The "SM" in your search likely stands for the educational publisher Editorial SM, which provides technology textbooks for "Secundaria" (Secondary/Middle School). These textbooks often include licenses or tutorials for Solid Edge.

Instead of descargar (downloading), try ver en línea (view online).

Final Tip: If you absolutely need the PDF for offline study because you have no internet at home, ask your school's librarian. They are legally allowed to make one physical copy (photocopy) of up to 10% of the book for academic purposes.

Stop looking for the illegal download. Start using the legal loopholes. You will save time and avoid bricking your computer.
