Passing objects in classes between components

[studioselva (Info)]

I finally found the solution in this thread:

"object reference not set to an instance of an object"

@guilleramirezc the issue here is that, when passing an object from one component to another, the next component doesn’t know exactly what it’s dealing with. The only way it can figure things out is by duck typing or using some kind of introspection. In your particular case, when the slider changes, and thus the property of the class changes, it receives a guid which needs to be coerced to a curve object. That same logic should be applied to other types. Attached the solution nullobjecterror.gh …

So, I’m just posting a working setup for future reference for anybody wanting to pass geometries between custom classes by what was proposed by @AndersDeleuran and use rhinocommon directly instead and also solve the problem of null object errors:
