed on your model and was not able to produce any acceptable output.

Next I imported your model into 3D Coat 2024.24 and converted to an voxel object and using the auto retopo I was able to convert, but the mesh is too dense with a count of 7,000.

Next I exported the object I retopp'd in 3DCoat into Blender and ran Quad Remesher of the 3DC object. I set the target for 500 quads and it gave me a remeshed object of 1200 quads.









It was must simpler and quicker to remodel the top in Blender.
