Hello!
I have an STL file which contains the facets and vertices. My concern is about the way the facets are saved because I have noticed that the facets don't seem to have any common nodes with each other which is not obvious for me, so it would be very much appreciated if anyone can tell if this is normal or I am having some problem in my file!
Note: I have attached a screenshot of the STL file
Thank you and best regards!facets_stl.png

Attach your file.....the faces/ triangles should be sharing nodes.

Thank you for you reply.
yes I agree that they should by they are not sharing nodes and the model seems to be correct!
Any ideas?!
Note: Please find attached the STL file and the facets and the nodes .
Thank you and best regards!

How are you reading the file into MATLAB? If I follow the example on the stlread documentation, I can import and plot the mesh.
data = stlread('femur.stl');
trimesh(data,'FaceColor','none','EdgeColor','k')
The interesting thing is the numbers from the various files are different.
  • stlread imports 33332x3 points and 66670x3 ConnectivityList
  • Your screenshot shows the values similar to what I see in ConnectivityList, but 178726x3 of them.
  • fv contains 66674x3 faces and 200022x3 vertices. How were faces and vertices created?

can anybody tell me how should I overlap this two stl models, there is gap between this two files. I want to overlap them on each other to measure how much the deformed model has deformed compared with non deformed model.

You should ask this question in a new post.
