In Rhino 8, converting SubD to Brep or to mesh via Quad Remesh modifies the geometry.
How to do boolean operations on SubD without using Mesh or Brep?
Many thanks
in short - the concept for boolean-operations does not exist for subD
in addition:
in grasshoper check subD-Fuse component
and for modelling - some combiations can be done with spliting and stitching.
(_unweldEdge _explode _stitch… but only if the number of edges match)
show an example an i am sure, there s a solution for it.
Many thanks for your reply,
Please see attached an example,
SubD to BRep or Mesh lose geometry,
Work around is bare mesh and Catmull Clark,
But I would like to maintain BRep as far as possible.
I will try Fuse, split and stich later this week.

Thanks again
Dear @Guillaume_Laurent
your SubD has 12 Faces - and 2 starpoints, with 6 connected faces each.
the algorithm to convert ToNurbs has some limitations at starpoints.
you can not set the parameters for ToNurbs in Gh1 - but you can do it via scripting
see this topic:
in your case - because of the special, reduced typology a workaround is to subdivide the subd twice before converting toNurbs.
this has to be done with a script or with a plugin.
rhinocommon subdivide
hope this helps - kind regards - tom
