3.1.0 Rhino Model - Double precision in Speckle viewer

weird handrail.3dm (235.1 KB)

Hello folks, in Rhino 8.15.25013.13001, using speckle.rhino.installer-3.1.0, the preview of this handrail off in world space is getting butchered:

Something to do with double precision meshing out of Rhino? Hopefully this .3dm is enough to recreate it.

Hi @chris.welch,

We have investigated on our end and it looks like a mesh conversion issue on these exceptional handrails.

Logged it to fix if possible. Thanks for reporting

As an interim we ended up meshing them in GH by:

  • Getting the bounding box
  • Moving the handrail center-to-center to 0,0,0
  • Meshing at 0,0,0
  • Inverse transforming back to world space

Which is something you could do programmatically when generating the preview geo for speckle
