I'm a owner of a small machine, and fabrication shop, and I've got some DXF files that was sent to me, and I cannot open them without some  kind of cad program, looking for a solution.

Autodesk 360 viewer:https://360.autodesk.com/viewerDraftsight (free): https://www.3ds.com/products-services/draftsight-cad-software/Or upload dxf file here and someone can print it to pdf.
