I need to develop a web-app which contains parametric CAD drawings. The user should be able to change the dimensions of the object that is then updated in the drawing. The app should then calculate the volume of the updated object for other calculations, basically to calculate the mass given a density value.

A promising option for the web-app would be Streamlit and I built my objects using FreeCAD. It should be possible to embed FreeCAD in a stand-alone python app, but apparently it is not possible to have it in a web-app.

Do you know any python module I could use to have this interaction between the user, the object and the remaining part of the algorithm?
