Summary: Demonstrates how to obtain the insertion point of a block.

How to get the basepoint coordinates (x,y,z) of a block instance?

See the following sample code:

For example:

ON_3dPoint BlockInstanceInsertionPoint(const CRhinoInstanceObject* instance_obj)
{
  ON_3dPoint pt = ON_UNSET_POINT;
  if (instance_obj != 0)
  {
    pt = ON_origin;
    pt.Transform(instance_obj->InstanceXform());
  }
  return pt;
}

public On3dPoint BlockInstanceInsertionPoint(IRhinoInstanceObject instance_obj)
{
  On3dPoint pt = new On3dPoint(OnUtil.On_UNSET_POINT);
  if (instance_obj != null)
  {
    pt.Set(OnUtil.On_origin);
    pt.Transform(instance_obj.InstanceXform());
  }
  return pt;
}
