These lines are grouped with the line hatching for the exterior walls in the viewport. Can’t find any reference in SketchUp, They seem to be LayOut lines. I have to pull apart the viewport to delete them other wise the viewport will not print the hatching properly, which breaks the link. These extraneous lines do not effect the drawing on the computer screen, only when exporting to pdf or printing. This phenomenon is only happening with this one viewport.
