What I do to get measurements out of CAD software automatically is to
export as one of the text CAD formats and read the data in directly.
.OBJ files are my favourite (also called Wavefront files) because the
vertices are just a line starting with v followed by the x, y and z
coordinates. Sometimes there are additional data points due to normals
and the like but these are usually optional in the export.
The difficulty with a complex shape is identifying the vertices and I do
this by labelling them in the CAD software (either as a named group or
object). This name is usually found in the preceding line as g followed
by the name for a group or o followed by the name for the object. The
only other thing of interest in OBJ files is lists of vertices which is
a v followed by 3+ integers. These are harder to decode because the
integers are indexes of the vertices.
It sounds like exporting as OBJ and reading all the lines starting with
v is the way to go for your problem. I'd use Matlab but you can just
read the whole things into Excel and edit by hand. Then export in your
favourite morphometrics format.
Cheers
Bill

Hello,
I work with tridimensional images, which I orient using a number of
planes I draw with Rhinoceros. I am interested in drawing a number of
points with Rhinoceros and export the 3D mesh with these points so I can
replace these points for landmarks using Landmark software.
Is it any possibility to import a mesh with added points into Landmark
software? I should use Rhinoceros to draw the points because they must
be in reference to the planes abovementioned.
Thank you very much.
