file format questions

[Hathaway K]

Dear Dr Fang:

Sorry to bother again, I drew a 3D model in SolidWorks, and I want to turn it into mesh file using ios2mesh, what format do I need to convert my model into? 

Best Wishes,

Hathaway

please check out the bottom section of the iso2mesh workflow diagram

https://iso2mesh.sourceforge.net/cgi-bin/index.cgi?Doc/Workflow

it can only read a limited set of mesh formats. Solidwork files are not supported.

you will have to check if any of the formats is listed under the Export feature of solidworks, or use other converters such as MeshLab (https://www.meshlab.net/) to convert it to a format that iso2mesh can read.

Thank you very mush, Professor Fang, I'v met a new problem, I turned my model into .STL and imported it to MATLAB, then I used surf2mesh and an erro accurred. 

I put my code and the error in the fic below, Could you please help me to see what's wrong?

Thank you for your time,best wishes,

by the way, this is my model:

this is a common error, in most cases caused by self-intersecting triangles present in your model.

if your model is a single closed surface, you can call

[no, fc]=meshcheckrepair(v, f, 'meshfix');

to detect and repair these triangles. you can then pass the surface to s2m.

Thank you for your time, I used "meshcheckrepair" but the output is empty, does that mean there is nothing to repair? And I still got the "Tetgen command failed" erro, is there something else I can do?

[Qianqian Fang]

no, that means meshcheckrepair/meshfix finds almost everything in the input is incorrect and decided to delete all.

please at least plot your imported mesh and examine it visually. also, please read the documentation from our wiki, and you should be able to use iso2mesh efficiently on your own. while I am happy to help, I can't do every step for you.
