This is an Online version of my 7cad 3D Unfold desktop app.

No installation is required. All you have to do is isolate your 3D solid or a 3D mesh in a drawing. Clear all other unnecessary objects. Then, upload the drawing file to my web page and click Unfold button.

Wait for the Autodesk® Design Automation service to run for a while then you will have a download link to get your unfolded model drawing.

Remember the app doesn't work well for complex models. Some models exported from other software also have many zero or nearly zero faces. It is recommended the 3D model is decimated, and simplified first.
