Getting Error in Unity

[AcKeskin]

I get the following error even though I have added "G3_USING_UNITY" to the Scripting Define Symbols
NotSupportedException: ToVector3d: unknown type UnityEngine.Vector3 g3.BufferUtil.ToVector3d[T] (System.Collections.Generic.IEnumerable1[T] values) (at Assets/Scripts/geometry3sharp/core/BufferUtil.cs:210)
g3.DMesh3Builder.Build[VType,TType,NType] (System.Collections.Generic.IEnumerable1[T] Vertices, System.Collections.Generic.IEnumerable1[T] Triangles, System.Collections.Generic.IEnumerable1[T] Normals, System.Collections.Generic.IEnumerable1[T] TriGroups) (at Assets/Scripts/geometry3sharp/mesh/DMesh3Builder.cs:170)

Have you add the namespace in the script

using g3;

How are you installing it?

You have to install it as source and not as the .dll from Nuget - to allow the compile symbols to work.

There is a UPM package available that correctly installs in Unity (but you still the Compile Symbol) :
