Hello, I am trying to analyze surface scans of bird beaks as part of my PhD research project. I need to count lamellae (teeth like structures) as a ratio of the bill length. I have been able to place my landmarks and measurements to the top surface of the bill but the issue i'm running into is that I need them to be visible from the bottom side of the bill also to do the rest of my measurements and landmark placements. Is there a way to place a landmark through the 3d mesh or have the arrow attached to landmark be double sided. Alternatively is there a way to draw/place a line through a landmark or the mesh itself so that I can be able to follow it for my other landmark placement?
We recommend trying the following things:
1. From the View menu, you can change the surface opacity from 100% to 75%, 50%, or 25%. This will allow you to see the landmark points through the surface.
2. You can also align the slice-window cross-hairs to your specimen such that one of the slice planes align to the direction you want to follow from your landmark point.
The video below walks through these steps. Take a look at the video below and let us know if this helps you
