Maybe you’ve already seen this thread, but I am trying to generate single-element slab-edges from a group of model curves. My issue is, I have no idea how to construct a ReferenceArray.

> Hi Thomas, Unfortunately, that will essentially get me the same result. I am actually hosting the slab-edges to model curves. I will ask in the main forum. Thanks for all of your help so far! Cheers, Matt

Has anyone done this? My python skills are very limited…

Hi @m.owens,

It is very simple :

```auto
references = IN[0]

#Constructor of referenceArray
yourReferenceArray = ReferenceArray()

for reference in references :
	yourReferenceArray.Append(reference)

```

In the same way you would instantiate any other class using Python:

`referenceArray = ReferenceArray()`
