Is there a way to use the new Quad Remesher which is available in Rhino 7 through API or scripting? I tried \_QuadRemesh, but it brings dialog.  
Can I provide the parameters in the script line and not have the dialog?

Would `Mesh.Faces.ConvertTrianglesToQuads(...)` do the job for you?

[https://developer.rhino3d.com/api/RhinoCommon/html/M\_Rhino\_Geometry\_Collections\_MeshFaceList\_ConvertTrianglesToQuads.htm](https://developer.rhino3d.com/api/RhinoCommon/html/M_Rhino_Geometry_Collections_MeshFaceList_ConvertTrianglesToQuads.htm)

# MeshFaceList.ConvertTrianglesToQuads Method

_Joins adjacent triangles into quads if the resulting quad is ‘nice’._

```auto
public bool ConvertTrianglesToQuads( 
   double angleToleranceRadians, 
   double minimumDiagonalLengthRatio 
)

```

Yes, in RhinoCommon: [https://developer.rhino3d.com/wip/api/RhinoCommon/html/Overload\_Rhino\_Geometry\_Mesh\_QuadRemesh.htm](https://developer.rhino3d.com/wip/api/RhinoCommon/html/Overload_Rhino_Geometry_Mesh_QuadRemesh.htm)

If you want to use the -\_QuadRemesh command with a macro then prefix the command with a hyphen “-” to suppress the dialog box.

This is may be what I want, but do you have also a C++ example? I am using the RhinoSDK with C++ only.

Looks like it is not (yet) in the C++ API: [https://developer.rhino3d.com/wip/api/cpp/](https://developer.rhino3d.com/wip/api/cpp/)

You may script the command from C++ like explained here:

Hey, I need to use this, but the results don’t seem correct. Could you see if I am doing something wrong? I am only interested in adjacency and coplanarity (the quad diagonals ratio doesn’t concern me).[inaccurateResults.gh](https://discourse.mcneel.com/uploads/short-url/nd3yV36gAIjPefxJOQPUORiYJ7X.gh) (14.1 KB)
