Hi, I think I heard Mesh is rewritten from scratch and now vertices are double precision. But seems like Rhino.Geometry.Mesh is still single precision (but I do see NGons…) Is there a new mesh class supports double precision or is it postponed to Rhino 7? I had a small house modeled by a mesh and …

In Rhino 6 there is the UseDoublePrecision toggle on the Mesh.Vertices object. See also [image] [RhinoCommon] double precision mesh vertices Rhino Developer seem that Rhino 6 has already implemented, great! https://developer.rhino3d.com/api/RhinoCommon/html/P_Rhino_Geomet…

[Memo]Probably I was only one who doesn’t know but I think leaving some notes is helpful… Mesh.Vertices always returns Point3f. But you can get a Point3d by Mesh.Vertices.Point3dAt() Mesh.Vertices.Add() now accepts both Point3f/Point3d Mesh.Vertices.SetVertex() now accepts both Point3f/Point3d …

But you can still call foreach(Point3d P in mesh.Vertices) which loops over Point3d. Unfortunately this is a misunderstanding, you would get a single precision vertex in double-precision format, because of implicit casting of Point3f to Point3d. Any enumeration of mesh.Vertices will give single p…

Agh… Yes, I actually wondered how it works… Sorry for the misleading post…

Hi. I’m struggling with this. Can someone please give a step-by-step to how this is enabled?

Does this help: [image] Mesh Vertices Precision Weirdness Rhino Developer As far as I understand it, traditionally a Mesh would only have single precision vertices. To keep this API going forward, but also be able to support double precision vertices, the support for this…
