I design custom foot orthotic insoles in Rhino for my patients. The current method I use is to import a scanned STL file of my patient’s feet where I would manually draw cross sectional curves that overlay the mesh. I then use the loft function to loft these curves resulting in the desired insole surface that I would then mill out with my CAM system.
The task of manually drawing the curves becomes very time consuming when I have a large volume of orders. I am hoping someone may be able to suggest a much more efficient way of achieving the desired result. I come from no programming experience whatsoever but I would think there may be a way to write a script to create a “best fit” surface?
I also tried using the Section function that would quickly produce cross sectional curves however the curves are too exact to the mesh resulting in a very undesired and unprofessional shape. The act of drawing it manually allows me to make corrections and ensure a smooth comfortable and professional looking design.
Any help would be appreciated! I can provide a sample file if this helps to understand what I am requesting for.
