Hello, I am new to this forum and would like to know if Rhino is the right solution for me. I have experience in Fusion, Meshmixer and in the past with bocad, a 3D solution for steel construction.
In my spare time I work on grips for archery. To do this, I scan the grips using a scanner and then modify them before printing them out as 3D prints.
The modifications are primarily moving the holes, changing the hand rest (extruding inclined surfaces) and changing the width and inclination of the grip.
Exact values must be maintained for this. This is where classic tools such as blender zbrush etc. fail.
Attempts to generate quadmeshes and then edit them in Fusion are very difficult.
Hence my initial question. I am willing to deal with Rhino but would like to know if this is the right tool.
Enclosed is an STL as a sample.

One of my first jobs was an archery grip.
Reverse-engineering scans is not fun, but Rhino 8’s shrinkwrap may make it easier to get something quick, though proper tedious reverse engineering may end up being better depending on…well all sorts of things.
Rhino offers a 90 day fully functional trail version.
Having a look at the scan, i think you will need to remodel at least the precise / technical aspects.
Rhino on its own does not have a huge toolset for reverse engineering…
to find the position of the slot:
_PlaneThroughPt
_Circle _FitPoints
for me it looks like the task you describe is doable with Rhino.
A fast way is to do the technical surfaces with nurbs and the others with SubD.
…but pleas notice, rhino is not a implicit / feature-tree cad.
to build on what others have said, you may want to look at a plugin called Rhino reverse

or
mesh to surface
or
rhino resurf
or One that is current development- cyberstrak
Thank you very much for your helpfull comments. I’ll give Rhino a try.
