![thickness_all3steps](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/f/a/fa42ad9e73a2e539bc2cc575a90ff27ad4293559.png) Hi, I have previously posted a question about how to measure the thickness ([Calculate thickness of thin muscle](https://discourse.slicer.org/t/calculate-thickness-of-thin-muscle/13444)) but did not come to any solution. I have followed this workflow: [How to analyze the thickness of the model - #2 by lassoan](https://discourse.slicer.org/t/how-to-analyze-the-thickness-of-the-model/2735/2) and I got the result as in the attached image. It seems like the inner and outer boundary are colored, but where is the medial surface? I need it so that I can measure the thickness (distance between inner and outer boundary) of this segment. After following the workflow, what does the colors indicate? Thanks in advance! ---
