Contact Surface identificaiton

Hello everyone. I am quite new to the software and I am currently trying to find out how to identify contact surfaces for the knee joint (TF; medial and lateral, and PF). However, going through the literature, the authors mentioned that they used 3-Matic software for identifying these surfaces. However, the software requires a license. Is there an open-source alternative?

Hi Omar,

I am a little unsure about what you are looking for.
Do you have an DICOM file and are looking to segment this into STL?

Best regards
