Hi you have two options. 

You either do a visualization or you add an element. The visualization would be removed when you exit the extension and cannot be interacted with. While the element would be a persistent design element in the model.

 

So visualization would be [`Forma.render.geojson`](https://app.autodeskforma.com/forma-embedded-view-sdk/docs/classes/render.RenderGeojsonApi.html) and the element would be [`Forma.integrateElements.createElementHierarchy`](https://app.autodeskforma.com/forma-embedded-view-sdk/docs/classes/integrate_elements.IntegrateApi.h...
The second is a bit complex to implement but you can see [this example](https://github.com/spacemakerai/forma-dynamo-extension/blob/8f5dbce7d180398308bf8759f0c6f593d713799d... from our Dynamo extension.

These will draw a 2d line draped on the terrain, if you are looking for 3d line in space then the answer is a bit more complex. Let me know if that was what you where looking for and I'll help you along 🙂
