converting a mesh to a nurbs surface for further editing is not the best / fast forward approach.
instead of uv mapping flowAlongSrf is the command you should target in any workflow…
to get a fast result - check how your slicer is handling intersecting meshes - most slicers will handle them, as if they where boolean-union"ed".
if so i recommend, that you use outward font as separate closed meshes, and use the initial mesh.
you will need a single nurbs-Surface (not a polysurface) to help you deform the font to 3d. - a target surface.
_loft might to this job. the most tricky part to get the curves.
…maybe a cone for the lower part is a good approximation. but you have to _rebuild it.
you may want to _offsetSrf inward to make sure everything is intersectining properly.
how to get the font:
draw it as solids
now you need a base / referance for this textobject
_plane (redraw the lowest surface)
_delete (the boundingbox)
to get the Textobject deformed.
(make sure, to target a single nurbs surface, if cirular ( a cone), you need to rebuild it first)
convert to mesh
export as stl
if you want to do it more proper you need to re-model (at least) the socket.
_mergeAllCoPlanarSrf will clean up the starpart
this will allow you more satisfaction, more lerning and enables inward text.
the socket is a loft between a square and a circle…
some of the workflow will be similar to above.
the main difference is a final Boolean Union / Boolean Difference
a satisfying closed polysurface, a proper single mesh to export…
