STL file from catia apparently empty?

I tried opening the file using stlread. It adds some descriptions of the file to the command window and a new variable to workspace, implying the file has been successfully opened (see image). However, when I click on this new variable, it appears to contain no data. The file itself is 37 bytes. How can I fully read this STL file from catia in matlab?

close all; clear all; clc
 fv = stlread('Part2.stl');

I'm using R2014a

If the file has 37 bytes only, it is very short. Maybe it does not contain any data? Please post the STL file also.

I did try attaching the file, but it gave an error saying I could only attach certain formats.

You may zip it and attach the zip file.

[Mike AA]

Ok I attached the zipped file to the original question.

It looks like the file have no data.

I am getting error:

Error using stlread (line 52)
Input file must contain at least 3 unique vertices.

As I thought, the file does not contain any data. The contents is really:

solid CATIA STL
endsolid CATIA STL

Of course, this does not allow to import any data.

"How can I fully read this STL file from catia in matlab?" - you are reading it completely already. The actual problem you have to solve is: How can you export the data from the other program. But this is not a Matlab question.

I wonder why it creates a new variable though if there's no data.

The data will have nodal connectivity (fv) of size m*3 and coordinates p*2. It tried to initiate the nodal connectivity ad the data is empty, you got a empty matrix.
