Hello I´m a mechanichal engineering student and I´m a total beginner in Matlab. I have a .txt file with 3 columns (x,y,z data) taken from Leica and Confocal Uniovi Image software. And i need to import that .txt file and 3d plot it but as said I´m totally noob and dont have any ideo how to start.

Also, I need to import more than one .txt and compare them (to measure the tool wear in a CMC grinding wheel

Any help is welcome.

Thanks

Great starting place is MATLAB Onramp. It covers the besics of using MATLAB, including importing data and getting help. It doesn't cover 3D plotting, but you can't do that until you get the data into MATLAB.

Once the data is in MATLAB, consider exploring the interative Create Plot live task. Do you know what type of 3D plot you want to create? You might be interested in scatter3. If you want to creaet a mesh or surface, you likely need to do some reshaping of your data.
