I am a relatively new user to rhino and have been using an Artec 3D scanner to scan images and import into rhino with the intent to accurately measure volume. At the moment we have been practising on cylinders with known volume but I wanted to know the best way to accurately measure volume. I have been using the following sequence:
Import OBJ file
Select mesh and ReduceMesh (95%) again
Fill ALL holes
Calculate Volume (mm3)
However I have found I get different values depending on the percentage I reduce the mesh by, but if I don’t reduce the mesh Rhino can’t deal with the images. Can anyone shed some light on the optimal percentage to reduce by and why?
