In case to make maximum of quads inside an OBJ file
this free one can be also a cool solution! ;)

So for input this image inside Moi with SubD



Free Sparc3D calculate an OBJ
file from the image!


Then free Instant Mesh (some automatic repairs can be made with the free MeshMixer not made here )
If you want more detail just explore the video above about Instant mesh https://moi3d.com/forum/index.php?webtag=MOI&msg=11863.18


Then Moi SubD create from File


or by SUbDiv beta 9 (byMax Smirnov) some funny results can be made in taking different % ! Don't take Preserve corners !




With automatic repairs from Mesh Mixer (scale is maybe 1/10)
then Moid SUbD from create file... we can see there no more holes or other disagreaments (alone faces etc) but drawing of patches are also changed! :)


Not sure that SubDive beta9 can play! :)



Works with Subdiv9 ! ;)


Load the Subdiv then Subdiv beta 9 but cant't make some faces but keep the impossible faces selected so delete et voila! :)

Ok so If I understand this right....
The options I have is
1. remesh the object and then try to subD it or the remesher can create a smoother surface? Maybe Rhino shrinkwrap can accomplish something similar?https://www.youtube.com/watch?v=ETeytCD7HTA at 4:06 or is this basically the same as the quaremesher?
2. Try to redraw the result in a polygon based software so I can subd it
3. Attached I try to recreate the shape with Moi3d subd tools.

If I 3d print it which is going to be my first choice it does not have to be abnormally smooth.
however I would like to machine a version of it which the result needed would be the smooth surface of the attached pic.

In the end what ever I use it needs to come back in Moi for the mounting points.

Tnx!
