When I attempt to use the EXTRUDE or PRESSPULL commands, they both either don't recognize the lines or throw an error saying "Cannot sweep or extrude an object of this type." The DXF was exported from Inkscape where I drew it as an SVG. I've tried exploding the block into splines as well, but this does not work either. The SVG and .dwg I'm working with are attached.
