A Rhino Crash When Read External 3dmFile AllInstanceDefinitions;

Hi All,

I meet a crash when I read instance definitions in external 3dm file in grasshopper. The external 3dm file contains several blocks I need to import to this rhino file.

Rhino version is 6.10.18264.16071. I tried higher rhino version and the problem disappeared, but cannot run on this Rhino.

Do I have to upgrade my Rhino or something goes wrong with my code?

code below:

private void RunScript(string path, ref object A)

using(Rhino.FileIO.File3dm lib = Rhino.FileIO.File3dm.Read(path))
  foreach(InstanceDefinitionGeometry defGeo in lib.AllInstanceDefinitions)//this line trigger the crash



That is very old, and as you noticed newer version fixes the problem. You are about 20 service releases behind.

Why not?


No, code looks fine.
