Hello,

I am using **Fiducials** and the **MarkupToModel** module to generate an orthognathic splint from the position of the upper and lower dental landmarks in both the intermediate and final occlusions. I am getting pretty good results and would like to explore automating the process through Python scripting.

Currently, _I start by combining upper and lower dental landmarks_ in a single **Fiducial List** ;

 ![dental_landmarks](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/f/9/f9ce2a8aea07fbe321c5193f8180ce2ccebe1d57.jpeg)  
_Figure: Dental landmarks in green, only the lower teeth are shown_

Using the **Fiducial List** as an Input to the **MarkupToModel** module, I create a “tube” using the parameters shown on the screenshot below.

**Is there a way to interact with the MarkupToModel module programmatically using Python?** I briefly scanned the GitHub repo. and only found C++ code… Essentially, I just want to apply the parameters to every case.

I did not know how to interact with `loadable modules` until I found [this post](https://discourse.slicer.org/t/create-axes-model-using-createmodels-cli/674/2).  
To replicate the parameters above, I just need to use the logic;

```auto
logic = slicer.modules.markerstomodel.logic()
logic.UpdateOutputCurveModel(fidNode,modelNode,3,False,4,8,5,True,1,1,slicer.vtkCurveGenerator(),1,0.5,3)

```

Hi @Fluvio_Lobo ,

Can you please explain how you do this ? how do you make the thickness and how do you substract the occlusion ? do you use the model to substract the teeth from the tube or ?

if you can let me know your work flow it would be great.

thank you
