Import cad model as a wire frame model option
1. It helps a lot when we import bigger tool data with cooling channels, if they are converted in wireframe. It will be easy to extract or generate curves for cooling channels
2. Right now, We use similar options available in CAD tools and use them as curves. But all the CAD tools doesn't have such option.
3. Even if option provided to convert surface edges to curves, also will be helpful.
4. Even if option provided to create a centre line for cylindrical features is also be helpful to generate cooling channels
