I have tree branches of solid box meshes that have been cut with curvy surfaces. the output has at least two planar and parallel faces. The problem is that during the cutting of the solid box meshes, these planar and parallel faces turn from a single face into a bunch of faces. right now, I want to turn them into a single face to convert the solid cut mesh to Brep. Does anyone know how to do this?

Try the solid tools merge all faces command in rhino to see if that would work to start.
There is an unpopular plugin in smaller gh. If you want see the mesh, the larger one.
Please eliminate the plugin.
can you let me know the name of plugin?
I used mergeallcoplanarfaces
It did not work.
Core⊠something. The warning doesnât show up after the first time.
Not sure what youâre doing but this looks similar? And is way simpler.
P.S. I tried adding thickness to the extrusions but didnât quite pull it off.
This isnât quite the same thing but itâs really simple. The extrusions are âperfectâ closed breps because the faces are planarized before creating the boundary surfaces that are extruded.
Dear @Joseph_Oster thank you for your time. I want the subD version of the initial mesh that you have worked on it, to cut these extruded surfaces(polygon). It is important for the fabrication as I want to to have a continuous smoothness instead of being discrete. Therefore, as the mesh or polysurface (brep) couldnât cut the flat extruded polygons (brep), I have used the subD version of initial mesh as the cuuter and change the flat extruded polygons (brep) to simple mesh to use MeshSplit component. It is worth mentioning that when I wanted to use the FaceBoundaries as input for Patch component to have the polygonal mesh to cut the breps, the patch doesnât work properly. If it worked, I wouldnât have converted the breps to simple mesh.
Sorry, I still donât fully understand what you are doing but am intrigued about creating these extrusions.
I tried many different ways⊠This method uses a polysurface version of the mesh (yellow group) to split extrusions of arbitrary length (height?) that originate on derived planes, one per face. After that, the bottom cuts are extruded to a âHeightâ slider value (blue group), edges are lofted between inner and outer extrusions and joined to create closed breps.
Smaller faces can fail to create good extrusions if âOffsetâ and âThicknessâ values are too large.
Thank you @Joseph_Oster
I apologize for late response.
Your code has worked; however, as you can see in the image there is a problem that affect the entire form. I have baked both the polygonal meshes and the Breps. Breps has passed thorough the meshes (yello parts).
I baked the yellow group to a blue layer and the green group to a yellow layer. Looks good to me?
P.S. I see issues like you do when I bake the original mesh to the blue layer instead of the TriRemesh âTâ output (yellow group). Is that what you did?
*Your topic probably needed to be âSolid mesh to nurbsâ as you seem to be requesting a single unified solid (closed brep) per each multi-solid mesh group.
Check if this workaround* helps:

*It does perform some edge/face cleanup while preserving overall shape.
See details below.
Yes, I have used polygons, output of the Triremesh, as it gives me a more smooth face.
I appreciate you for your responses dear @Joseph_Oster
Dear @René_Corella thank you for your time and response. I check your method today. Thanks
