CoatCAL started from a real task at work. I was asked to download STEP files, measure their surface area, convert the result to m², and use that for coating calculations in our coating shop. Doing that repeatedly in CAD felt unnecessarily slow, so I started building a browser tool that could do it in a few seconds. CoatCAL currently supports STL and single-body STEP/STP files up to 500 MB, with surface area, X/Y/Z dimensions and a 3D preview — all processed locally in the browser. I’ve validated the STEP calculations against Creo, but now I want real-world testing. Please try to break it 😄 If you have a weird, large or messy CAD file, throw it at CoatCAL and tell me what happens
